Te Puia o Whakaari it is called by the Māori, White Island by the later inhabitants. And it is the first correct answer to this weeks Sheepy Dalek Name that Lava XIX. The volcano whose upper part is now know as White Island is over 2 million years old. it got its “european” name by James Cook who discovered it sailing through the Bay of Plenty 1769 and it got its name because it was always covered in white clouds. He did not notice it was a volcano.
White Island is erupting quite frequently. The eruptions in 1981 and 1983 formed a crater lake and destoyed lagre parts of the Pōhutukawa forrest. An eruption in 2000 formed a new crater and covered the whole island with a layer of ash.
Today the volcano is a tourist attraction but the number of visitors is strictly limited.
Just recently the island was set to alert level yellow as you can see on the page about it by GeoNet.
3 GeoNet webcams One showing the crater; Two Whakatane; Three on the rim.
Another webcam can be found here. Images are taken every 30 minutes.
The seismometer, there called volcano drums by GeoNet. The Alert bulletins can be found here, and here is more info on the volcano.
You can book a tour onto the Island.

Pele`s Hair
Pele´s Tears.
Quote from Wikipedia: “Pele’s hair ( is a geological term for volcanic glass threads or fibers formed when small particles of molten material are thrown into the air and spun out by the wind into long hair-like strands. The diameter of the strands is less than 0.5 mm, and they can be as long as 2 meters. Pele’s hair is deep yellow or gold and commonly found downwind from active vents. Pele’s hair is named after Pele, the Hawaiian goddess of volcanoes.”
More info: University of Hawaii
Quote from Wikipedia:”Pele’s tears is a geological term for small pieces of solidified lava drops formed when airborne particles of molten material fuse into tearlike drops of volcanic glass. Pele’s tears are jet black in color and are often found on one end of a strand of Pele’s hair.”

Sweet post 🙂
Nice ! I did not knew for the tears.
should work over my irregular verbs…..
Henry from Avcan has noted today this activity.
,,Note that despite the apparent tranquility, yesterday there was one felt by the population according to IGN, but AVCAN FB reports indicate that some more have felt, one this afternoon at about 16: 15 h in the border area, in addition to noises such as a reactor for several minutes and some irritating odor (may be SO2), so that there will be that be alerts and pending the next moves of the volcanic system…. ,,

Ingrid Parparcen posted this about the noise.
..esta mañana al rededor de las 8,45 minutos hubo un ruido como de una turbina se escucho muy fuerte y duro aproximadamente media hora desde frontera
This morning to the rededor of 8.45 minutes there was a noise like a turbine is I hear very strong and hard about half an hour from border (frontera)..
https://www.facebook.com/pages/Actualidad-Volc%C3%A1nica-de-Canarias-AVCAN/163883668446
Turbine noise….
The problem is that can have a lot of different sounds. High pitched? Low pitched? Whine? Rumble?
Thank you Spica! (still not convinced about Peter Jackson, though!!!)
Someone (KarenZ?) mentioned on the previous thread about the famous Dino on the White Island webcam, so here he is on what was apparently his first appearance.
He’s still there – just check the ‘crater’ webcam.
Not guilty. Diana and Tall both mentioned Dino 🙂
* Talla 😳
WordPress just told be I was typing too quickly; they were right.
* me 😆
Thanks Spica for the photos and post.
my pleasure
Still waiting to hear how Alan and Lillith/Ishtar made out…
Alan is on holidays for another 2 weeks, I think…
You’ll have to ask when he’s back. 😉
And inform hi first, what is asked of him 😉 👿
And still nothing for Lurking for inadvertently answering the lava before it was asked.
That one was almost spooky. You answered the question five minutes before I posted.
BTW, have you checked your mail lately?
Should be an invitation there.
Some accounts alert my phone… some don’t. Mainly because because I don’t want it going off unless its something important… like work related.
At 70 mph I could care less if some Nigerian prince wants me to send money to help him transfer 10 million dollars out of the country or that seaweed helps with male pattern baldness.
I hit accept, but I have to learn the interface and the protocol requirements.
… and I’m keeping my persona. No need for a new one. It might cause issues with my other personalities. I don’t let them out.
Ding!
Then I know.
I should obviously learn to read again. I just read “…male bladder baldness.”
For anybody who believes I am patronizing bald men… I have been bald as an atomic fruitbat since I was 20 and damn proud about it.
Which riddle was it? NtL #14 i think… i ll add it after checking which one it was. I remember having it in a post but that was a while back.
Nice Olympic handball match you Icelanders!!!!! (Sorry France), and sorry for the OT;)
I generally liked the English team. Cudos for trying so hard.
Well, I guess Icelanders and Englishmen will meet in the last “group match”?
I guess the Icelanders will lay it on thickly on the poor Englishmen to give back for old grudges…
For once it will be the Icelandic Behemoth brutalizing England. It will most likely be the worst trashing England has suffered since a dude named Wilhelm knocked on the door in 1066 and said “Hello, we are the Normands, we are here to kill all your men, steal anything of worth, marry your virgins, and generally replace you guys. May you all have a happy and warm death.”
Just to make one thing clear, I will be cheering for England here, after all English beer is much better. A Bitter please!
Payback for the Cod War !! (http://en.wikipedia.org/wiki/Cod_Wars)
I’d just like to point out that the English / British absorbed the Normans. Like we did the Romans, Jutes, Angles and Saxons. The poor Normans married themselves out of existence. Even their cousins the Vikings got absorbed, too! Beware… we are quiet, be we absorb a lot. (Chuckle!)
& the Celts 😕
Since when have the ‘English’ been competing at the Olympics? It’s team Great Britain! This comprises Scots, Welsh, Northern Irish and a few English. It’s bad enough when the English call people like Chris Hoy and Andy Murray ‘English’, without other nationalities doing it too!
Very true, but why is it called Team GB, which by definition excludes the Northern Irish? Why not Team UK?
Mind you, it is funny witnessing Murray become ‘British’ when he wins, but ‘Scottish’ when he loses.
Great win for the Swedes today in the sailing, though – just sneak on through while the top two slug it out in the car park. But even better for Ainslie (that guy is just the mutt’s nuts – sails like sh*t all week but still comes away with the gold!)
I’ve wondered about the Team GB bit – but the Brits only say they are from UK when they are out of the UK! I think it’s just to confuse everyone else in the world! 😀
Thank you Spica for summarising the results.
Spica, I really like the pictures, information and references you post with the answers to the lava competition and riddles. While we all learn something in our searches, most of us don’t get the right answer so it gives us a chance to learn about the volcano and lava that are in the picture. I know that I am nearly cross-eyed from looking at the picture posted and the ones I found searching by the time “ding ding” sets me free. So now I can look at the picture with fresh eyes as I learn a little more. 🙂
Thanks Bobbi
Did you discover the answers to Alans riddles in the menu? Check under Gems.. all are there with images. Name that lava is there too but without more info. I am planning to prepare one post answering 1 riddle for each, the first on Teide is almost ready. (( This also serves as filler, when we need a new post but nothing happened in the volcano world)) I hope you like the idea.
hi everyone i am new here sorry i can’t do the links yet. the guardian newspaper has a interesting report about 15000 people died in london, due to a huge volcanic eruption in a unknow location in the year 1258. volcanologist bill McGuire qoutes biggest eruption in historic times temperatures went down 4C. backs up something happen in the 12 century.
The link: http://www.guardian.co.uk/uk/2012/aug/05/medieval-volcano-disaster-london-graves
Hmmm….he attributes it to an unknown tropical eruption but the contemporary report states that there was a north wind. So Iceland, possibly Greenland, must be contenders for the source.
Karens Yes this was a mayor bad a.. thunderstorm last night. You could see tha austrian borders in the back of the image, it hailed golfballsized iceball in Tyrol. We did not get hail but a 3 hour thunderstorm. With lightning every 5 seconds when it was worst. I always turn of everything in such events. Thats why i hit publish with the draft for this post and then turned the computer off
Yes, I turn the computer off when there is a storm and unplug all electronic stuff. Lightning every 5 secs is no fun – would give me migraine 😦
HAH!!!
Note the date: 1258
Sound familiar? No? Well, it should.
Volcanologists and Geologists have been looking for that eruption for years.
The Eruptions Blog had an article about a cryptic press release that one researcher had done that placed the location somewhere in Indonesia… but would not state the Volcano. Dr Klemett offered a couple of guesses as to which one would show up as being it, but he was just as perplexed as the rest of us about which one it actually was.
So far, the verdict is still out… but the 1258 eruption had a monster SO2 spike in the ice core record.
Has anyone considered the possibility that the reason they haven’t found this volcano is because it doesn’t exist any longer? Could that eruption been so violent that it just simply blew itself out of existence?
It’s possible. It’s also possible that it was underwater.
While the presence of a huge number of volcanoes is known about in Indonesia, many of them are poorly researched.
One should though note that they are doing a lot of research localy, and due to them writing in their own language it is a bit incomprehensible.
The Indonesian version of IMO is actually really competent, but they have a lot of volcanoes to investigate, so they are kind of like IMO, either they learn quickly or people start dying. So they learned. I respect them and their head honcho that like rock-stars and Brasilian football players only go by his first name (that I have forgotten).
IIRC, Dr K surmised it might be Rinjani which is considered to have had a very large crater-caldera forming eruption about then which resulted in the 6 x 8.5 km “Segara Anak caldera”. Even if there is no thing such as a linear correlation, as a comparison, Mount Masama a.k.a. Crater Lake, Oregon, is 8 x 10 km from an estimated VEI 7 (1.5 x 10^11 m^3 tephra = 3 x 10^10 m^3 DRE = lower-end VEI 6 really) whereas Tambora’s 1815 VEI 7 resulted in a 6 km wide crater and released 1.6 x 10^11 m^3 tephra (again, equals 1.6 x 10^10 DRE, so was it really VEI 7???). A rough comparison would place Rinjani in that range, VEI 6 by volume and crater/caldera size, possibly VEI 7.
Could this be responsible for the co-temporal deaths in London? Not very likely. Much too small, much too far away. Remember that in 1815-6, Europeans had been at war for 25 years or so and as a result were suffering from decades of malnutrion, something that is severely detrimental to our immune systems and is the main reason why the Spanish Flu killed so many just after the Great War.
“Note the date: 1258”
Not sure where you’re dragging 1815 in from? Are we talking about the same events?
Mike
I mention it should someone put forward “The Year Without a Summer” as an argument in favour of a VEI 6/7 event arund 1258 causing widespread death globally.
Mostly agree with you
Observers often use “the year without a summer” as a benchmark to make assumptions or correlations for the past. http://pubs.giss.nasa.gov/abs/st01200l.html
1250 to 1270, two decades have been cold and wet with an unusually wet summer of 1258. The eruption of 1258 was undoubtedly a factor amplifying the bad weather, but has not been the main cause of these deaths! Sorry for my English 🙂

@Stilgar
From the link that started the subthread
As for the “Year without a summer”, I believe that was the 1815/16 time-frame… and does offer a bit of disjointedness in the discussion. I don’t think people are really confusing the two… both were disruptions in the weather and both had a lot of people dieing at what was perceived to be an accelerated rate. Volcanoes have been blamed as assisting this.
Now… here is where it gets really messed up.
If you take a nice long temperature proxy… say the Central England Temperature (longest continuous record). You will be hard pressed to find this large number of abnormally cold winters. IT doesn’t mean they weren’t nasty… and if you apply signal filtering, you can pull out the deviation… but looking at it raw and in full… nothing really stands out.
The UK is a temperate climate – we don’t get very cold winters (thank you Gulf Stream). But food for thought: this year so far we have had a very wet summer (wettest drought on record) and cooler than usual ….. have I missed a VE6 or 7 somewhere 😕
Welcome Jack
To post a link just copy paste it in, the system automatically knows this is a link. And thanks for this info.
GEOPHYSICAL RESEARCH have written an article about the erruption El Hierro.
,,Monitoring the volcanic unrest of El Hierro (Canary Islands) before the onset of the 2011–2012 submarine eruption
Key Points
•Five preeruptive phases based on evolution of seismicity and ground deformation
•Earthquakes and ground deformation traced horizontal magma migration,,
The full report can be read on:
http://www.agu.org/pubs/crossref/2012/2012GL051846.shtml
Heh… It’s paywalled, but when I hit the purchase button it gave me the web version without asking for a price.
Figure 3c is an InSar pass from a satellite. Very cool seeing my technique semi validated. The negative values show the distance to the satellite as being less… inferring the uplift.
I had noted at the outset that although my graphic looked a bit like InSar, that it was not. The paper has the real deal.
Also note that the maximum seems to be out under the El Julan slide area.
Does it not seem to show also that eveything seems to be centered and spreading out from around Tanganasoga.
Dunno – can’t get the article but that would be viable from the EQ pattern.
I couldn’t get it without having to register, which I chose not to.
got it directly, no registering.
What I find interesting is the number of authors….
Cant get freeby but hers a meeting abstract here:

They recorded no tremor or lp events until the day of the eruption.
May have been a very small HT but nothing of real interest until the onset of the eruption.

Damage Control.
It’s a shipboard skill set. Damage Control teaches you what to do in order to mitigate … well, damage. How to keep it from sinking your boat or killing someone. It can range anywhere from how to put up shoring (re-enforces a bulkhead {aka: wall or side of the hull} or the overhead {deck of the next space up}) to plugging a ruptured pipe or how to seal it off.
I’ve been retired for a few years now… and the last thing I thought I would do it to put the damage control skill set to work… at home.
Sure, I’ve used shoring techniques… probably the most unlikely of the skills. I used it to re-inforce my garage door prior to Hurricane Ivan’s arrival back in 2004. It worked like a champ. It kept the tree from getting in through the garage…. though it did crush my truck.
Now… I have just used a sleeve patch on the outlet line of my hot water heater. That should do fine until I get a proper repair done.
Wootage!
Has this been published yet? Remains from a mass grave in London dated to 13th century and deaths likely due to famine caused by a volcanic eruption rather than to pest in 14th century:

Ah, and I should first read the comments before I post – just saw you already discussed this above. 🙂

@Irpsit: Could the 1258 eruption discussed above have left an ash trace or layer in your backyard?
According the Guardian article the north wind prevailed for several months, like KarenZ mentioned at 01:14. So the ashfall which hit London may have very well have hit Iceland as well. Or even originated on Iceland.
On The (ash) history of Iceland, in my backyard – Part I, Irpsit describes a “double” white band of Hekla 1104 and 1341 between the dark layers Veidivotn ash (1477) and Vatnaöldur ash (870 AC).
” At close inspection, the upper white layer (at 25cm) is actually a double of two light colored layers, while the lower at (49 cm) is a single thick layer. Obviously these layers seem to come from Hekla.”
If the 1258 eruption left some ash on Iceland, it might be present between the Veidivotn (1477) and Vatnaöldur (870 AC) layers.
Oh wow
Now this Vc project turns into a completely new direction.
So the metallic layer might be the missing 1258 eruption???
Wonder if the London 1258 ash composition has been researched. The ash simply must have left a (maybe thin) layer there.
MIght be difficult to find enough undisturbed land in London to find good evidence of ash. Unfarmed & uninhabited land elsewhere in the UK might be a better place to try.
The morbid researcher… would exhume the bodies and do chemical analysis of the chest cavity/esophageal/sinus area to look for evidence of volcanic ash. Undisturbed graves would be required since the soft tissue has likely decomposed and the position of the sample in the grave would be the only indication as to what part of the body it came from.
But… that would only be for the very morbid researcher, after he/she convinced the court system and the local populace that it was really important.
People have been hung for less.
Loads of graves from that era that is legal hunting ground as soon as you have a permit for an archaeological excavation.
People tend to not give a crap if the dead person is 800 years old.
Seems like your dead body is better protected in a 800 years old mass grave than in a 30 years old grave in a regular churchyard.

August 5, 2012 at 20:26 (Edit)
Unless he’s a 9,300 year old specimen that may go against the political claims of “Native Americans”
In order to keep further study of Kennewick Man from proceeding, access to the remains have been restricted by the court system. If he turns out to have distinctly European traits or genetics… that would sort of upset their apple cart.
I’ve posted elsewhere about odd Haplogroup X distribution.
Hi GeoLurking, the law is different in Britain. A licence can be obtained if human remains are likely to be discovered during an archaeological excavation, or if discovered unexpectedly, the licence can be issued retrospectively. The remains (usually skeletal, but also cremated – usually Bronze Age or Roman) can then be excavated and studied for the archaeological knowledge. The vast majority of people in Britain are happy for this to continue. There is a very small minority who have taken a leaf out of the American book and talk about their “ancestors” – usually in relation to anything found at Stonehenge – and demand “their ancestors” be returned to where they were found. Unfortunately for them they cannot prove that the remains are “their ancestors” and not, for instance, the ancestors of the archaeologists who dug them up, or anyone else for that matter. Also they do not mention the huge number of “ancestors” found on the sites of numerous housing estates, industrial developments, inner city redevelopments etc. all over Britain. Most people would be rather upset if presented with a box of bones and a chanting ‘Druid’ who demanded they re-bury the bones in their back garden as that was where they were found during the construction of their brand new house! 😀
Hm, not sure if ash could have actually come to Iceland from the equator in amounts large enough to be detected? As Irspit said, sometimes even the near-by volcanoes leave no trace, since the amount of ash blown that way is not large enough. E.g. like trying to find a visible trace of Eyjafjallajokull in central Europe, was there enough to build up to anything on the ground and not just in the atmosphere (most likely not)?
Anyway, there was a lot of sulphur in the atmosphere in 1258:
http://www.sciencenews.org/view/generic/id/341497/title/13th_century_volcano_mystery_may_be_solved
According to Erik Klemettis post on February 8 2012, ash particles have been found on both poles, but maybe it is still far to little to create a visible layer on Iceland or in the UK.
“First, I should discuss a little bit of the evidence for the 1258 A.D. eruption. As mentioned above, there is a record of increased sulfur and ash particles in ice cores from both the North and South Poles, along with other places such as sediment from Lake Malawi (Emile-Geay et al., 2008).”
http://www.wired.com/wiredscience/2012/02/the-mysterious-missing-eruption-of-1258-a-d/
Reading the article again, it’s not clear how the link is made to a volcanic eruption except for the [approximate] date. Could just have been the jet stream in a different position reducing temperatures (e.g. it has been unusual far south this year; heavy rainfall and low temperatures have raised the question of loss of crops. But now we import a lot of food).
The monk’s account was: “The north wind prevailed for several months… scarcely a small rare flower or shooting germ appeared, whence the hope of harvest was uncertain… Innumerable multitudes of poor people died, and their bodies were found lying all about swollen from want… Nor did those who had homes dare to harbour the sick and dying, for fear of infection… The pestilence was immense – insufferable; it attacked the poor particularly. In London alone 15,000 of the poor perished; in England and elsewhere thousands died.”

Be interesting to see what contemporary accounts exist for other parts of the country and also to have more info from the archeological study itself.

Typically the webcams are “Error 404″… Btw, welcome Jack. Is Jack = Jack@Finland or unrelated?
Is that link safe?
Ahh, it looks like Puyhue Cordon Caulle has had a larger than normal explosion.
False news!
Really?!!!
Well.. the last VAAC from Buenos Aires is 02 Abril 2012 – VAA 1400 UTC
If it’s “larger than normal” I would think that the VAAC would be on it like stink on … well, they would take notice.
Not necessarily false, that article may be from May.
Hello Jack, you know the internet is filled with places where people are rather “excited”. This is one of the least excited places on the internet. Most people here go by the official scientific bulletins.
We of course also ponder for hours above the actual raw data that we can see like seismometers, earthquake data, gps-data and so on.
But, we tend to avoid the more excitable sources, mainly due to us normally have a better clue about what is going on, than they do.
In here we have geologists, experts on plotting, and a bunch of people who is fairly good at interpreting the real data. So, on occation we see things before even the experts. We do this through using thorough scientific methods.
Welcome to the crowd by the way!
Just wanted to give you a heads up on the general level of the place.
/VC
Oh, I forgot the general nuttery that goes on inbetween exciting things happening.
Do not be surprised about the OT topics that jump up now and then… Normaly either hilarious, or informative in totally different ways. Do not be surprised if you see a plot regarding nativity crossreferenced against beer-consumption during the year.
Gimme time and I could probably come up with it.
You see Jack, I told you
Don’t forget the 9 month lag…
Look, I already posted the Bust – Waist – Hip sizes for a 3800 year old Old Babylonian goddess (Ishtar/Ereshkigal/Lilitu). Using today’s standards… she would be considered… “stacked”
The Image that Ursula posted as support for your thesis was… Well, “Inspiring”.
There used to be a visible surge in natality around the month of May (guess when is my birthday ?) as most french people took their holidays in august. Now the trend is not so clear probably because of the RTT (réduction du temps de travail)….reduction of working time
In Sweden it is nine months after the end of June…
Midsummers eve. Almost all of those pregnancies are unplanned… For those who do not know it, it is the time of year when Swedes drink waaaaaaaay to much and boink in the bushes.
unrelated btw thank you Liet kynes nice to be here
Hello Everyone.
My 2nd Issue of The Bulletin of World Volcanism is out now. Its free to download just send an e-mail to Bulletinwv@hotmail.co.uk with ‘Obtain Bulletin’ and the special code ‘M4RBVS2’
I’m am doing this for free and its not for any personal gain.
Highlights include the ‘guess the volcano competition’, this months volcano analysis and my interview with Mike Lyvers from Eruptions blog.
What the heck are you talking about? “Special Code”?
Very cloak-and-dagger!
If it’s free just put the damn thing on the web and post the URL.
Mike
You never talk here. Lucas does ads for his bulletin. Yes, noone feels disturbed.
So leave him be. Feel free to join our friendly banter, but stop attacking people
That wasn’t an attack; if I attack someone they know them. I was perhaps insufficiently nuanced, as GeoLurking put it.
I don’t usually wear out my welcome this fast. My apologies; I’ll continue to lurk and won’t trouble you again.
I’d prefer you speak up if you have anything to note. Other opinions are always welcome… besides, I need someone to serve as an equally blunt personality. About the only time I come unglued is with stuff counter to common sense.
But… I have managed to temper my abrasiveness. Some what.
Ok if it as not ment as an attack, fine sorry. i appologize for thinking so.
Lucas has asked permission to promote his bulletin and he always sends it to Carl first. He may ad it here. Some of t he dragon community think it would be better if he made a webpage explaining what the bulletin is about and have people sign up to it from there, but thats up to him.
We like to discuss here, often very contraversionally, 😉 so please stay and join the banter.
I’ve seen him talk on occasion. He has some insightful info. I thought it was a funny conclusion and response.
BTW, “Mike” is one of the cross visitors from Eruptions. I’ve been reading his input across all three of these blogs for a bit over two years now.
Hello Mike!
Lucas has kindly asked permission to plug it, and the code is just to avoid spam.
So, no need for harsh language.
Apologies to all, it wasn’t intended to sound exactly harsh, more perplexed as to why you would want to email the thing rather than simply putting it on the web. Maybe some dark suspicious corner of my subconscious pinged as an attempt to harvest email addresses! But not my business, no harm no foul 🙂
Its just to protect from spam. If you need to vent your fustration, please feel free to do it in a kinder way.
Like me, Mike is not a “nuanced” person. We tend to state what we want to say without beating around the bush about it.
No need to infer meaning or context to find some underlying reason for the statement. While you have permission (as stated by the dragon master) to make the reference and link… I have to agree with Mike about the methodology. That puts me in the minority point of view … but it’s my opinion.
Things that piss me off… inadvertently soldering a wrench to a pipe.
We are going to do it differently from now on. We do work at making as many people as possible happy. So, no more plugs, but a permanent link instead.
We just have to finnish deciding how to go about it.
Have you checked your mail yet?
I thought I had answered it.
Let me go check it again.
No nothing new. Just the original message that you told me to check for. I hit the accept link yesterday and responded via the original “did you check your mail” posting.
Just saw it…
Starting to be a bit demented here. So I forget to check things.
Think I really need my wife to come back home.
I’m a Scotsman. In Scotland we have a saying:
“The English are famed for plain speaking; they say ‘call a spade a spade’. Us Scots are even moreso; we say ‘call a spade a bloody shovel!'”
Apologies again if it came across as harsh.
Thanks Mike, a very understandable explanation! One of the many things we learn in here: we all (many nationalities) use the English language in a different way.
@Jack, I would like to point you towards the two articles about two of the 3 neapolitanian supervolcanoes. You can find them by googling Ishcia + volcanocafe and Vesuvius + volcanocafe.
I will do Campii Phlegrei in a little while when I get my energy back up.
I want to know if that is Jack@Finland.
If so “Hi!”
No, it seems to be an unrelated Jack.
We seem to be a 2 Jack crowd now.
Well, that’s cool. With two Jacks we can get the front end high enough to drop the transmission and leave the car in the driveway as a permanent fixture.
(note: the “car up on blocks” in the front yard is a redneck slam. Being a redneck, I can make the statement with out fear of ticking someone off… I have had vehicles up on blocks in my driveway on many occasions. The difference is that I actually fixed what I was working on and put the vehicle back in service. The one time I didn’t, I stuck the transmission back on the engine and had it towed to a shop. It was too flipping cold to be rooting around under the truck with numb fingers. Once I started feeling warm I figured that I had had enough pre-hypothermia activity.)
Hmmmm – 2 Jacks. I was thinking it is a good start for a pretty good poker hand.
Well… it could be worse… Aces and Eights. “Dead Man’s Hand”
You might win, but with a bullet in the back of the head it doesn’t do you much good.

Lurking, is there anything you DON’T know? Or are you just really good at “bluffing”? 😆
I get bored a lot… so I read and study the arcane. One trait I have picked up is to retain tidbits of info… or to at least be able to clue in to details that most people miss. It’s best to know a little about a lot, than a lot about a little. I’ll study the crap out of something until it bores me then I’ll move on.
Standing deck watch with me at 3 am was always enlightening for my fellow watch standers. It kept us all alert and not drowsy.
Still about 1258 Mystery eruption: At first, I also had thought that the ashes from this eruption could have shown in Irpsit’s dig, but one thing is to have ash accumulate under pristine ice and another is to have it accumulate over exposed soil. So, I didn’t mention it when Irpsit first posted.
It is of course very important how far from the mystery volcano Irpsit’s backyard is located! If it was Katla, there might be a nice, thick layer in his garden.
But I think Katla’s ash does not chemically match the 1258 ice cores from Antarctica/Greenland. If you check Erik’s article above no known volcano’s ash matched so far, until the French geologist showed an almost perfect match at the recent conference (and sparked a controversy by not wanting to disclose the name of the volcano).
More OT nuttery ahead! See the new, revolutionair grenade fishing method from Russia:
http://www.liveleak.com/view?i=4cf_1343665540
Hmmmmm! The explosion began before the grenade dropped into the water….and what happened to the second man in the boat?
I think this method for fishing is a little extreme. I must confess my attempts to land a mullet lasted for nearly 20 years and at times I did contemplate dynamite but I had difficulty obtaining it!
Have you tried a cast net?
As the mullet run down the quaywall just toss your net in and haul ’em up.
The more entertaining way of doing it… is to treble hook a live Menhaden under the spine and let it swim around out in the bay on a five foot steel leader and a partially inflated balloon at the point where your line hooks to the leader. That keeps the Menhaden up near the surface where the Mackerels can get at it.
When they hit, get ready for a fight. I’ve seen ’em empty out a bail on a 200 yard dash once they realize that they have been hooked.
I think our mullet are different from yours… we have a grey mullet that lives in harbours particularly but the Mullet I go for is an estuarine Mullet and grows much larger. Very difficult to catch on rod and line… I eventually caught one with a little bread on a fine hook and absolutely nothing else.. not even a tiny pellet weight…… hence it took me 20 years of trying as it’s not usual to use such a very simple rig and it took me that long to fugure it out!
Ps I put him back straight after the photo-call! They have such pretty, smiley faces I didn’t have the heart to eat him! ;d
The Australian Mullet is another kettle of fish; seedy, thin and altogether unappetising:
The grey mullet is very difficult to catch. My hubby used to cheat and as they swam up the channels to the river when the tide was high there came at time when the tide turned when they began to float backward. He used to tickle them like a trout, and when they went into a trance like state he would just flip them out. They taste a bit ‘muddy’ though compared to most sea fish so he always used to put them back in as I far prefer the sea Bass he used to catch on rod and line.
You could have probably landed a mullet quite easily here!

Oops! We’ve already been there, done that, played the game and watched the video, sorry!
AHHHHH! This brings back memories…..There will never be a male hairstyle so evocative of an era!
Funny innit? First cab off the line was a Mr David Robert Hayward-Jones in 1972 but it wasn’t until a decade later that it caught the public imagination…
A Quick mention. Hekla’s strain meters have been scaled down but what shows is an interesting “pulse”, a pattern of increasing strain. The lower scale shows that the increase is not even, it rises then relaxes but not enough to fall much, then along comes another “Squeeze”. I don’t think I have ever seen this regularity in Hekla before.
http://hraun.vedur.is/ja/strain/1sec/index.html
…..and so to bed. Shleep well everyone, or have a happy productive evening.
I have never seen so little Hekla motion.
It is like it is sleeping.
Ah! That’s what it is… gentle shleepy breathing.
Wow…. just… wow.
I’ve done a bit of numerical stuff with actresses and model statistics, and come up with a pretty straight forward way of calculating what the “normal” bust size should be given the waist hip and weight of the actress.
Run across the sample population, about 53 of 230 probably use some sort of augmentation. Remember, these are women who seek the public eye and do whatever it takes to stay in the public eye. My criteria was for bust measurements in excess of 3% of what the formula calculated that it should be.
Given that…. Ishtar (from the Burney Relief), probably had implants. (110.0%, or 10% over what her other measurements indicate) I calculated her weight (52.9 kg) from the Hip and Height estimates, and for height, I used the population average of 64.7 inches. (164.3 cm)
I’m not gonna post the suspected augmented group… I don’t want to get sued.
“I’m not gonna post the suspected augmented group… I don’t want to get sued.”
You probably will, Lurk. Beware the angry gals!
🙂
It’s rather funny, isn’t it…
A manufacturer who inaccurately declares the constituents of his wares can and will get done for misleading advertising in most countries whereas a woman can deliberately falsely declare and mask her true genetic value by way of implants, cosmetic surgery etc.
The one a crook…
Henrik, have you not by now discovered that women per definition is always perfect and totally without guilt whatever happens?
And if a women is suspected of not being the above, it is always we men who are at fault in the end…
Carl, educating those who are my elders here.
§ 1. The Boss is always correct. As regards intraspecies interaction, the female is to be understood to be the Boss.
§ 2. Should that not be the case, § 1. immediately supersedes this and any subsequent paragraph.
Meanwhile back on the Canaries… Restingolitas show high content of uranium & radioactivity: http://www.diariodeavisos.com/2012/08/04/actualidad/las-piedras-de-la-erupcion-herrena-de-las-mas-radiactivas-del-mundo/
Besides La Palma, La Gomera is ablaze: fire has reached the National Park of Garajonay and that’s precisely where all communication towers are located. If the fire takes them out: incomunicado.
I wonder how those fires affect the GPS and other seismic equipment…
Those fires… The slopes of Etna are paying their toll too…
If the seismo is in the fire.. not well. Same for the GPS station. Typically, the seismo itself is somewhat protected by the way they are set up, sometimes a hole with a slab of some sort to allow coupling to the ground, then covered in order to lessen external effects. But the communications side of things is exposed to what goes on on the surface.
GPS on the other hand, requires a clear view of the sky.. or as clear as possible. That means that the sensors are more likely to be affected by fire or smoke. Smoke will have a similar effect to what clouds and inclement weather provide… which is a cluttered path for the signal to pass through.
Now… as far as the other islands go, it depends on whether or not they rely on that communications tower.
El Hierro likely has all it’s data collected locally on the island, so it’s a matter of getting to the data for researchers elsewhere.
I thought the GPS data are measured against stations on the other islands as well – in which case things do become more complicated.
If all communications would go down, there’ll be a heck of a problem to coordinate any rescue missions.
VHF marine is good for about 50 miles, HF even further.
Most search and rescue vessels have a rudimentary DF capability, they are able to cut a bearing off of the distress signal and localize the position using cross-fixes. If you look at many commercial ship photographs, you will notice a single loop on a stick somewhere up by the bridge… that’s for doing that sort of thing. It’s crude, but it works.
On the other hand, I don’t even know if they teach that skill set anymore.
They are compared to other stations, but the position of the individual sites rely only on the satellites.
The only time when this is not fully true is when differential GPS is in use, in that case a reference signal from a land based station is used to narrow down the error. This really only applied to the Canadian and US systems to help overcome the lower resolution signal (the unencrypted one) that was available to the commercial market. Any GPS/GLONASS system can be augmented by a surface based reference signal if the system is specifically set up for it.
Well… the “7 minutes of terror” is tonight. 0531 UTC, 0131 EDT. In other words, in a little over an hour.
http://www.nasa.gov/externalflash/mars/curiosity_news3.html
Ding! “We’re on Mars again!”
Well, they made it.
1st two images.
And much hootin’ and hollerin’
Now… the part that I learned… this thing is farking huge compared to the other two rovers. That’s why they put it in in such a complicated way. Rather than bouncing across the surface they dropped it in with a hovering platform via cable.
Now… the amazing part… and the part that impresses me. It was autonomous.
Due to the distance, it takes about 14 minutes for the signal to get here from there. That means that you don’t have any real time control over the various systems and stage activations. It all had to be done by computer programing with sensor input and adjustments, all governed by the programing.
The control room, where all the hooting and hollering was at… essentially was there for the ride. All they could really do was to monitor the events and hope to manage it via telemetry… from 14 minutes away.
A few years ago, DARPA did a contest… one of the Darpa “grand challange” events. Who could design a vehicle that could navigate a several mile log course through desert backroads all by itself… and if successful, the fastest.
To do this, the system had to view where it was on the road, and to pick a best route to get from waypoint to waypoint. most chassis were based off of cars/trucks, but one was a motorcycle.
Due to the distance, it takes about 14 minutes for the signal to get here from there.
Yes, that’s why you have to have everything autonomous. And that’s why all the science fiction movies that show direct communications with Earth from manned space-crafts somewhere beyond Jupiter show a total impossibility.
Some of the DARPA vehicles. All autonomous. (*except for that safety truck behind the red humvee)
Morning Everyone
Dont think recently there has been an earthquake so far North in the Atlantic near Tenerife before?

Interesting again someone has noted on the Avcan Facebook page they are feeling movements.
,,22:15 movimiento seco, corto, arriba y abajo…
22:23 movimiento seco, un poco mas largo… arriba, abajo, hacia los lados
23:41 es la hora en la que escribo, y se notan vibraciones de vez en cuando desde la ultima hora que les relato.
Translated
22: 15 movement dry, short, up and down…
22: 23 movement dry, a little longer… up, down, sideways 23: 41 is the hour in which I write, and noticeable vibration from time to time since the last time story it.

For those who are interested in more unusual earthquakes. This one was smack bang between Denmark and Sweden.
A while ago we had a discussion about where the next above 6.5M earthquake would happen. I guessed at the subduction/strike-slip fautline that runs from norway down between Sweden and Denmark. Well, I was only of with strength. Instead of getting the expected 100 year event we got a 10 year event with a 4.4M.
http://www.emsc-csem.org/Earthquake/earthquake.php?id=280740
Now I will get thrown into the spam box…
Nope, I got away with an EMSC-CSEM link… 🙂
For those who are wondering…
The atlantic crust pushes against the English and Danish Micro plates. These in turn are pushed down and under Sweden creating a subduction zone. Up in the north the subduction zone as we are being directly pushed into Finland is on the eastern side of Sweden. The northern one is a mountain building major subduction zone.
In the end the Scandian mountains (old and very very hard mountains) do no budge, so everything get pushed in under. Problem is just that it is a rather small plate compared to the large atlantic crust, and the huge eurasian plate.
So, all energy can’t go into the Scandian mountains running over Finland since Finland is a part of the Eurasian plate. In the end we get squished like a wet soap northwards to.
Current motion visavi Finland is 1 cm east, and 0,5cm north per year.
That is why we have all 3 major versions of quakes in the same two major faultlines since the motion is in x,y,z direction at the same time.
Only odd thing is that we do not get more large quakes than we normally see. I guess that the x,y,z motion releases the energy in so many directions that a large energy can’t build up. But we can get earthquakes up above the 6M scale. Last was at the Weather Islands outside of Gothenburg cirka 100 years ago. But, a 1000 year event could probably pass the 7M barrier.
Here you can find more data.
If you look at the small map you can see a just a few quakes at the faultline responsible for todays quake, it is less active than the northern ones, but generally only have medium sized quakes instead.
The northern faultlines are interconnected and much more active. If you click on the map you get the last years quakes in higher resolution. Site in Swedish, Giggle-translate at your own risk.

Interesting. Haven’t found the English Danish microplate (Bing keeps finding dinner plates instead 🙄 ) but I have found old volcanicity in the North Sea:
http://en.wikipedia.org/wiki/North_Sea_Geological_History
& Oslo may have had a mantle plume:
http://www.mantleplumes.org/Norway.html
And do not forget the massive upwelling that took place through the scandian mountains as the Kirunawaara orebody was emplaced. The pure scale of it is indicative of a mantleplume of very deep origin. Should probably be called a core plume judging by the emplaced material (ultra pure magnetites and hematites).
Sometimes I ponder if that is not the starting place of the Icelandic hotspot, next stop over where it pushed through would then be the Siberian Traps with the almost equally massive Norilsk deposite. But this is pure speculation on my part.
Be as it may, the Kirunawaara emplacement (and eruption), is most likely the deepest originating magma on the planet that we know of.
Hm, wasn’t Fennoscandia on the equator about 400 MY ago? 😉
Must be north of the London-Brabant massif. But have to check it out later.
As far as I know they are two different small plates. The Danish is partialy fused to the Eurasian plate.
I thought it was the Avalonian microcontinent, squezzed between Baltica/Laurentia and the rest of Europe. But Avalonia doesn’t really reach up to Kattegatt.
Hello Everyone. I’m still thinking about the ‘supposed’ large eruption of Puyhue?
Anyone got anymore data?
Since VAAC did not register it, nor increased the alert level we can most likely write it off as bogus. VAAC are very diligent you know. And they use satelites massively to look for anything even remotely looking as ash, gas, or anything other that points towards an eruption. An Puyehue is defintly on their “check once an hour” list.
@ Carl
In other news (and I think better). There was an eruption of White Island volcano Yesterday: http://www.geonet.org.nz/volcano/alert-bulletins/archives/2012/aug-6-2012-5-30-pm-white-island-volcano.html
This is the first eruption of White Island since 2001 and the first eruption of a New Zealand volcano since the phreatic outbursts of Ruapehu in 2006 – 2007.
Also Carl you should have a couple of emails
Erik Klemetti has a post on White Island today: http://www.wired.com/wiredscience/2012/08/how-dangerous-is-visiting-white-island/
& also this one on Tongariro:
http://www.wired.com/wiredscience/2012/08/possible-eruption-reported-at-new-zealands-tongariro/
Lucas,
Shérine posted on FB an article about the re-mobilization of ashes that occurred at Chile three days ago, but there were no signs of activity from the volcano. Weather conditions contributed for ash dispersal.
The news that mentioned the eruption was from last year.

Underwater Volcano Found off West Iceland?
A mountain which the Icelandic Marine Research Institute (Hafró) discovered on the ocean floor west off the Snæfellsnes peninsula in West Iceland during an expedition earlier this summer may turn out to be a previously unknown volcano.
A fishing ship with Snæfellsjökull, the glacier-covered volcano on the tip of Snæfellsnes in the background. Copyright: Icelandic Photo Agency.
“Multi-laser measurements […] revealed a large underwater mountain deep off the foot of the continental shelf approximately 120 nautical miles west of Snæfellsnes,” a statement from Hafró reads, according to Fréttablaðið.
The mountain, which is at a depth of 950 to 1,400 meters is around 450 meters high, similar to Ingólfsfjall in south Iceland. However, it extends over 300 square kilometers, which is ten times the square measure of Ingólfsfjall.
The shape of the mountain is very similar to that of table mountains and it appears to be geologically young.
“The analysis of a rock sample from the mountain will determine whether this is the case or whether it is a volcano connected with an old drift belt, which might mean that it is 20 million years old,” the statement continues.
During the expedition multi-laser measurements were made between West Iceland and Greenland to map the shape of the ocean floor in these commonly-used fishing grounds and explore the environment of powerful ocean currents.
A total of 9,000 square kilometers were covered during the 11-day expedition.

Is this the same one that was discussed here on 3 August?
Yes.
What shall we call it?
I think Carl leiðtogi okkar which means Carl our Leader in Icelandic

erm… *coughs* Lucas *coughs*
@ Bruce Stout: Erik has asked about your whereabouts in his blog. Maybe you could tell us more about these two eruptions in NZ. Wow!
There seems to be eruption confirmed also at Tongariru: http://www.radionz.co.nz/news/national/112587/tongariro-erupts,-threat-warning-issued
Sorry, typo, Tongariro.
And it is confirmed here too… 😉
omg .. what’s that axiom from John Seach, volcanoes always erupt at the wrong time or something? This is really exciting news. I wanna go home!!! .. 😦
Well Bruce, you know what the old adagé is…
“Shit happens!”
I also want to go there.
far out, it’s all on at once. Geonet also saw a small eruption at White island over night.
http://www.geonet.org.nz/news/alert-bulletins/
key word: small
PS, if you ever want a bed in Auckland or Rotorua let me know.
I will 🙂
P.S. We have moved over to the new post! D.S.
this looks like a tiny, tiny eruption but it could herald a return to regular strombolian activity (but might not ;-)) like we used to have at Ngauruhoe in the sixties and seventies, or a resumption of growth as the conduit is now clear. Groovy. All those who managed to do the Tongariro crossing can think themselves lucky.. might be a while before it reopens!
Thanks Renato, we two should write a book one day, or share a meal or something..
A book? Yes, I can imagine the subject – some hard core tectonics.
And the meal? Of course, Salmo trutta!
Well, it looks like they dry spell is over…
El Hierro has been taken down to green alert.
,The address of the PEVOLCA States the green light, normally in a situation of early warning phase, in El Hierro
06-08-2012… 14: 35 – Directorate-General for security and emergency
From 16 July last the magmatic process registers low low magnitude and seismic activity
He has decided to address the Plan of Civil protection by volcanic risk (PEVOLCA), in the early hours of the afternoon today, to end in the affected areas of El Hierro (both terrestrial and marine) phase of pre-emergence in alert situation (yellow light) and declare the phase of normality in situation of early warning (green light). This decision is made taking into account the behavior of the magmatic process in recent weeks.,,

What is happening to the weather this year .
Just watched the news for Yorkshire over the weekend Hail that big it showed someones back yard that looked as if it was full of snow.
Yorkshire also had a funnel cloud which it said was not known to the UK and Bradford had so much rain the cars looked like it said as if they were white river rafting.
I personally cannot remember seeing anything like this in August before.
Funnel clouds are actually quite common in UK – but they are dramatic enough to get reported if someone takes a photo. Cloudbursts are also common in August – think of Boscastle a few years ago. I was in Pembrokeshire yesterday and the national news reported flooding – but it was just a big old thunderstorm and the usual trouble getting surface water into the drains. The uncommon rain was the amount we had earlier in the year – this week is not at all unusual for the time of year.
The weather is not unusual. Humid weather and storms are very common in the UK in August.
The UK also has the highest number of tornados – fortunately they are mostly very small ones.
New post is up!
Seems like the latest post has stopped updating. I published seven minutes ago and it does not show.
Here is the link.
