Sheepy Dalek – Name that Lava IX

Part nine of the volcanic trip around the world.

This week’s competition

This week will be the name of the volcanic system (1 point), and the lava (1 point) and just for fun, name of the bird.

The Score is:

3 Diana Barnes
3 Lughduniense
2 Talla
2 Ursula
2 Doug Merson
2 Hattie
1 Schteve
1 Jim
1 Luisport
1 Heather B
1 Birgit
1 Jamie
1 Henrilerevenant
1 UKViggen

This week I will not give the answer for 24 hours since people wanted longer time to try for themselves to make it into a learning competition for themselves. I will though of course award the point to the first correct answer given.

There has also been a few questions about the time of when I publish this. There are two reasons for the time, one is actually my convenience. But the other is the more important really, it is the time when the maximum amount of readers are online. There is a large peak starting when I post, and it then goes on that high for a few hours. So by using this time I maximize the amount of people that can answer. I know this is a bit unfair for some, and in the future I might put in a “night-time” competition.

  1. Hello all, can anyone else get the Iceland Mila cams at the moment. It seems for me not one of them will load.

      • Congratulations on getting the top spot!

        I have not been able to get any of the Mila cams to load this evening. :(

        • Thanks for the answer Karen, you have put my mind at rest. My son had been doing upgrades on the laptop for me and I worried it had affected the link to the cams. Looks like patience is in order then.

          • Should perhaps drink more coffee – lots of typos: alsways should of course be always, and then “east or west”. Sorry. :oops:

  2. Good morning/day/evening ;)
    They caught themselves another moonie over at Eruptions, I first tought, could someone point them to GeoLurkings post, but then on the other hand. Nah. Then the guy might pop in here and i might have to breath fire again.
    Etna and Iceland appear quiet. El Popo seem to emit lots of darker ash but only occasionally, visibility is zero on 3 of the 4 cams. Kizimen is smoking. Sakurajima is emiting ash too and this time in the direction of the webcam.
    (You can find the cams in our crowns nest, webcams)

  3. Good Morning! As you know I am prone to writing deep philosophical thoughts and ruminating about the sad state of the world especially on a Sunday.
    Why should today be any different?
    Ah! Etna and her paroxysms…………This kindly borrowed from The archives gives an insight into the dangerous missions scientists undertake for our enlightenment……I now know where Carl, Alan, GeoLurking and the sheep have been since Friday night.

  4. I do like popcorn. And I have put out VW microbus before. (not as easy as you might think… when the block is on fire)

    I have spent much of the weekend fighting software, collecting Tephra geochemical lists, figuring out how to use the software, making gumbo, watching the grandkid’s dog do the oddest thing… shell a peanut and eat just the nut, spitting out the husk. Loading the dog up on peanuts (it was a neat trick) and basking in the vitriol from someone who had to sleep in the same room with the dog. (dogs don’t digest plant material very well)

      • A parents curse “may you have a kid just like you”
        the grandparent blessing giving the little copy back to it’s parents

    • Didnot realise you had already posted this comment as I have been watching the cam .

      • *hug* This is no competition. We only want to provide useful information. And if that appeares more often. heck why not.

        • Great minds think alike (well in your case but in my case a think an acorn nut is quite appropriate) x

    • been doing that for a while now watched it earlier today, what are thelights further down the slope

      • If they don’t change their form, could be cars of volcanologists of journalists …

    • Is this now a plume we are seeing and does it mean that magma is now breaking through to the top .

      • Yes, it is a (very small) plume – and has been a such. If ash comes out of a volcano, this always means that the magma is breaking though – in this case at the summit crater.

        And ash clouds are consisting of hot ashes, water vapour and a lot of different gases. :)

  5. And here is the count of the points.
    DFMorvan 2 points for Auckland Shag and the Ross volcano.
    Scheteve42, 1 point for the Alkali Basalt.

    Note, I will never award a point for just Basalt, it needs be more specific.

    • Yeah i know, but i think i would have some ideas how to create an un-google-able Lava image.
      Congrats to the winners, though maybe David should get one extra point too because he pointed out it can be googled and gave the first letter proving that he had it right. He just thought it was cheating and so, refrained from giving the result.

      • I has exactly the same reaction last week and also pointed to the image googling. Of course it helps because frankly who could guess just by viewing the image ? Maybe the questions should be more specific or not just about the volcano….

          • Congrats dfmorvan. Well maybe a honorary mention for you last week and for David this week.;) I was impressed about the result of your picture which was never online. And the time it took to resolve it. Dont want to scroll back but i think that were 0,27 seconds.

          • HI Spica
            Yes the speed and accuracy of the search engine is baffling. Of course this place is pretty well known and there are probably 100 +pictures in systems like Flickr and Panoramio but still it is impressive.

        • Hi Alan

          No, Actually i’m pretty happy to have found some of the answers :grin:
          the only thing which worries me is that the contest will only become a speed competition. I only beat KarenZ by a few minutes, so in the end the contest becomes a test at using google and the other search engines and one’s skills at digging info (because not all was in the google search happily). So I think we need ot find something different to keep the contest its interest and fairplay.

          • Evening DFM – I think Carl agrees as well!
            I have one or two ideas…….. really evil…..
            Would you have any lava pictures of your own that no-one has as yet seen, therefore Giggle-proof? If so, please send to Carl via VC mail!!
            Glad you agree! :-)

          • @Alan What about scans from photos in volcanobooks older than 10 years maybe flipped over and checked in google beforehand? I like it when we got to search and compare, but i agree it should not become a speed competition.
            And i am against being more or less forced to download that google app.

          • Spica
            What a good Dragon coming up with another idea, but please check with your Master regarding Copyright issues (always my pet ‘thing’ after an ‘event’!) if we use published article photo’s.
            In a way, giggling takes away the educational aspect, the more we hunt the more we learn!
            There were 43 sheep at Lady Heck’s farm today – we have a nice home-made Mint Chutney……..!

          • Yippee Doesn’t Lady H look gorgeous!!
            Sheepies!! Thats what I saw earlier, easier to count as not moving about!
            Our Swallows and House Martins arrived this evening, so perhaps they’ll bring summer!!

          • I enjoy doing Google searches & I’m just happy that I found the answer. :D

          • @ Karen
            I think the idea is to make the Sheepy quiz more ‘hunt-the-answer’ rather than ‘look-it-up’, but we’ll see; the Goolge searches may be more fun than before (?) :-)

          • @Alan You’ve lost me completely. What’s the difference between “looking it up” and “hunting” it? Googling the image did not provide the full answer …..

      • I would say if this was continous it would be a VEI-2 after 2 weeks, and a VEI-3 after 20 weeks, and a VEI-4 after a whopping 200 weeks.
        What I am after, this is 100 times smaller than Eyjafjallajökull, the ash is of a heavier type than Eyjafjallajökulls ash (so it drops down quicker).
        In short, vacation time for Judith :)

  6. Sorry if someone has already posted this. Eden channel. Wednesday 8 o’clock. Life On Fire . New programme about Iceland volcanos. Sounds like it could be interesting.

  7. How much time does is normally take to check on an earthquake (depth, magn. a.s.o.)? IMO people seem to be working intensive weekend shifts today, next to all the quakes of today – and the rest of the weekend are 99% quality.

    • That varies a lot depending on how difficult the actual quake is.
      But in this case it also is down to if there is activity warranting them to be on duty during the weekend.

      • And I think that it is Askja that is warranting it. There has been prolonged and persistant activity combined with GPS-uplift.
        But I am not sure.

        • Could it not also be Hekla (strainmeter was falling today very abruptly, now going up after, and Búrfell falling a bit – but not much though) or Hamarinn (quake today again)?

          BTW: It seems at Hamarinn were a lot of small earthquakes also in 2010 – before the jökulhlaup http://www.vedur.is/media/vedurstofan/utgafa/skyrslur/2011/2011_011.pdf (esp. p.12). Landsvirkjun let do a research on them to know if there were some under the reservoir Hágöngulón – they used the SIL Skrokkalda and 4 transferable SIL stations -. The result was, that there were no quakes under the reservoir, but a lot of them around Hamarinn. The plots are interesting and almost – but not really of course – as good as Lurkings.

    • I think you may be interested in the same patch I noted some weeks ago. I have been watching it since and it seems to be a depression, partially filled to the left by a mound with a steep-walled canyon leading out of it. Since it lies on the lines of fissures, it being snow-free could be an indication of a slightly warmer micro-climate. In other words, it’s one of the places I’d be wary of entering without a gas mask and an independent supply of air.

      • Er, Its free for all to watch, but I think there are no travellers anyway upon Hekla now these days (?) Lo areas (shallows) are basically filled with snow, those patches have steep sides, like cliffs, or are rough lava field tips, having less snow on them due winds blowing, and that little that remained has melted.
        I say, its a fail watching for signs of “new” hot-spots on Hekla, as its spring (so many more patches are appearing) – All normal, but still much snow on higher slopes.

        • See that patch? Well, go a little bit right above where there is a small ridge, that’s the spot of the 2000 eruption and this patch (now covered with snow) was very hot ground at least until last summer (and was usually snowless). I think the snowless patch you see now is just a warmer microclimate spot. Because it lies in southern slope, protected from north winds and with sunlight during the afternoon: melts faster.

  8. There is microseismic swarm together with harmonic tremor going at Theistareykjarbunga right now.
    Calling it a quake swarm is a bit too much since we are talking about 4 quakes ranging from 0,2 down to -0,7M.
    But microseisms with added harmonic tremoring is interesting in it own way.

      • I still think this is caused by lady H, the daughter of Mrs B.

        If L. would be the cause, then Fag would show something in tremor.

        • Cast your eye at the SILs surrounding Myrdalsjökull then the lack of corroborating tremor at Fagurholmsmyri and ask yourself “If it’s not Niburu L, what could it be?” Niburu E? Niburu V? Or could it be that E, V, S & L are not separate entities but different expressions of Niburu (“There can only be One…”)?

          By now, I’m beginning to question if we have not allowed ourselves to “have been spuuked by a vedeo-geem” and if someone could show an undeniable link between human activities at that power-plant with all the spikes seen, I would embrace that option.

          • I’m thinking its the dam, now.
            But still I keep an open eye to the volcanoes around.

          • It is not the dam.
            It was situated in the northern third part of the second Laki-fissure.
            I have also sniffed around and found that the dam is totally out of the question.

      • I think, vatnsfell is influenced by Landsvirkjun letting flow a lot of water down the river in direction of Thjórsá. There is this power station nearby.

        And the tremor at Skrokkalda could come from Hamarinn.

        • I also checked on the water, there was a sudden increase in Thjórsá. http://vmkerfi.vedur.is/vatn/VV_Frame.php?r=22071&load_graph=1&direct=1&station_id=218&station_name=Su%F0urland&page_id=268
          If you can’t get in here, go to Icelandic IMO Forsida – click on blue Vatnafar and just on one of the stations near the river you’d like to inspect. So scroll down left. If you look at “Suðurland: Þjórsá við Þjórsártún” and set in “4 days”, you can see a considerable difference in water height (60 cm) in a very short time span.

        • Henry I also think E, V and L could be expressions of something single. Maybe the hotspot is feeding a main branch right under there. Its difficult to triangulate the right spot when only two stations seem to show this, Vatnsfell and Skrokkalda.

          I still consider that it could be the power dam (or even hydrothermal activity in the glacier), and if water in Thjorsá has increased, well this can be either dam activity (at this time of year, much water is melting down the river), or any source of small flood from one of two glaciers, Hofsjokull or Vatnajokull (this way it would be lady H or G). I doubt thism because we do not see any tremor there, maybe lady H, and even Hofsjokull (but also no earthquakes or tremor close to it).

          I now think it could be well the dam that is causing this.

          • I think you can possibly see it at Snaebyli even if it’s heavily masked?

          • I think, I know what you mean now, Henri. But I am only able to see a connection between Vat and Skrok, because of the fissure system in this region (SW-NE). On the other hand, I could perhaps see another strange connection between Grf and Snae. Seems really strange … hm …

          • The facts here are until now:
            - tremor events in Sko and Vat, but only high frequency, so if something is only hydrothermal, or water related
            - triangulation suggest source somewhere in dead zone, between the dam and H., and between L. and V.
            - this time is a melting season in Iceland, this can be the likely cause of it. Extra water.
            - H. has been restless since last year, also some earthquakes at times in H. but so far it does not suggest anything significant yet (H. is usually noisy and we would see something more dramatic at both stations
            - L, E or V is a possibility, it could be some deep intrusion happening, but if it is, it would be something minor, cause no earthquakes observed in there

            I wouldn’t worry with this much more…

      • I am not sure Suzie but I think IMO had altered the scale on the graphs. A higher scale would make it look like a sudden drop. if the Hekla plot is rising very fast and threatens to go “off the Plot” the IMO change the scale to accommodate this. However I could be 100% wrong on this.

        • @ Suzie and Diana, Last week IMO halved the scale to the left to accommodate the high rise at Hekla so I think it was definitely a drop – but, that said, it could be a fault in the machine. I think it was real, but as Islander said yesterday (on the previous page) Burfell has to fall at the same time or just after for it to mean something dreadful.

  9. Is there wind at hekla–just watching web cam and there was movement for about 10 sec? About 7 mins ago.

      • Thanks Talla – went back to watch after post and again movement-so now i know cam does sway. Just love that view! And was watching the movement in lower left-assume those are the sheep Alan referred to. Or could it be an observation point?

        • That’s where the sheep are – I think it’s part of the farm but Islander can tell us for sure. :-)

          • The sheep, appearing nearly every day on that small field, belong to Farm Helluvað (out of picture on left side). Yes, cam is up an GSM antenna pole run by Mila (and shakes in the wind quite often).

  10. Mýrdalsjökull / Katla / Godabunga didn’t show much activity lately, but I think the very fast changing waterlevels in the river Hólmsá/Skaftártunga station are a bit strange. What do you think about it? http://vmkerfi.vedur.is/vatn/VV_Frame.php?r=28787&load_graph=1&direct=1&station_id=219&station_name=Vesturland&page_id=307 This has been going on for some time now – you can see it, if you set in Scale: 2 weeks, and up to 40 cm in 2 hours or so. This is a river which comes down from Mýrdalsjökull.

    Would be interesting to see the conductivity data. But can’t get in there. Does anybody else?

    • This is melting time of the year. Rivers from glaciers can increase by several times. It could be just there. But if conductivity is increased, then its a different story.

      By the way, I just saw some steaming coming today from Eyjafjallajokull.

        • That means hydrothermal activity has increased. Because extra melting should have diluted salts and chemicals and decreased conductivity. So, yes, increased hydrothermal input under K, which is totally expected as we approach summer now. Wautch for a new likely summer season in K.

        • Inge, Irpsit. Having had a look at the relevant vöktun-side map http://hraun.vedur.is/ja/Katla/Myrdalsjokull_170112.jpg and checking the relevant SIL stations, there’s a lot to support such conclusions. Austmannsbunga (just north of the Katla caldera) has been showing the Godabunga/Grimsfjall type of activity for months, indicative of high levels of hydrothermal activity. Smjörgil, on the slopes of Eyjafjallajökull but not as close to that crater as AUST is to Katla’s, also shows this type of activity while the SIL-stations on the run-off areas of the two volcanoes – Slysaalda (Katla 12 o’clock), Snaebylie (K 2), Rjupnafell (K 3), Lágu-Hvolar (K 5, on the Múlakvísl river), Álftagróf (K 6.30), Eystri-Skógar (K 8, E 5) and Midmörk (E 10) – all show what could be interpreted as a combination of the hydrothermal events and effects of the increased run-off of spring melting.

          Since someone said that the money earmarked for improved monitoring of Snaefellsnes was appropriated and invested around Katla after the Eyjafjallajökull eruption in 2010 as well as new British funding being made available, it’s easy to surmise that the increased activity spotted is at least in part due to increased and improved monitoring equipment. With all this in mind, could we tentatively interpret what we’re seeing here as the combined effects of a continued post-eruption cooling-down of Eyjafjallajökull with normal hydrothermal activity of Katla made visible by better monitoring in conjunction with the usual spring melt having started earlier this year?

          Even so, there is increased activity from Nibiru west of Vatnajökull to Theistareykjabunga that cannot be explained in terms of normal, seasonal variations. As an example, while the activity of the last few days at Vatnsfell could be explained by Landsvirkjun opening the gates in response to the spring floods, I very much doubt it explains the events at Skrokkalda around April 19th-23rd, nor can it be applied to the activity around Askja. Even if there is a large geothermal plant at Reynihlid, the activities recorded by that SIL station and the nearby Krokottuvotn exceed the normally induced pattern of the power plant.

          (Note, amateur interpretations of a subject barely if at all understood.)

    • Suzie look down the left (y) axis…….The strain count per second -1…The range is 0 – 50 and 0 – -50 at the present..
      This scale often gets changed. Back the day before yesterday, just before the big drop the range was 0 – 200. At 0 – 50 the peaks and troughs are very pronounced.
      Please someone tell me if I am not correct with this. This is my interpretation and sort of self taught here.

      • Hi! (Also self-taught!) Yes, at the moment the scale is 0-50 which actually makes the peaks and troughs look bigger. They were actually bigger when the scale is 0-200. A couple of weeks ago when HEK and BUR were really angry they kept it at 0-200 for ages. When it goes off the scale at this range, I believe we will be having a ‘situation’! :-) Experts please jump in here if I’m wrong.

        • Those values are hard to compare since they have changed the values 3 times since then.
          300 back then would be something completely different now. As far as I understand it would be near 300 000 in todays values.

    • Hello Suzie:
      The nomal value is 500, often the scale is 1000 and I have seen 10 000.
      Estimated eruption value would be 300 000…
      50 is a very soundly sleeping volcano.

      • Thanks Carl
        Know what? You and your team are splendid – even the true amateur like me can make inane observations and ask ‘obvious’ questions without feeling embarassed! And that is a real benefit as I try to grasp the fundementals of a pretty darned complicated science! XX

  11. One local report from me: this afternoon I saw some small steaming coming from Eyjafjallajokull. This is nice to see but nothing really significant, it has been several months since last time I saw some steaming from its summit but sometimes it still happens, the crater lake there is still hot and steaming is expected if the weather is cold (as it is now) and the wind calm. Today I have a very good view to Eyjafjallajokull, the weather is excellent.

    On another hand, it has been long since I last saw steaming from the drillhole site at Hengill. I guess they haven’t been drilling there lately. Also, no significant swarms there either.

    How funny to follow volcanic activity just by watching the volcanoes every day.

    • I am no expert but i have been watching this cam for more than a year, and i would say this is what it looks like when clouds ( normal clouds) move over the mountain. If you compare the pictures of the last days, there was fresh snow on the mountain today which was not there yesterday. I think there is not even a strong plume atm. So i d say, bad weather, nothing else.

  12. If they discharge the lake dam near Vatnsfell, that would explain the now quite regular tremor recording. I am getting more convinced of it.

    • I have checked, there was no flows when the two first spikes occured.

      • Thanks Karen, im just in hope of spotting something first. Lots of interesting stuff going on around the world at moment, although iceland relatively quiet. Few pages on my site with volcano cams to try making viewing, monitoring easy. If anything I can add or change to make better please tell me.

  13. Eruption on Sakurajima this evening:

    Not recorded; but, for ornithologists the birds got very agitated just before the start of the explosion.

  14. No.. I haven’t fergotten ‘yall. Just having a fight with data and sitting in awe at the various tephra geochemistry leads.

    As for Popocatépetl, ya know what the really fascinating part about it is?

    Where it’s at.

    Popocatépetl, along with it’s sister volcanoes up through that area of Mexico, are driven by subduction melting. The same process that drive Mt St Helens, Ranier, Hood, Merapi, Fuji etc.

    But notice how far back that line is from the subduction boundary.

    Popocatépetl and brethren, are being fed by flat slab subduction. The subducted plate rides almost parallel to the overriding plate. That means that the melt producing region doesn’t reach teh “sweet spot” until about where Popocatépetl is at.

    Just an FYI from the peanut gallery.

  15. Good morning/evening everyone. A beautiful sunny day here in the UK AND it is a public holiday….This is most unusual :D
    I have quickly done the rounds and have little to add to the daily situation.
    There is a hint of harmonic tremor around Hekla I think. Very small but I am watching

    http://hraun.vedur.is/ja/hekla/oroi_mjo.html

    Although the strain doesn’t look too interesting.

    • Morning Diana! Raining and cold here in the south. :-(
      I noticed that spike in Iceland as well – it seems to show up on lots of the SILS and I thought there might have been a big quake somewhere in the world – but nothing shows up. I’ve no idea what it can be, but it looks interesting :-)

    • This is a region where minor earthquakes are normal but the last earthquake over 5.0 was a 5. 9 in 2000.

      • There has just been another quake over 4.0 the interesting thing is that each quake has become shallower from 10 km to 8km the most recent is showing is at 2km.
        Does this have any significance to anything.?

  16. Hello Dean
    I am fine thank you just concentrating on my holiday we go on holiday next week and I am just waiting for my appointment of my test under GA which now will be when I come back from holiday .
    Your Father is in a good place and will be well looked after.

    • Its good you are going on holiday Judith well done and i think that everything is coming good! Take good care of yourselve and your husband and i wish you a very good holiday together! Friendly greetings Deanne

  17. May I draw your attention to Vestmannaeyar – http://hraun.vedur.is/ja/oroi/ves.gif At a first glance there seems to be quite a lot going on there, especially if if you look at the blue lines representing tremor in the 2 – 4 Hz part of the spectrum?

    Now take a look again. On the 30th of April through May 4th tremor rises to approximately 2000 whereas on the 28th & 29th it only reaches ~1500 and barely 1000 on the 5th & 6th. Today, there’s again a sharp rise to levels reaching 2000 or above. So, what causes peaks in activity Mondays to Fridays?

    This is a perfect example of human activities registering on the tremor charts. You can even see that tremor is less to some extent on May 1st and I’m pretty confident that if you know the routines of the fishing industry, you can see this reflected in the tremor chart too.

      • Here’s another one with human activity (I think) – I assume 1 May is a holiday in Iceland (probably?), you can even see that the activity on that day was different than the rest of the week (similar to Sundays):

    • If you compare VES to Sandskeid that lies next to the main road out of Reykjavik, you can safely deduce that the inhabitants of Reykjavik are far more conscientious in their observance of May 1st than the heathen fishermen of Vestmannaeyjri. ;)

    • I like this one…..

      I think it is near an airport. This morning was very busy with people flying back after a long weekend!
      Others fascinating repeat patterns are those SILs near the coastline when the sea waves and tidal activity registers in strong winds. It shows how much pressure breaking waves produce.

      • I must add that despite the sunny start this morning the holiday Monday here has followed the normal UK pattern and it is now bitterly cold and raining. I think my bean seeds are creeping back into their skins as so far only 3 have emerged….and this the second sowing in the greenhouse.The first batch rotted due to cold and frost. I cannot remember such a cold Spring.

        • Hi Diana, even down here in the supposedly warm south I am having to germinate seeds on my windowsill indoors before moving them to the greenhouse once they have sprouted. They then sit there not moving as a protest at me daring to move them from my cosy house to a damp gloomy greenhouse! Ist April I planted out my geranium cutting that were growing nicely in the greenhouse and would usually take of in the usual April showers. this year they haven’t grown since planting out and are starting to rot in the garden. :( What a horrible Spring. We had it so warm in march we had a BBQ now back to winter.

      • Vogar is indeed not too far from the international airport at Keflavík! :)

    • Unbelievale, you guys made my day. THis observation is pure genious and shows how sensitive SILS are. So, I guess magma moving under a volcano stirs a lot, not just a bit.

      • Alas, it’s only in the (blue) 2 – 4 Hz range that man-made interference is that easily visible. But now that we know what human noise looks like, we can again turn our attention to three SILs that show a lot of activity:

        Askjahttp://hraun.vedur.is/ja/oroi/ask.gif
        There is no evidence here of human activity (and none to be expected). Peaks occur as they please; in the middle of the night or during the day, on weekdays or over the weekend with the greatest activity shown in the early hours of May 1st, a public holiday. This is unquestionably Mother Nature’s doing.

        Vatnsfellhttp://hraun.vedur.is/ja/oroi/vat.gif
        The past five days during which there has been a lot of activity includes a weekend. Most tellingly, the peaks occur irregularly and haphazardly over the whole 24 hours. Why tellingly? The weather has been good with little or no precipitation, thus if it was due to water being let out of a dam in order to stop overflowing, it ought to have been
        a) at regular intervals, and b) there would have been a periodicity present and visible due to the fact that melting is always at its greatest in the early hours of the afternoon. As nothing of the kind is visible, there has to be other factors at work and since we have ruled out human interference and spring melt…

        Skrokkaldahttp://hraun.vedur.is/ja/oroi/skr.gif
        There is a symmetry between the 2 – 4 Hz (blue) tremor shown at Vatnsfell and Skrokkalda which means the same conclusions apply. Furthermore, the timing of some of the events coincide which means that in those cases, there’s a strong likelihood of it being the same event. In other cases, the activity shows up on just one of the stations, or if at both at greatly different intensity. This means that the activity shown by these two stations is not at a single point but at several, something which tends to reinforce the impression that this has nothing to do with Landsvirkjun or spring melting.

        Just being an amateur and thus having an imprefect understanding, fumbling about in the dark, I’d really like to hear what a professional has to say.

        • And comparing vat today to last years “pattern” then there vill be eruption.. tomorrow. But if that fails, this only shows that Nibiru mainframe system is broken or out of order (simple theory never work, so no worry). *not-expert-TM*

          • Not necessarily (an eruption tomorrow). What applies to one volcanic system is not true for all and conditions can change so rapidly, especially after a previous eruption, that what was true then might not apply now. I think that all we can say is that there is something going on, but where and what?

        • Henri, your reasoning makes lot of sense. Yes, I think this is probably not human activity, and I doubt it is mulfunction, because Sko shows the same but to a lesser degree. But it does not show over NE of Myrdalsjokull, therefore I think this is not related to Laki. I think the source is somewhere between Torfajokull and Hamarinn (it also does not show at Grimsvotn SIL). But whatever it is, it is pretty small and almost lost within the noise. It also never shows in high frequency. So, I think this is not that important.

          • Islander, Irpsit, my fellow sleuths! If you compare the Vatnsfell tremor from last year ending in the Grímsfjall eruption (thank you!) with present-day tremor, there are differences and similarities that I interpret as yes, there is something volcano- or (more accurately) magma-related going on. No, I doubt the source is Grímsfjall this time and no, I can’t see it in any of the Mýrdalsjökull SILs. The peaks at the closest of these, Snaebyli (SNB) and Slysaalda (SLY), do not really align with the rest. Nor can I see any connection with Hekla (HAU and GYG), the latter inconveniently offline since last Thursday).

            Unfortunately, there’s a big gap in SIL-coverage between Skrokkalda and Askja – Mokollar -Kreppuhraun, but as nothing of this activity shows up on the latter or the network of stations east, Askja can be ruled out as the source, especially so since the peaks at Askja does not match those at SKR and VAT.

            Going north to Hveravellir (HVE) located between Hofsjökull and Langsjökull, there is activity going on in both 1 – 2 Hz (green) and blue 2 – 4 Hz. Again, no match. Going south, or more properly south-east, to Kálfafell (KAL) and Fagurhólmsmýri (FAG), same story, no match.

            So where does this leave us? As I said earlier, the differences in intensity – a peak showing strongly at VAT but not so at SKR, another shows strongly at SKR but weakly at VAT whilst some show about equally at both – argue not a single, but several sources. The lack of corroboration North, South, East or West argue a location “East of Katla, West of Vatnajökull (Grímsfjall, Bardarbunga, Hammarin), South of Hofsjökull and North(-west) of Örefajökull”, that is in the Dead Zone. For all I know, this could be perfectly normal but there is that similarity of VAT between today and last year that ended in the Grímsfjall eruption.

          • I give you a clue :)

            Veidivotn system runs from just at the edge of Torfajokull caldera to Hamarinn. So, it crosses through Vatnsfell and passes closely to Skrokkalda. Its actually nearby the two SILs, if you know the area. In 1477 the whole area erupted at multiple places, at least including Torfajokull and multiple places along Veidivotn. I think this is the source.

            Hofsjokull, the nearest volcanic system also seems pretty quiet. And Veidivotn just links to Hamarinn (the entire whole area erupted in Thjorsáhraun eruption), and as we know Hamarinn has been restless lately.

            I hypothesize that magma is coming from deep at both Hamarinn and Hamarinn and injecting towards the dead zone alogn Veidivotn. But this is quite soft still, maybe everything is occuring at great depth still.

          • I meant to say “magma is coming from deep at both Hamarinn and Torfajokull and injecting towards the dead zone along the Veidivotn region”

          • If so, why is it that we see it clearly at both Vatnsfell 30 km from Torfajökull and at Skrokkalda 80 km away, but see absolutely nothing at Slysaalda SIL, a mere 10 km from Torfajökull?

          • Dear Irpsit, could you differentiate between Bárdarbunga and Hamarinn?
            I know that they are most likely linked, but the Veidivötn Lava is having the Bárdarbunga signature of REMs.
            Just a point, you sometimes mix them up a bit. Hamarinn is not the main volcano, it is the bitch boy of Bardarbunga after all :mrgreen:

  18. Today there is an article at a Danish science site:

    http://videnskab.dk/miljo-naturvidenskab/varmen-fra-helvede-skal-hentes-op

    A translation of the headline would be ‘bringing the heat up from hell’. The article is featuring a story about how the icelanders drilled for geothermal heat in the vicinity of the Viti crater at Krafla, and what is currently being done.
    As the article is in danish it is probably restricted to a small audience, but i’ll post it anyway

  19. Fer Carl….

    Have started the Nibiru part of that project. Enlil and Enki related data is in your VC mail.

        • Any change you all can stop calling volcanoes nibiru – I missed that bit of the thread an it’s been going on for a few days now and I’m just a bit lost as a result – it probably doesn’t help a number of other visitors. I know this is still the Dalek Baa page, so I’m probably out of order asking for sense to be restored ;)

          • All will be revealed soon I guess.
            There must be Super- Blogs waiting to happen ! Well! You can have Super eruptions, Super- Tsunamis..Everything these days has to be bigger and better to feed the public’s insatiable appetite for something bigger than yesterday’s Celeb happenings. I see no reason why we cannot have Super Blogs too. :D We have access to watching some of Mother Nature’s super Celebs here.

          • No, not untill Hell frezzes over >biggrin>. Thats what someone said. Nibiru is not A volcano per se. As this is non\existing volcano, its quite fiiting.
            The L Nibiru, S Nibiru or V Nibiro are events that have calculated reoccuring periods of about 241 years. So it might not come within our lifespans but our master plotter calulates we are about 229 y into the next one. Might I say its question of age, if it is relevent or not to us. I does not save France change president.
            |now the keybord is acting up|

          • ooops, that backfired. my last comment was not at Spica, rather next E L one step before

          • correction to a correction … of course D B is NOT a Dragon Lady. Sorry Spica, sorry Diana |time for coffee|

          • Geolurking, I hope you have considered not only the big eruptions but also the minor ones near the dead zone. After 1783 L. there was an eruption in 1862 to the NE of Bardarbunga and in 1902 (unconfirmed) and 1910 (confirmed) to the southwest near Hamarinn. It seems that in small eruptions, the magma does not intrude as far as in the large eruptions. The small eruptions are poorly understood as they went unnoticed because the place is so remote and since they always occur in same spot, magma covers the spot of previous eruptions (it also poorly studied the dead zone lava fields)

          • Yes, let us please stop it…
            I know I started it due to me feeling reticent of starting a Laki scare. But let us call it Laki, Veidivötn and Eldja instead. Just to make life easier for everyone.

          • Irpsit, why include the small ones?
            Especially those that are not in the dead zone?
            Because those happen almost all the time in Iceland, then you get to much noise when trying to find out what differentiate the large ones.
            When we know that we could check for a couple of small ones that happen outside like the 1910 eruption from Bardarbunga.

          • Well, we can always say all the volcanoes of Iceland per this system: small letter for small volcanoes, big for big ones, have fun with this:

            southwest belt: r, k, b, H, P, L, HO, KE, g
            west belt: S, l1, l2
            eastern belt: g, H, v, W, TI, E, T, K, G, t, B, h, O, e, KV, TU, S2, A, KR, TH

            Can everybody figure them out?

            Only “central” volcanoes posted, but of course everyone will have a different opinnion on what to count as an independent volcano in Iceland.

            Carl: I will now onwards call only by their proper names

        • Edward, Nibiru is the name give to a fictional Brown Dwarf companion to our sun (alternatively an Earth-impacting huuuge comet) invoked by the 2012 crowd. The way these delusional creatures go about interpreting every minor or major geologic hiccup, be it earthquake or volcanic eruption, as directly attributable to Nibiru’s forthcoming “World-Ending As Proven By the Mayan Calendar” encounter with Earth on December 21st has led us to jokingly refer to the “world-ending” fissure eruption they would proclaim on the basis of a few earthquakes and minor tremor observed in the Dead Zone as “Nibiru”. Should anything, God forbid, happen in the Dead Zone, I hope the Icelanders with their great sense of humour and ditto common sense will refer to it as “Nibiru”, just to rub it in.

          PS. Eldgjá in 934, Veidivatn in 1477 and Laki/Skaftár Fires in 1783 all occurred in the Dead Zone.

          • Vatnaöldur was a big one. But the largest of all was Thjorsáhraun, which is largest eruption on Earth per amount of lava release, in the Holocene.

  20. Now to get back to the hum drum!
    Mrs Hekla has had a funny turn this morning. A sudden, sharp increase in strain which dropped and she is now still steadily increasing. I have never noticed this upward leap before… down yes,

    http://hraun.vedur.is/ja/strain/1sec/index.html.

    The scale has not changed so I think it is mrs H’s internals rather than interference from IMO.
    Nothing much to see on the tremor graphs except Mjoaskard is still showing some tremoring.
    It’s had these days to interpret these graphs as so many are showing quite dynamic tremor compared with last year. I just wonder if the equipment is now more sensitive .
    I do get the impression that the rifting is certainly more pronounced this year. Maybe this increase in the activity of the MAR in this area is causing a more noticeable recording of tectonic activity

      • I am pretty sure it’s just weather clouds Forestred. I will only get excited when Hekla has a couple of proper quakes right under or very near. This is her usual Modus operandi. A couple of sizeable quakes and then eruption within the hour. The strain graph will be unmistakeable.
        Of course she may have other tricks up her sleeve, but I expect a very definite, unmissable large black eruptive cloud and no pretty little white fluffy, steamy stuff.
        Sorry to disappoint you. :)
        OH! And she will only begin to erupt when I am unable get to my PC!!! :D

    • OOps… Please read “It’s hard these days to interpret these graphs……”
      I am not having a good day so far! It’s a pity I can’t start today again in a more organised frame of mind. Ah Well! Some coffee and a short break is called for… BBL. :D

        • Hi GeoLoco! I agree with Henri – Earlier today it looked as though someone was trying to fix SAU – the three colour lines were all lined up on the grid lines – but then it went haywire again so I think they are having problems with it.
          Hi Diana! I saw that funny upward jump this morning – I think it’s ‘real’ as opposed to machine related. Lady Hekla twitching in her sleep? :-)

          • Hi scottisch Lavamate of the year,
            So for sure I’ll not miss Hekla’s show tonight…

          • LOL! I watch Hekla a lot – but she’s sure to do something dramatic when I’m away – so look out for the week beginning 4th June – I’ll be in France then and totally internet free! :-)

        • Thanks again.
          But, well, am I really back? We’ll see. “Tuff stuff” these days (phew – weeks…).
          I miss getting lost in here. And it’s important to make sure you don’t turn to serious. Godabunga!
          Looking forward to hang around more again.
          BBFN

  21. I am sorry that I have not posted a new one for a couple of days. Real life jumped up and bit me quite severely in the behind part of my anatomy.
    I am chugging along on the next instalment of the Naples quadrology (probably going into a quintology), and I am also writing a piece together with The Master of Plots.
    I will put in a new one later today, but from another of our posters.

    Regards
    Carl

    • Can be a bit knotty that real life thingy. I am kind of in the same position. With any luck I should have a bit more time from Friday.. (the voice of misplaced optimism).

    • Respect for all the work on the café.
      Incredible amount of knowledge shared and generated.
      You’re one of those standing up against the powers of real life. Ehm, I’ve got a terrible image roaming around in my sick mind right now – I see you as a scottish fighter, Braveheart-like, naked under your kilt, running throug the plain to fight the ones that try to bite you where we know… Terrific.

    • Ah well, life happens and bites. I’m in the middle of a biting episode too, if that’s of any consolation… Hope your bites go away soon!
