During the last couple of days there have been a few small, but still noteworthy earthquakes along the Bárdarbunga fissure swarm. I thought we should bring them to light and put them slightly into context, but first a brief background.
Background
The Bárdarbunga fissure swarm is the longest of Iceland’s fissure swarms spanning 180 kilometers to the south from Bárdarbunga, and about the same distance to the north. It has since de-glaciation been the most prolific in having rifting fissure eruptions with at least 5 known eruptions along the southern part of the fissure swarm (Veidivötn/Vatnaöldur) and at least 3 in the northern part of the fissure swarm.
It contains at least two active central volcanoes, Bárdarbunga itself (a massive caldera volcano) and Hámarinn. To the north you will also find the seismically active Kistufell table top volcano, and Iceland’s largest shield volcano, Trölladyngja.
The fissure swarm is responsible for the largest known historical flood basalt eruption, the more than 30 cubic kilometers Thjorsáhraun. The fissure swarm stands for about half of the Icelandic lavas during post-glacial times.
During the last 10 years persistant uplift have been measured at both the Hámarinn and the Jökulsheimar SSW of Hámarinn, lately there have also been more un-localized uplift around the fissure swarm.
The two earthquakes just north of Vatnajökull are at Trölladyngja and the four southernmost are running from the northern point of Vatnaöldur up along the Bárdarbunga fissure swarm.
Trölladyngja
On Sunday two deep earthquakes took place under Trölladyngja at a depth normally associated with magmatic movement. They could be associated with either movement of magma up into a deep chamber, or production of fresh magma. One should though note that they were small in magnitude.
Sunday 16.06.2013 20:23:11 64.893 -17.188 18.5 km 0.7 99.0 2.9km E of Trölladyngja
Sunday 16.06.2013 20:22:58 64.879 -17.176 18.6 km 0.8 99.0 3.9km ESE of Trölladyngja
The likelihood of this entailing a future eruption at Trölladyngja is very small; it is more a symptom of erratic behavior along the Bárdarbunga fissure swarm as it is slowly inflating at depth.
North of Veidivötn
A series containing 4 small earthquakes took place at shallow depth at the northern end of the Vatnaöldur fissure and northwards under Vatnajökull. These earthquakes were not magmatic in any way; instead they were caused by isostatic rebound relieving pressure. It is though a sign of mounting strain in the area.
Monday 10:51:40 64.282 -17.665 5.9 km 0.4 99.0 23.3 km SW of Grimsfjall
Monday 09:32:05 64.309 -17.782 0.1 km 1.4 99.0 19.8 km S of Hamarinn
Monday 05:36:44 64.320 -17.721 0.1 km 2.1 99.0 19.1 km SSE of Hamarinn
Monday 04:36:58 64.219 -18.121 0.1 km 1.7 99.0 17.5 km NNE of Laki
As time goes by and the strain increases we will see more of these earthquakes affecting the Bárdarbunga fissure swarm. In the beginning the picture will though be confusing, but as time goes by I fully expect the picture to get clearer, but remember, we are looking at quite some time before something will happen. Perhaps it will be as short as a few months, but more likely years, or even decades, and in the end a whole lot of nothing may happen.
Update
Image by the Icelandic Met Office. Lineament showing as red dots in line.
I seem to have grown slightly prophetic as I am nearing old age. A couple of hours after posting this a small lineament earthquake swarm took place almost due east of Bárdarbunga volcano. All of the earthquakes were small, but one of them was at a depth indicating magmatic movement, 21.1km. This is either at the extreme outer edge of the Bárdarbunga fissure swarm, or inbetween this swarm and the Grimsvötn fissure swarm. This shows how large the area affected by the magmatic pulse is. Right now we have to wait for about 3 to 5 days to see how the GPS patterns for the area will be affected.
Short update on the update. Thanks to our hardworking friends at the IMO night shift we now know that there were 3 earthquakes deeper than 20 km (21.0, 24.3 and 21.1). If you check the link the lineament of those earthquakes is looking even more interesting.

CARL
VolcanoCafé 
As I said in private post earlier today. ”Yes, right.”
Lots will not happen for long time. Then it will and note, not same place as last time.
My saying it possibly be next be in Vatnoldur or Eldgj’a,
but there have not been any qakes there so less likely.
Then I mean, we have to face such on 236 years average or so. Last time around we were only 30.000 souls and had no ships or aeroplanes for get food in or out.
Now we have, but weak enonmy after several well placed persons performed a triple bank robbery in broad dayligt, and some still trade. But I have no worries, World Economy will fall with us this time.
And that was the world famous Icelandic stoicity for you 🙂
As far as I can see there is no activity on the Éldgja fissure swarm on the GPSes, so Vatnaöldur is and option. My personal guess wouldbe somewhere in between V and V.
Yes, I guess between V and V – but not expert on how long a fissure, possibly 15+ km*
Veidivotn and Vatnaoldur?
I still think an eruption like that, can occur anywhere within the next 100-150 years.
I am not as good as Geolurking graphs, but something tells me that the distrubition of probability of such an eruption peaks around 2050 or something like that +- 10 or 15 years. Not really now.
And that is why I wrote decades up above in the post.
But, we are definitly seeing signs now. My guess, we will see them for quite some time.
Iceland gives me the desire to live forever. Darn It! I am never around when something exciting happens !!!!
Thank You, Carl
You are welcome, and welcome!
Thank you Carl! Plenty of earthquakes to ruminate about next week when my vacation starts 🙂
And here the truth about Fourier transform:
http://www.smbc-comics.com/?id=2874
Ouch… the pain… That must have been the worst math joke ever…
And the worst is, you will not be able to forget it, ever. 😉
Oh the horror… 12 years of perfecting my math skills… and it is just gone 😦
Question is, what do you do if it’s a fast one ? wave or let it ?
Thank you Carl!
I am now working with the film: “A bumby ride over Iceland’s glaciers & volcanos”,starring; Ejyafjallajökull, Katla/Myrdalsjökull, Grimsvötn, Hvannadalshnjúkur/Vatnajökull. It’ll take some more days and hours to get ready for the cinema show…
We are all lookin forward to it 🙂
Tell us when it is ready so we can make a post about it !
I will! 🙂
And the oddities seem to really be coming about.
Now we had a 21km deep earthquake out in nowhere land under Vatnajökull.
It is kind of inbetweenish between Grimsvötn and Bárdarbunga fissure swarms.
I seem to have been prophetic when I said that we would be seeing more odd earthquakes. I just did not expect them within the hour.
http://en.vedur.is/earthquakes-and-volcanism/earthquakes/vatnajokull/#view=table
Thinking of changing … ”Yes, right” to ”yea, right dude”
|only kidding of course| but watching
if anything develops the IMO will decide on an overflight,
or throw in some stone tablets first
Interesting earthquakes.
It seems that it was after Grimsvotn eruption that these odd quakes start to occur more frequently around the dead zone. Or perhaps I am seeing something that is not there.
Occasionally we have seen a few in Veidivotn, and a few around the edge of the glacier towards Laki. They are still rather infrequent to be cause of concern.
Magma seems to be pushing under the top mantle above the entire Vatnajokull and this is causing a few quakes along the Bardarbunga fissure region. I dont know where it will be the weakest link of all these weak spots: SW of Grimsvotn, Hamarinn, Kistufell, Trolladyngja… and as Carl said in previous post, volcanoes can take many intrusions before erupting.
I still remember the weird events (to my mind) of July 2011. When in space of a few days (less than a week), Hekla almost erupted, and Katla and Hamarinn either had small subglacial eruptions or large geothermal events. It was as if in that week magma was pushing beneath the entire extent of south/southeast Iceland. I remember that even Surtsey had a significant earthquake that week.
Could it be that the hotspot pulsates all across and magma creates tension at the lower crust everywhere across a large part of Iceland? Just my rumblings….
Yes, at least almost. But it would be a long explanation. I think I will have to shift around the Laki chapters again and go for nr 5 before 3 and 4…
I would bang those out before Something Happens and we get all distracted…
I thought I had time for those… I still think I have that. But, I will though change the order once again so that people have a bit of background on what is happening and how to interpret it. But, the part 5 will not be in before wednesday. Real life interference… 🙂
Small, but beautifully formed:
http://en.vedur.is/earthquakes-and-volcanism/earthquakes/vatnajokull/#view=map
Yes, and absolutely out in nowhere land, after looking at the satellite image map of the fissure swarms under Vatnajökull I noticed it is smack bang in between the swarms.
And the 21.6 km quake just gotta be magmatic.
Edit: Yes, it is.
Guess this is just a single long earthquake.
And likely quite deep and magmatic. If the spot is correct, it is near Gjálp fissure.
Indeed quite prophetic. For both of us, talking about this. The hotspot pulsates and creates this odd quakes in the last few hours.
I would guess that, with all pressure at the low crust beneath central Iceland, tomorrow Hekla will erupt!
It is actually almost directly due east of Bárdarbunga, so it is almost 90 degrees away from Gjálp.
To be honest, I knew it would be coming for a couple of weeks now. But I have asked quite a few people to not talk about it openly on VC before the quakes started. I did not want to give anything away for the Daily Fail. It was the reason for me to start writing about the Laki eruption. I though thought I would have time to finnish that one before the activity started to show as earthquakes and magmatic movements.
We will probably see an increase in eruptions from the central volcanoes before, under and after if the main event occurs. Hekla might be one of them. But I would be surprised if we did not see Torfajökull and Bárdarbunga first, maybe also Hámarinn.
Carl, let me guess: what you know in secret is the same thing that I do know also, but its not a big secret!
It is a fact that many have speculated that the hotspot activity comes in cycles, every some 140 years or so, thus it means we are approaching a new maximum within the early decades and years of this century.
What this entails? In previous cycles we have seen usually an increase in Vatnajokull eruptions before one or two large events occurs, this goes on for about 20 years until activity reduces again. In last cycle, we see the rifting Bardarbunga eruption of 1862 and then the large event at Askja in 1875. And a few significant eruptions in the couple of decades following.
So, it seems that the big event will be in… Bardarbunga probably. Because that’s where we keep seeing all those quakes and inflation. Hamarinn comes to my mind. Askja with something minor. Hekla too. And who knows if in Tungnafellsjokull, Esjufjoll or, Kverfjoll.
Is this that you know and you have kept in secret?
Nope, it is the inflation mode, and how the models are projected for how a Veidivötn and Laki event would look on the GPS trajectories. What I have kept secret for more than a month now is that we have magma formation along the southern part of the Bárdarbunga swarm. The vote is out for the northern part.
But I knew the other part too, the increase in hotspot activity, and also that the strain in the SIFZ is closing in on maximum. So, when I noticed the changes in GPS trajectories for almost all of Iceland (complete with a bradyseism lowering Höfn) I knew we where seeing a magma pulse forming as new magma was produced under the fissure swarm.
Where the eruption would occur, if it ooccurs, and when it occurs, that is something we do not know yet. The only thing we know is that a very large area is affected, and that it will show up all over the place, and as time goes by we will see it settling on a specific place.
And yes, there are others obviously who knew this, guess why some people are nightshifting during a public Icelandic holliday…
Wait, what? Torfajökull and Bárdarbunga before Hekla?
Considering what everyone, up to and including IMO have been saying about Hekla being ‘ready’ to rock and roll at a couple of good quakes notice…
Nah, Hekla is most likely to go off first.
But Bárdarbunga and Torfajökull are likely to go off before, during, and after Veidivötn/Vatnaöldur. The same as Grimsvötn and Thordarhyrna went off before, during and after Laki.
I like add Vatnafjöll (Lambafit) and/or possibly even Tindfjallajökull to this list of places that could go off before, alongside or after Veiðivötn/Vatnöldur events. It was during formation of Fimmvörðuháls dike in January thrugh March 2010, and afterwards, I noticed there was some quakes that possibly indicated an “lateral injection tongue” towards Tindfjallajökull.
And there is still a large question on Katla. What is it with her? She is unrealisticly quiet.
humm… we are visual on Hekla now … most of it anyways … not propethic enough to speculate but Hekla can likely be framed on circumstantial evidence
http://www.livefromiceland.is/webcams/hekla/
Oh, a small update, but it will not be anything new for the regular commenters in here.
http://earthice.hi.is/gjalp_eruption_vatnajokull_309_1310_1996
Islander, I was trying to find this website for months! Takk!
So, actually Bardarbunga had a minor explosive and brief eruption in November 1996, a few weeks after the Grimsvotn/Gjálp early October eruption.
Bardarbunga has actually erupted recently.
Was this eruption on the caldera?
Yes, I think so,
same or similar type of event that happened in Katlla July 2011, just 20-30 minutes.
“”A small eruption started in Bardarbunga around 1300 hrs on November 6th. The eruption lasted for about 20 to 30 min. According to seismograms at the Meteological office, the eruption was initiated by some intrusive activity. The intrusive activity is based on recorded eruption tremor picked up by on of the seismometers. Eruption column reached about 4 km in to the air. Relation between pressure decrease due to the flooding have been suggested as the main cause of the eruption.””
The big question is this: Katla in July 2011 had quakes, tremor, flood, cauldrons formed in the glacier, but no visible ash or steam column into the air
According to the report you linked, Bardarbunga in November 1996, had tremor and a column 4km into the air. That is more than just a subglacial eruption. That means the eruption cut through the glacier and therefore must have been large. But wouldn’t it melt the glacier within Bardarbunga caldera and crate cauldrons there? Also I see no reports of it in GVP or anywhere else in the web… Its a mysterious eruption….
Highly mysterious eruption…
The Katla one lasted far longer, and it just showed up as melt, so I think that one was just a powerfull geothermal event. No gas was released after all, and definitly no ash. I checked the satelite gas measurments for that event.
But if they saw an eruptive column… well, that is something that is hard to debate with.
it might have been right in edge of caldera, where Ice is thinnest …
I wonder if we are not going to get a stone tablet in the morning regarding this intrusion (I am not expecting any eruption stone tablet since there is no associated tremor).
no, these are just six quakes (not 60 or 600)
I meant more regarding the full picture. A tablet on the magmatic pulse.
nah, do not think they speak out, unless there is risk or something like that.
But they might throw out a news bulletin
I think they will say something soon.
Will be interesting if they think the same as we do.
I thnik they will not speak up on this, uless somthing precise happens, its “Funding” that still rules
With Carls inadvertent excursion into prophesy, I have come to appreciate, 30+ years later, my quest for females. Way back when, when I was much younger, I would literally spend the weekends camped out at the local skating rink. Skating. It got to the point where I was quite adept at it. The goal, of course, was the same as all teenagers in my cohort group. It’s likely the same as it is now. (You just have to be wary of the Cougars) There is one thing about skating, (roller or ice) and being half arsed good at it (roller for me) , your motor skills become attuned to not busting your arse. Add 20 years of riding ships and having your sense of balance reinforced on a day to day basis. You develop spider monkey like skills at avoiding eating the floor.
I’ve fallen off the back of trucks with a 300 lb copier coming down right behind me, and managed to grasp that fleeting hand hold and swing out of the way as the copier destroyed itself where I would have landed otherwise. As I noted to my boss when he inquired if I was injured… “you don’t do 20 years in the Navy without learning how to fall down with out killing yourself”
So, the other day, when Carl apologized for speaking of me in the past tense, I thought it was prophetic since that very morning I had done the one legged scootie-scoot across the kitchen floor on top of a floor mat while trying to get coffee. Spider Monkey skills saved my arse on that one also. I came withing 4 inches of bashing my head.
And today, I ran across a “doggie got to go now, eh, this is good” spot and found myself in the one legged scootie-scoot maneuver yet again. This time, “countering a misplaced skate” skill came into play and the dog got chastised for his impatience.
To be honest, during the way back when that I mentioned earlier. My friends and I found an abandoned house in a sand-pit. It had been a residence back before the sand pit property had been sold for fill-dirt. With no windows or furniture, and half a door, it was a great place to get drunk and skate around what once was the living room on the now wooden floor. I’m sure that motor skill training helped some, as we spent most of the time trying to knock each other over. I also found out that if you win, and you have managed to knock your friend over and he decides to take exception to it later, after you have your tennis shoes on, running flat out into a dead-fall is not a good idea. It took me 20 minutes to crawl up through those branches and briers. He didn’t pay me back for knocking him down while skating. He sat there and laughed his arse off at my predicament.
Okay, enough memory lane shit.
Shallow quakes eh? Ponder this. The closer to the surface you get, the cooler the crust is. Cooler crust is less mailable and responds to strain by cracking rather than bending. That 18 mm/yr (I’m 18, and I don’t know what I want!) builds up over time. As noted in “The Dead Zone” post from a while back, I think that at depth, the crust is still to hot to have many strain related quakes. (hence “The Dead Zone”). Those surface quakes may be a harbinger…. or not.
Your mileage may vary.
Is it just me or is IMO GPS reporting down? All charts are showing blank ATT e.g.
http://hraun.vedur.is/ja/englishweb/gps/predorb/skropred.html
Never mind found some of the good stuff; http://strokkur.raunvis.hi.is/gps/#CHIL
Even if these events are small, they still strike for myself. I am surprised by this sudden expression from Islander, Carl and even Irpsit.
http://hraun.vedur.is/ja/hekla/oroi_hau.html
Must be run off from all the local rain in the area.
Ah, no, from 8 to 5 midweek its roadwork in progress. Think how a big Caterpillar influences a seismometer nearby. They have one out there, I have seen it and lots of other vehicles, incluting a vibro-roller down the road. This is to last all summer.
The road works must be affecting + 30% of iceland. The same signal or even higher on some of them??
Guess why it is quiet around here? everyone is building bunkers..
Maybe blasting some rock or dam work.
No, neither. And I am not building a bunker. No need. Besides you can not move it in case of “vulcan-udbrud” (volcanic eruption).
There is Hydro-Electic-Power-Station dam work near to Hrauneyjar/Sigalda area, mostly east of Búdarháls, but it simply is so quiet it does not show on veryday bases. Even blasts do not appear anymore. The roadworks only show at HAU, as their mine is close to that place.
Some of this can be noise spring melt, when streams turn into small rivers or larger-rivers.
May and June, into July is the period for this.
What Diana and others maybe have noticed is (huge?) magmatic pulse coming under central Iceland in the last year or so, largely visible this year.. Its affecting mostly near the dead zone but also the whole central area from Hekla in west, Katla in south, to Askja in east (that the impression I get from Carls explanations – both these abowe and in private posts) and perhaps extending to Esjufjöll in SE. It also has made many the GPS stations in the central highlands reverse drift-direction. What this means is, we can get “pulse of several eruptions” is relatively short period. Think perhaps five large events and perhaps one larger than even those. *not expert, It may take years or decades to develop*
Just read on the story of the 1720s in Iceland. It was the utopian decade for volcano cafe. Eruptions nearly every year in Iceland, and one year with 3 volcanoes erupting. And some of these were big ones: an explosive VEI4 in Oraefajokull, a series of explosive eruptions in Myvatn, a large eruption of Katla, an eruption at Kverfjoll.
I recall this nice post by Jon http://www.jonfr.com/volcano/?p=765
also another pulse around the Bardarbunga dead zone eruption in 1862-1864 followed by the eruptions in Askja 1874-1875, together with every few years a minor eruption in Vvatnajokull.
Another pulse probably when Laki erupted, but that seems to have been a localized pulse or otherwise the rift fault/fissure that critically failed.
Also in the 920-940s, and 1220-1230s, there were a series of large eruptions, in what seems to have been a hotspot pulse.
To find a pattern between these is somewhat tricky. There seems to be a cycle of around 130-170 years, a very rough and variable irregular cycle. If it is so, then we could expect a new one circa 2000-2040.

Today big news, from a recently published paper:
http://geology.gsapubs.org/content/early/2013/06/05/G34100.1.abstract
“Are subduction zones invading the Atlantic? Evidence from the southwest Iberia margin”
This is big stuff. Basically, there is the early start of a subduction zone at the eastern edge of the Atlantic ocean at the southwest of Portugal, where very large M9 megathrust earthquakes occur about every few centuries. Last ones were in 1755 and back in the 1500s.
These subduction earthquakes create some of the largest earthquakes in Europe and in the world, and potentially the most catastrophic tsunamis in Europe. Its a pity that, because of such risks, this unique process is not studied by more people as it presents a clear danger for millions of people in nations like UK, France and Holland, besides Portugal and Spain.
I wonder if we could see also such earthquakes as evidence of early subduction in the east coast of the US.
The US seems more content with being shoved up over Pacific crust. I guess the Eurasian continent is just a bit to much to move.
But, I guess more and more places along the European coastline will start to have larger earthquakes as the pressure builds.
Eventually, yes. The mountains along the west edge of the Atlantic states are made up of layers of volcanic island arcs plastered onto the craton from past wilson cycles. These are mixed with fold belts of old basins that were crunched up into mountain ranges in the accompanying orogeny.
Maybe someone would like to write a post on that? 😉 I know a little on the stuff on this (east) side of the Atlantic, not so much on the possible proto-volcano spots of probable far future volcanoes in Northeast America. But I think its a cool topic to dwell into…
Sounds like something that would be perfect for Lurking to write about 🙂
I hadn’t thought of subduction as the cause for the small increase in western European quakes. I was looking at the spot near Le Havre in France which has been having quakes fairly infrequently recently. Yesterday’s was at 1 km depth. The channel tunnel is further north….
Southern Portugal has a lot of evidence of an extremely ancient volcanic past, but wouldn’t the hot spots of the Canaries and Azorres be driving some of the on-land tectonic movement?
Just looked on wiki:
‘Gorringe Bank
The Gorringe Bank is part of the ridge along the Azores-Gibraltar fault zone. It is about 60 km wide and 180 km long in the northeast direction. Two high seamounts exist: The Gettysburg Seamount has a depth of 25m, and the Ormonde Seamount is 65m below the surface. The plate boundaries here are converging at 4 mm/y, as well as sliding past each other. Upper mantle and oceanic crust are exposed along this bank. Ferrogabbro dated at 77 Ma has been intruded, Also at 66 Ma the Canary hotspot mantle plume passed by and caused alkaline magma to intrude. Where there is crust, it is very thin, so that the moho comes up to the sea floor. Sediment overlies the mantle, so this could be considered as crust. Since the Miocene there has been shortening of the ocean crust absorbed by folding, and thrusting.’

It seems like summer have hit the crowd…
Female members out in the sun, getting some nice tan?
I heard there had stopped raining in England but I maybe wrong. It has rained here fo a month now, before that it was cold spring, before that is was snowless winter, before that was autumn (that was mild or not wet). Ah, what a problem the weather is sometime.
We had a good week in Ireland and now its gone, till next year. I am around and my schizophrenia can cover the others. 🙂 So Carl the only question left is who do wish to chat too??
OT, Michelle Obama, was around the neighbor not long ago.

If Mr’s Obama ran for office in Ireland. It would cause me to vote for the first time. As an member of Dáil Éireann that is.
Well, I would not mind chatting with Michelle Obama.
But, I could do with something nice to drink from the Green Island and pretty much anybody who does not gnaw on the furniture (to early that is).
ROFL
Yepp, one of the best strips ever.
No need expose real time left, the actual countdown. Takes all excitement out the window. It took me a while realizing there might be other numbers than zero behind “Big Picture”. One wonder if this be countdown to next flood basalt event or to “Dead Zone”.
Thanks for your prophecies and ruminations Carl and team. I feel a little justified now. Nearly a year ago I posted along the lines of: “what’s up with Skrokkalda?” because I felt the monitoring station was frequently showing harmonic tremor but without any obvious earthquakes. After the various hurled eggs, tomatoes, and pumice from fellow readers ( 🙂 just kidding), I shrugged my shoulders. Now I feel a tad justified for pointing out the readings. On and off, the Skrokkalda station has shown, and continues to show, interesting results! (Flinches ready for more tomatoes and scoria cone remnants…) But since I’m about as expert on anything volcanic as a hull riveter on Titanic II, I’ll just go and hide quietly now.
No need go hiding, we are as amatörish as the common people. Except Carl of course. He is the bright guy leading the pack *not forgetting them plotters, of course*
I admit SIL readings can be deceptive. Both rain, wind and waves pounding on distant shores show up (Red is faraway shores noise, then green medium range/frequency, Blue is nearby or high frequency noise ; and all can be quakes of diffrent wavelengths)
Ah, both Volcanic and Titanc were/are about chemistry. The steel used in Titanic was too brittle due to much Sulphur content, if I remember correctly.
I just posted a comment, trying to find that mythical cyclical pattern for the hotspot, if there is such pattern. At least it has been talked and speculated about in a few papers.
Apparently, such periods with heightened activity in Iceland have occurred in 920-940 (or even around 874-940), 1220-1240, 1720s (or even decades following it), 1862-1875 (and a couple of decades after). Around these periods, there has a marked increase in both frequency and severity of eruptions on and around Vatnajokull.
It seems there is a highly irregular cycle of something like ~140-170 years, between these maxima. The new peak should be place somewhere between now and 2040.
In response to Islander
Yep – agree – but I am reasonably adept at seeing weather and other influences on the SILs. That’s why I originally flagged up Skrokkalda! Regular bursts of harmonics kept showing up despite all the other noise. It’s not so busy these days. My interpretation was deep magna movements. Carl’s comments today reminded me of it and fit well with his thesis. Yes, the original Titanic steel was brittle, as was steel used in most ships of those days. It was still serviceable stuff on the Titanic, until Captain Smith ignored ice advice and maintained a fast pace to the USA. There is not much steel (of any kind) can do when a captain drives his ship full speed into a gigantic lump of very hard ice. Rather reminiscent of a certain Costa captain 100 years (to the month) of the Titanic sinking who ignored rocks visible even on a road atlas and did exactly the same. Anyway…watch Skrokkalda!
Lets have a look at this.

Is it, that all of these stations are picking up roads works around the center of Iceland. The Answer is yes. Nothing happening at all, 🙂 Apart from all night and day works that creates these Signals.
And it is just the beginning… 🙂
I agree, though my run through the numbers came up with a different interval average. According to my calcs, we are withing one SD of the interval average, and the activity period is about 32 years once it starts.
Here’s a cutie for you: Zero miles. 😀
xxx Cubic inches V6 with chain timing belt , no need replace that every 100.000 km or so as on the rubber belt ones – *only boasting of limited car and mechanics knowledge, from crusing and even quartermile racing days long past*
My only problem right now… is that I feel like a neutered toad. (try to get that thought out of our head…)
Until that motor is set in place and the rest of the peripheral stuff is on it and tested… I can’t do squat. I have at least 3 long distance calls in my que and I discovered that I need to get the waterpump done on my wife’s car. I got lucky with that one. Heat started climbing, the AC quit (some vehicles will shut down un neccesary systems to minimize heat). I set the heater on max in order to dump the water in the heater lines into the rest of the cooling system and made it to a place I could stop and cool down. Nursed it back to the house and checked it out.
Replacing a water pump is a trivial process… but given the way that Dodge designs cars…. good luck with that. They cram as much stuff into as tight a place as possible. I’ll pay the mechanic to do it. I sort of owe that to the wife since I’ve put a few thousand miles on her car while arranging to get my motor replaced. Her vehicle is my back-up and the only thing worse than being stuck on the side of the road, is having a loved one in that position with you trying to figure out how to deal with it. I carry her as a rider on my AAA account, and that has been quite worth it. Allstate has been after me to switch to them, but since they dropped me from their roadside assistance program a few years ago, I usually tell them to pack sand. (they said I had too many tows over the year…. and at the time, I was in Jersey when my Bronco’s motor gave up the ghost. Other than that incident, Allstate is a good company in my opinion. I just don’t like getting jerked around and tend to take events like that personal.
3 liter “Vulcan” to be specific. Reportedly, these things are known to still be bopping along after 300K miles, though I have yet to get one past 240K. The chain timing belt is one of the reasons that I like this motor. To meet my needs, it doesn’t have to be a power monster, just reliable as possible. I did tell the mechanic that if he wanted to drop a 289 in there, I wouldn’t complain. (predesessor to the 302 block V8) He chuckled and stated “I’ll bet”. Though it could be shoe-horned into it, it would be a chore just to keep the rear wheels from spinning. From a sensibile point of view, way too much power. (but it would be fun… for a while) I have a deep seated fear of being stuck on the side of the road, so OEM with a reliable proven motor it is.
And well founded, you never know what you are going to run across in the middle of the night in some out of the way wooded back country area. I know of one area where for a time, there was a problem with a dog pack that had gone feral. Eventually they were hunted down and eliminated, but they had done quite a bit of damage to livestock. Then there was the story of the “Eareater” that manifested itself as some thing that was biting the ears off of 400 pound hogs in the middle of the night. Turned out to not be some back woods cryptid, but a pair of dogs.
Ah, ok, thanks. (302 Ford, 318 Mopar, 327 Chevy)
I have both eyes on certain Hattie, since that bulls eye quake yesterday.
Not in predicting mode, this likely be tetonic 😉
Hi Lurking. Seems you’re having fun there.
Lovely thing. Does it guzzle a lot ?
I’m always amazed by your V6 and V8 over the pond. Luxury motors for us in europe you only find them on top of range or sports vehicles.
When all cylinders are firing and you are not being stupid with the pedal, it’s pretty frugal, for a truck.
Europe has some of the best diesels on the planet. Unfortunately, our regulators (governement shitbag bureaucrats) won’t let the better designs into the country. If I had my choice, I’d prefer one of the high efficiency diesels.
As for little gems of power… you would be amazed at what you can find in a salvage yard. Years upon years ago, I was looking for something in a salvage yard up in Mississippi. I ran across two six pack manifolds for a small block chevy. This was time when gasoline was still relatively cheap. I wasn’t into building out street machines or even set up for it. So I focused my attention on getting away from the swarm of wasps that I had also discovered and ran like hell.
.. but, just because it’s American made that doesn’t mean it isn’t full on stupid. I stopped by the shop where my truck is at one day and Jerry had the entire top end of a motor pulled off of some sedan that he was working on. It turned out that the Northstar V-8 (much hyped in TV commercials) had it’s starter motor positioned between the two rear cylinders. The only way to get at it was to pull the intake manifold and the whole top of the motor down.
Years ago, I forget what model, the only way to pull one of the plugs was to loosen one of the motor mounts and lift that side of the engine four inches. Needless to say, that became an unpopular model.
So.. though a V-8 has got some beef to it, I will never own a vehicle with a Northstar V-8. And even though they are sexy, they still eat gas like it’s going out of style. I had an F-150 several years ago with a 5 liter. (302 ci) Loved it. But it would suck a tank dry in short order.
I have a wasp nest that have taken up residency inside my roof.
Due to our explosive start of the summer it has grown like nothing I have ever seen.
Their main highway in and out of the nest goes through the roof of my balcony. I had spent the spring cosying up the balcony with a couple of chairs, a nice little table, some flowers and had planned to sit on it with friends and guzzle a few beers.
Here comes the hitch… Wasps are as you know territorial, but for some reason never against the residents in the house that they squat in. So I can sit there without getting stung, but my friends get the unwelcome treatment. So, garden it is for relaxing with a beer as long as friends are popping in.
And no, I am not about to whack the wasp nest. As most of you know some moroon decided that it was a good idea start spreading neonicotinoid toxins to get rid of the wheat bug. And those have whacked out a large proportion of the bees (now banned in EU). But in the end the slightly more resistant wasps are the best bet of getting things pollinated. So, I kind of like the little monsters going about pollinating the apple trees in the garden. Come winter I will just board up their highway with mosquito netting and the problem will be ecologically solved next year (when there is no neonicotinoids around in Europe).
Now off to board the airplane to Stockholm… Homeward bound as they once sang… 🙂
I do not like wasps. Period.
But, Wasps are responsible for a childhood memory that comes back every time I look at the top of my thigh. There, on my aging skin, is a little round 3mm crater. A surface feature, barely noticable unless you are the owner of the thigh.
Its what is left from a scar that I had when my dad took a knife to me to extricate the wasp stinger that I had lodged in there. Wasps typically do not leave stingers… unless you smack them in mid strike… which I had done. I had mistook the thread. Dirt Daubers look like wasps, but don’t strike (typically). When one lanced me on the thigh, I took instinctive action and smacked it, breaking off the stinger. writhing in agony with the stinger still in my skin, my dad had to slice out the area of the stinger.
Talk about pain. But it is one of my fondest memories of him. I still have the very pocket knife that he used in a box on top of my dresser.
A few years back a bee colony (? ) moved in, in our roof. It was actually pretty impressive. Suddenly thousands of bee where sitting on the outer wall near an iron hook. They managed to find a way in along the rainpipes and in our roof. Because it was at the street side of our house and they kept coming in via the windows we called a beekeeper who couldn’t reach them. After that we called the fire departement in the hope they could help us. They said they couldn’t do much more than a beekeeper and they would probably migrate anyway in a few weeks(If we really wanted it they could spray pesticide which we rejected). We just had to keep our windows shut for that period. In the end they decide to hibernate here. They are still here after their third winter. Last week they came out again and I have been busy to catch bees with a mug who were trapped inside. It’s quite sad, they just keep flying against the window to go outside until they drop dead. They never attacked once but make a horrible noise.
@Carl You made me think of keeping wasps as guard for your house. They would probably very successful in distracting/scaring off unwanted visitors. Otherwise you just throw some cola or other sweet stuff over them and let the wasps do the rest.
I like hornets very much. They completely ignore picknick tables and while patrolling their territory they chase wasps away.
And despite horror stories of three stings can kill a child I personally have never heard of anyone having been attacked by a hornet. Sadly, they eat butterflies.
@Sake:
Wasps rarely go meandering into the house, bees on the other hand love doing that.
Problem with Wasps is that they are only territorial around the opening to their nest, or close to their nest. No, if you want some real bad ass protection, get geeze. Nasty buggers that will hunt people away quickly.
@Lurking:
You and my brother could probably compete on hating wasps. If he sees them he turn into Usain Bolt.
@Cryphia:
Hornets are really friendly, but the size is intimidating to say the least. I just saw a study on wasp stings. And Hornets barely register in the statistics. You pretty much have to sit on one of them, or squash a nest, to get stung.
I dislike wasps too. If there is a wasp nest nearby, then I will live in fear of it. Hornets sound like a more benign but larger version of wasps from the comments here. I don’t like flying insects too much overall.
Drat this blog system. My reply was for Expert Islander!
A Dragon edited your reply, hopefully pointing to the correct reference. 😀
Yes, got that 😉
But watch out for the tourist buses at Reynihlíð.
Every single day it seems. Even weekends too.
One little Hekla quake at 17.04 was updated in IMO system about midnight.
Not the fastest calculation of a quake 😉
http://www.vedur.is/skjalftar-og-eldgos/jardskjalftar/myrdalsjokull/
OT – From Wiki:
Battleship Bismarck hit a extinct underwater volcano when it sank,
and slid down the side.
I can only imagine “The Daily Fail” headline on discovering this :
“Extreme Volcano Surfing tested by Germans during WW2”
“”The wreck of Bismarck was discovered on 8 June 1989 by Dr. Robert Ballard, the oceanographer responsible for finding the RMS Titanic. Bismarck was found to be resting upright at a depth of approximately 4,791 m (15,719 ft),[132] about 650 km (400 mi) west of Brest. The ship struck an extinct underwater volcano, which rose some 1,000 m (3,300 ft) above the surrounding abyssal plain, triggering a 2 km (1.2 mi) landslide. Bismarck slid down the mountain, coming to a stop two-thirds down.[133]””
Cooooooooooooooool. I did not know that.
Possibly tiny quake in Hekla at 00:57 hrs, visible at MJO, FED, HAU and Jons helicorder in Heklubyggð. Size possbly just 0,2 or such. *not expert*
The weathergods really don’t know anymore what they want. Up intill now, June was pretty decent with 15-20°C, dry and relative a lot of sun. Again nearly a degree under average but after the cold spring, this 20°C is good t-shirt weather. But yesterday the temperatures increased suddenly till 30°C+ and with a lot of humidity. The news was/is people warning for heatshock because of this (nobody is acclimatised for such heat in Belgium), very high ozone and pollen concentrations. (Trees/grasses are dumping their pollen all at once). Not good weather for anyone with weak lungs. Now it is 20°C just after sunset and this will the minimum temperature for today. They’re predicting 35°C. After Friday the temperatures will be back to normal with 15-20°C with a lot of rain. It seems that we only can have extreme heat or nothing. So now I’m trying not to melt away , but I can’t really think about volcanoes and such.
23°C here right now…. (2312 local). We have a rather lost line of thunderstorms wandering around just north of the Interstate, Some of the cloud tops are upwards of 48 kft…. which is a bit unusual for the middle of the night. Daytime temps are up around 30°C with a heat stress of 33°C to 36°C. Above 37°C heat stress index, the military usually throws a Black Flag. No strenuous physical education activities.
The secret is to stay well hydrated. And if you stop sweating, seek cool shelter and water. Quickly. (provided you haven’t already passed out) And shun alcohol, that just dehydrates you faster. If you have a hankering for a fruity arsed drink with an umbrella, choose the non alcohol variety.
I know you’ve to drink a lot. The real problem is here for idiots who see the high temps and go out without enough water. For those the radio is constantly repeating to drink enough water (after warning number 10 you would think that people know it) Also being Belgium with its all time wet climate, airco isn’t standard and iIt is always very sweltering if the temps are that high. At this moment we’ve 90-100% humidity so it feels a lot warmer
The day before I went to boot camp, I was dove hunting with a friend in a soybean field, temp 98°F 85% humidity. When I got off the bus from the plane in Chicago, it was 25°F and 20 mph winds.
Rude awakening.
Where I live, a few weeks ago, it was 113. We are getting a small break, but not forever.
Hi Sa’ke. Strange weather for our parts I agree. Pollen ! now I’m sure that’s where my sudden sinusitis comes from ! Started the fan yesterday.
yeah, pollen and ozone concentrations are very high. Because April/May was (very) cold, a lot of plants didn’t start blooming before June. Now they are together dumping their pollen while normally each species has its own period.
I was outside in the countryside all day yesterday, Just warm and very humid but I never suffer from hay-fever EVER, however yesterday I was tormented by severely itchy eyes. For hay-fever sufferers everywhere you have my deepest respect for how you are having to cope this year. The very cold spring held back everything from flowering but now everything has come out together with an explosion of pollen!
So far hay-fever has not been too bad: sneezes up to only a VEI-3 😉
AAAaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaHHHHHHHHHHHHhhhhhhhhhhhhhhh Choooooooo! It’s bad! I have just come in from mowing the lawn and despite daily hay fever pill, this year is the worst ever!
Good skills Diana getting the comment to go over the edge of the comment box 🙂
WoW! What an exciting morning’s catch-up. Thanks Carl, I feel sort of Vindicated . My odd little comments about “Something happening down the west side of Vatnajokull fall into place now.
@ Lurking… Today is day for My trusty old Estate car to get it’s annual MOT test. As ever.. the night before , something had to give up. This year it’s the reversing lights. It’s in at 8.30 am so no time to spend trying to find the fuses (The bulbs are OK)
So expecting a hefty bill(Check) again. 😦
These comments above are somewhat depressing . They remind me of my mortality, as so much seems to be predicted for the next 50 years and I wont be around (Unless I find the fountain of youth).
Maybe I should try to really believe in reincarnation. Knowing my luck I would probably come back as a small insignificant bug that lives in amongst Icelandic lavas…..”Oh wow! I feel something beneath all six of my feet”…….BOOOOOOOOOM!
Time for Coffee # 2 and a dollop of anti ageing cream. 🙂 🙂 🙂
PS @ Lurking…Watch what you say about Cougars….. 🙂 Caught my prey 19 years ago …and they said it wouldn’t last 😀
@ Irpsit & Islander…… ((((((((Hugs)))))))…Just cos I love all your comments 🙂
@#$@#$ Vehicle Inspections.
I’m all for keeping a vehicle roadworthy, but I found that many times the inspection system is nothing more than a method to drum up business for gas stations. “oh, look this is broke, let us fix it or you get cited.” In other words, a scam. At least in the way it was implemented where I grew up.
I found a more insidious scam up in New Jersey. There it is actually illegal for you to pump your own gas. You have to let a station attendant do it. Ostensibly it’s because the population is too stupid to carry out this task without blowing up the station, but in reality, it’s and excuse to make a menial job that has to be filled. The state also has a thing about left hand turns… which are damned near illegal or impossible to do. Miles upon miles of concrete barricades block the median of major roadways, and at cross streets you have to use a “jug handle” in order to turn to the left. (off ramp that then comes up to a traffic light to cross the road you were just on.)
The concrete industry and unions made a killing off of that idea. Yet they still cling to sporadic roundabouts that some places (like Destin FL) think are quaint and try to replicate so they can have some of that “old world” charm. (friken posers). Last bit → It is virtually impossible to leave New Jersey without paying somebody something. The bridges are Toll… for outbound traffic only. Free to come in, got to pay to leave. Plus, you have to have a permit to go to the beach. (as one screaming german tourist found out as they dragged her kicking and screaming from the water in order to issue her a citation) This doesn’t apply in two areas… Atlantic City and another area to the North somewhere. Talk about a money grubbing state.
Good morning Diana. As to coming back as something, make sure it is something a little larger than a bug. 🙂 However do try to make sure it isn’t as a suicidal idiot that would try to run on lava!
Warning! This is from the Daily Fail. 😀
http://www.dailymail.co.uk/sciencetech/article-2343943/Dont-try-home-Video-shows-man-WALKING-ON-LAVA–scientists-explained-exactly-did-it.html
Erik Klemmetti has an article on that on the Eruptions blog
ah, sorry newAliciaby, should have clicked the link, I don’t like to look at the dailymail unless pressed into it, but this article is actually pretty good – gone up in my estimation by a few orders of magnitude. I might not dismiss it automatically in future 🙂
Hey! How are you (Newby) Alicia…I can’t get used to your new name 😀 Thanks for that link 😀 Erik Klametti does a good job of trying to educate the Daily Fail…. The Editors obviously learned something. They Must have asked him “What is lava?”
I love this quote
“A colleague stands and watches from the sidelines.”. Sensible guy…..
He had probably read the Daily Fail’s (Erik Klametti’s) answer to the question..” What is Lava?” You gotta love the UK tabloids. 😀
.
Actually, I think they have hired someone who actually knows where his ass is. This is the third volcano related article they have in a row that is not full on ass backwards. I guess they got tired of being ridiculed around the entire Blogosphere. Even the Doomsday bloggers laughed at them… And that says a lot.
Ridicule isn’t something most people like. I would see why they would try to reduce it. It is still a poor article, but at least it is an improvement over the Laacher See article.
Compared to that, anything is good… I had succeeded with transmogriphying that article out of my brain.
It was absurd. The logic behind that article was “It happened a long time ago, so it is overdue and it will erupt big again.” It was bad.
Hi Diana, I am doing great at the moment thanks. I also can’t get used to my new name either especially as it isn’t my real name but that is unpronounceable anyway for most Brits. 😀
Now you got me really guessing…..Is it Rumplestiltskin? 😀
Harðurátungunafn?
Ieuan ?
Actually it is a boys name! Blushes with shame!!!!!!!!!!!! Honest I am all woman but my Czech father spoke poor English (or was drunk with the shock of having unexpected twins) and the registrar couldn’t have been much better because on my birth certificate I have one of my brother’s names and he has one of mine on his. He was the lucky one, his name could be male or female according to spelling.
Hello Everyone!
I am just in for a quick visit.
Today I am thoroughly swamped by IRL things. This is the last week before the summer vacation starts for most people, and on friday there is the huge Midsummer Eve party. So, board meetings all day long.
I will do my best to punch in some kind of post this evening if I am standing on my feet by then.
So… If someone feels a large urge to write a post and put in I would be very far from crying 🙂
If you have one, just holler and a friendly dragon will help you.

I need to watch Hekla, Katla and Iceland in general now I have to watch the ROVs in the Gulf of Mexico…. How on earth will I find time to keep the house and garden in order? 😀
Just passed over some nice natural oil seepages 🙂
You have time now. Majorities of Icelands SIL went offline, I presume some technical glitc or a digger has severed a fiber optic somwhere in town. One possible quake in Hekla just before 15:00 hrs, only visible at FED and HAU, likely less than 0,5R if valid. Currently Rainshower is forming in Hekla area, obscuring most of it!
Earlier this season… I was fishing for Spanish Mackerel down at the quaywall down town. I had not been fishing in several years, and had taken my rig down, cleaned and lubricated the reel. I use a Penn “Slammer” solid core rod and about 400 tp 500 yds of 15 lb test. Sure, the line is a bit light, but when you tie into a Mackerel they will can easily empty a bail and you spend the rest of the time fighting to get the fish back to the quaywall for the gaff hook. Good eats if you can get one.
Anyway. Our method of fishing for them is to take a baitfish and tether it on a 6 foot steel leader with a partially inflated balloon at the point where the leader meets the line. Most of the day is spent managing your baitfish, trying to keep it from tangling with the other lines, and cursing pelicans.
This year, I landed a pelican. Reeled him in and got him up on the pier. (no gaff hook). Once there we had to hold him down so we could remove the hook. If the bird is lucky, you can set the hook before he swallows it. I got the hook out, but lose the bait fish. (pelican got that). Afterwards, my hands were covered in black goo. I figured the bird has shit on me, but it was actually oily and would only come off with alcohol. (shit would have washed off with water only).
My guess is that it was residue from the Deepwater Horizon thing… but as you mentioned, there are a lot of natural seeps out there.
Oil floats on water, Pelicans float on water. (okay, bob around on water). Want to know where the oil sheen went to? Follow the pelicans.
The largest mackerel that I have ever landed was about 35 lbs, but that was years ago. One of the odd parts about fishing there is that after you fight the thing in, occasionally some wandering tourist wants to get photographed with your fish.
Back before Ivan rolled through here and trashed the shoreline, which was later set with stone piles to prevent a nearby section of road from washing out again in the future, there was a slip next to the bay bridge (3 mile bridge) that was chest deep out about 300 yards. Great place to gig for flounder. Well, it used to be. No idea what it’s like now.
http://i186.photobucket.com/albums/x96/wildjinny/Atlast.jpg~original
Been fishing all my life.To prove I don’t come up with those fisherman… oops! sorry! fisherperson tales here’s me with a grey Mullet from a tidal riverlet in Anglesey, North Wales. ( Just behind me there is RAF Vally ,where prince William is stationed) It took me 20 years to finally land one. They are notoriously difficult to catch. Lovely fish with big kindly almost human eyes a wide smiley face. I kissed it and returned it after the photo shoot :D. Sea bass are better to eat and harder to play in. Mackerel here tend to hook themselves and I used to use them as a bait fish although many like the rich oily taste,I am not keen. Turbot are heavy, conger eels are evil and have teeth but my wierdest catch was a Ling. Big, heavy took forever to get into the boat but tasted good. Lutefisk ring any bells Carl?
There you cought me with one of the two things I do not eat…
A lutfisk (lye fish) tastes absolutely nothing except a tad of chlorine. I positively detest tasteless things. The other thing I do not eat is melons. To me they taste like swampwater.
Heck, on my job PC there is always at least 4 small windows constantly open wathing Hekla, And now I had to watch this too, … Lucily I have 2 monitors then…And the same setup on my home PC. How will this end Diana? 🙂
I advise an endless supply of Columbian Coffee and plenty of snacks and instant meals ..If things get really difficult try sniffing lavender oil instead of anti depressants 😀
Errm! Mizar just look over your shoulder once in awhile and make sure the Boss don’t see you ruminating 😀
I do 😉
How much inflation is occurring along the Bardarbunga Fissure? I have been more worried about this system since learning about a it.
A little unrelated to the exact topic
How active is the Tjornes Fracture Zone?
Is it true that most of the Ash from Katla travels north, west and south mainly? How thin or thick is it? I think it is thinner than her nearby neighbor but would like some verification.
How many people here have seen samples from the other Icelandic volcanoes?
Between 2,5 and 20 cm per year depending on where you measure it.
The Tjörness is a very active faultline, but it is not volcanically active. There are though 2 volcaning fissure lines there with submarine volcanic activity happening about every 50 or so years.
Katla ash travels mostly north, west, south and east, in all directions 😀
I mean, it all depends on the weather at the time of eruption. Icelandic weather can have consistent winds for a long period of time, or other times, very changeable winds every few hours.
For instance, now we have been having constant south, southwest or west winds.for a few days. But during Eyjafjallajokull winds were constantly from the north, blowing towards Europe. The most common wind direction is from the east.
So, if you map for instance the spread of Hekla ash of several eruptions it gives a well spread map. Some eruptions have affected mostly the north, while others the west, while others the south and a few others the east.
Thickness wise I do not know. It also depends in the interaction between old and new magma and the glacier itself. Color wise it will be dark grey to black.
If the Icelandic Low (a semi-permanent atmospheric feature) is present, then mostly ash would move away from Europe. Lately, the Icelandic Low has had a tendency of wandering off. In that case, it’s any bodies game. A large and dominant Azores High (another semi-permanent feature) would tend to drag ash down into Europe.
Move away from Europe???
Well, I guess Scandinavia and English Isles would be counted as outside of Europe since we do not produce wine… 🙂
Normally the Icelandic Low produces low pressure fronts that move in over our asses every five days. That is why you find all those nice ashes in our bogs.
I really enjoy this blog allot. Carl, maybe leave it be if no one else can blog tonight. Tomorrow is Another a day. Hope you survived the meetings to arrange more meetings.
If any is going to happen in the area of Bardarbunga, It could be decades or years, months Away. I do not know, however inflation is one possible sign of something. We all know cakes Can not be made from one ingredient alone. 🙂 Unless I am cooking, then bury that road kill Quick!! 😀
If you need a post, I can do one but it won’t be ready before next week. The last one was a bit rushed 🙂
Would love that 🙂
Just checking the picture
Well, finally home after a long couple of days…
I finally got a bit of payback on a person who spent the winter trying to stab me in the back while I was sick. Thing with backstabbing is that you should only do it if you are damn sure that you will succeed. Especially if you are backstabbing the person who got you the job as CEO in the first place.
Today he tried again at the board meeting. This time around he got the same experience as a robberer in medieval times would have gotten from trying to stab a Knight Templar in the back. First the knife slid away on the back armour plate, then he got a pissed off guy with a huge sword turning on him.
The guy had spend the last 6 months failing to get the financing for a large mining project. Very quietly me and the Chairman had secured it without telling him. So for 15 minutes he sat at the board meeting explaining that he could not get the funding while blaiming me for it, without knowing that everyone else around the table knew that there where people from the banking company sitting outside waiting for us to vote on and sign an allready done deal. I am probably a horrible person who forgot to email him the news…
In medieval times there would have been a satisfactory “Thunk!” as the head hit the oaken floor boards, but in these slightly more sophisticated times I got the personal joy of escorting him and his personal coffee mug of the premises.
Probably the first and only time I will enjoy pink slipping someone, normally I find it horrible.
Carl,
Seems as though you were completely justified in taking his “head”.
Hope the mining project goes OK
Colin
Concession permit given. So, a 3 year long process of starting the mine begins in August.
Thing that makes me most happy is not getting my little revenge, it is that I know there will be a heck of a lot of jobs created out of this.
I am more worried about the other mining company I board on, it is a prospecting company. Waaay harder to fund those.
Seems good news ! Some execs are just greedy b*****. I don’t undestand this type of behaviour. If you need some water treatment let me know !
Water treatment? I might be hard boiled, but I think water torture is a bit much 🙂
Actually, most people who make it into the boards are nicer than most people think. It is middle management guys that is a pain in the behind. Problem is just that one has to try them out for upper management now and then, most of them fail.
Now I am going to contemplate water treatment for a while. 😉
plic, plic ….
“Middle Management” aka, Department Heads.
Okay, you were not out for revenge, that makes the Karmic settlement all the more profound and enjoyable. I especially like that the group he was complaining at knowing full well that what he was flailing about was a total line of shit, fully exposed and farcical.
Sadly not with live video…
Few know that Clint is a pretty good jazz pianist…
I love this piece of music. I have heard many versions of it.
Congratulations on getting the finance.
Thank you!
And what are you going to extract ? We spoke in the past of extracting iron from Olivine I think.
That was another company. The iron from olivine company is the one spending time to mosey around the world looking for things to mine.
This is a much larger operation. It will become Swedens second largest iron ore mine and the worlds third largest underground mine.
OK, and what type of mineral do you get. Oxydes, pyrite ?
Apatite iron ore field with 4/5 magnetites and 1/5 hematites.
Ie, fairly normal swedish iron ore.
Apatite ? Phosphate ore ?
Magnetite and Hématite are oxydes if i’m not mistaken…
Are you going to build a plant to refine on site ?
It is one of our quirky magmatic iron ore fields.
And to your question. Yes, refining onsite to pellets which will be shipped via rail.
The first sample I got of Magnetite I pried off from a church wall (!) in the Ardennes’ Meuse valley (with my swiss army knife). Lovely small tetrahedron.
You little vandal you 😉
I was a bit reckless at the time I admit 😀
Another nice deep earthquake. This though is not in any way related to the activity in the SIFZ. It is just a rememberer that interesting things can happen at the right depth at other places in Iceland.

A 2.3 at Godabunga according to met office.
There is something wrong with that one. It is given as 0 kilometer depth. On the SILs it also look a lot smaller then 2.3, I think it will be reevaluated when someone more senior look at it.
I am starting to wonder how much higher Crete has gotten the last few days. This is one persistant swarm.

Hahaha, looks like there are other things then a supervolcano “erupting” at Yellowstone 😛
Seems like there have been more then a hundred eruptions at Yellowstone in the last few weeks 😉
Yekh, norovirus is not fun…
On an unrelated topic, but dealing with gastrointestinal issues, I made a pasta salad for dinner. I’m not quite sure what exactly is is, but that’s what I know it as. In my version, I have multi-grain noodles with olive oil, Italian seasoning, and kidney beans. Later, I found my wife eating some. As she was eating, I noticed that occasionally she was slipping something to the dog that was giving her the doggie mindcontrol look. you know, “feed the dog… feed the dog”
I asked if she was giving the beans to the dog, “No, just a noodle” she replied. I said, “That’s good, we don’t need any little rocket dogs running around here”
She just glared at me. 😀
Want a good prank to play on someone? Feed their dog ham cuttings with plenty of fat on them. They will curse your name for quite a long time if they ever find out that you did it. (For the sake of the dog, make sure that the ham is cooked, dogs are just as susceptible to trichinosis as humans)
I reckon Dog food manufacturers are in cahoots with Air freshener manufacturers 😀 Have you noticed it’s always the dog, not husband’s sweaty socks that sets off the automatic fragrance thingy on the adverts? Our pretty little female dog Meg looks so sweet and innocent…….in reality she is a noxious time bomb… timed to activate as soon as we get visitors :D…. can be useful though 🙂 🙂 Maybe should try her on door to door evangelicals and window sales men 🙂
When I was growing up, we had Dobermans. Anytime one of them would pass gas, my mom would whack the offender on the arse with the news paper. Over the years, the dogs developed the behavior of getting up and leaving the room when ever any one passed gas. So… if you ever saw the dog quickly get up and trot out of the room, standby, something odoriferously foul was coming.
I endured that lot coming through Paris earlier today. Truly biblical. I don’t think I have ever experienced any weather like it in Europe before.
It only cost me a missed flight and a half-decent pair of shoes, but for many it has been serious in the extreme.
** reply to Chryphia **
Today… the local news reported a car jacking. This is not normal for Pensacola. But in keeping with the shear idiocy of our criminals, he was apprehended after he abandoned the car.
It seems that he couldn’t quite grasp the idea of using a clutch and a stick shift.
Love it 😀 Here is another epic fail 🙂
Left his DNA on the garden hoe… I don’t think he had any choice in that part of it. Other than not knowing the homeowner was armed with it…
Quet day, everybody? Here finally some sun, but brought up northerles, so cold too, I call this “Window Weather” (best stay inside and watch it out the window)
Here we had a fog all day which I assume was caused by the colder air-stream coming up against the heat in France. So grey and damp. 😦
I am going to put in a post in a couple of hours…
Hamarinn has been busy and Bardabunga wants to play too!!

They must have read Carl’s Post!
Those two East of Bárdarbunga is at the same place as the emplacement I wrote about in the update of this post.
They will most likely be put in as being lower when they get around to checking them. Most likely there where a small swarm of them at around 20km depth. When I look at it more closely it was a 15 minutes long event with clear LP characteristics. There was also at least another earthquake at 17.12ish…
Clear sill intrusion. Wonder how far up it went… If the automatic solutions are the upper edge it could get interesting. Two emplacements of new magma in just a few days….
Oops, it has hammered 6 km upwards in 3 days. I guess we will soon have a swarm of brittle fracture earthquakes from 12 km upwards… This is officially the most interesting magmatic intrusion I have seen so far.
This due to it happening in an area where there should be no activity, and at a spot where there is no known central volcano, and no known fissure swarm.
My guess? Not a clue on how this could happen. Perhaps an unknown fissure swarm or something, could also perhaps be the Askja fissure swarm that reaches into there.
And here is the name for the place:
Harðurátungusprungu, but for the sake of it I think we should name it Manuél.
I’m wondering how thick is the glacier in that spot.
Hard to know, but not more than 800 meters, and not thinner than 300 meters.
So, it would be pretty ashy in the first couple of days if anything poked its head up.
It is 500+ meters thick, around that area. The Bardabunga EQ’S have change again. Now smaller, more of them and the dept too. The new SIL’S will help, I do not see them on the link below.
http://hraun.vedur.is/ja/oroi/allarsort.html
They are online Rick, just not connected to the public pages yet.
It is almost prophetic that they brought them online just in time to catch this. I am not so sure we would have been getting this kind of hard placements on the quakes otherwise.
Thanks so 500-800 m thick, than you need quite a lot to break through the ice.
Grimsvötn have done that on occasion in under 10 minutes…
Do not forget the scale on which an Icelandic eruption can be. If you light a 1280 degree torch that is about ten km long, and half a click wide under Ice you get a lot of melt, and a steam explosion that will blast the Ice apart in minutes.
Sí, Manuel is comming home…
This is a lot of knocking on the door. I think we have our first brittle quake in cool crust at 3km…

Askja wants to join the party too
It was an interesting game when it first came out.
Son of Morgenstern. Real break up at the time. Great fun to play – cheat mode included….. I played it on a 386 SX 25 (nuke powered, I live in France). completely OT, but just for the fun. A guy has reinvented the windmill (not the pre coal efficient stuff in the Nederlands of old but more like old greek design), and all greeners are happy.

Sometimes I wonder.
I find it a bit disconcerting that there are sporadic events all along the line.
Me too…
But I find the deep quakes more disconcerting. It is the first time that there have been magmatic quakes at 20km depth at two places in Iceland at the same time (Trölladyngja & Manuel).
After all, there are almost never quakes that deep in Iceland. Only known previous swarms at that depth was Upptyppingar in 2007 and Eyjafjallajökull.
And those sporadic brittle quakes at the start of Veidivötn are also interesting.
Think Iceland has measles 😕

Yepp, and of the worst case.
I just named the new volcano into Harðurátungusprungu, aka Manuel.
I understand that Fed could be broken. Is it a me thing or has a harmonic tremor been on for the last day or two. Alf sees it. As does Esk and Hvo. I did not want to spam, so just the one link below. All centered around the area near Hekla?
Eerr.. humm.. FED seem had Harmon Music Practice over ten days now (possbly power issues as it seem send info “if it feels a quake”). I expect (think) it be ready for the grand opening night sooner or later, maybe sooner. *personal opinion only, others may disagree*
Looking at my map of Iceland volcanoes saying “Holy Cow!” Getting very interesting.
OT for Lurking – the Nautilus is docked at Gulfport, MS. Maybe they need something fixed :D:
A small treat for Lurking (but I think he’s more of the “superficial” type)
Our very first nuke sub on display. I visited it a while ago.
