2nd. fissure eruption started.

Today in the morning hours the fissure which had produced lava flows 2 days ago erupted again. One could get quite a good glimpse on the ongoing eruption on the Milacams.

The eruption occurs at the same place as last time ( Holuhraun). The fissure seems to be 1,5 to 1,8 km long. It appears in a place called Holuhraun ( Quote Carl: “Soon to be Holudyngja, and after that we have Holubunga.” ) but the lava comes from Bardarbunga through a fewer tube. The new shield volcano which might be forming does not yet have a magma chamber of its own.

“This is a much more powerful eruption than the last. It is much, much more lava coming in this eruption, but the volcano, “says Sveinbjörn Steinþórsson technician from the Institute of Earth Sciences, University of Iceland, but he looked eruption of lava pocket this morning, along with other scientists.

“Strokes are 20-30 meters high. There are no explosions in the eruption. The eruption occurred at the exact same place as the other day, except that the crack reaches 700-800 meters further to the north. The crevice is out on the sand, ie out of the hole lava.

This is much more healthy than the eruption of the day. The activity is stable at about 1,200 meters long fissure. There is a crater south part of the rift is odd, then erupts in all the cracks. ”

Sveinbjörn Steinþórsson technician from the Institute of Earth Sciences, University of Iceland also saw the eruption that began August 29. That eruption lasted only about four hours. “It really fizzy died immediately. It reduced the time we were running from the hole lava, but started up again in a few moments. This eruption has been more active since we got on at. 6 in the morning and it does not seem to be falling down. The eruption now changed little while we were watching it. It Jost bit while we were running out and has been a constant for about two hours. It’s been quite a lot of lava here on the east side of the crack, but we can not see what it is yet much lava west side. ”

The scientists returned from the eruption site on kl. 8 in the morning. The weather was beginning to deteriorate. Considerably high sand storm is in the area and dry. Forecasted deteriorating weather east later in the day”

Last night many readers got enthusiastic because lights were visible on the webcams provided by Mila. The scientists driving around had a good laugh. They fooled us. What was visible were only cars.

I am using 1 image ( screenshot)  which i did myself but since i have troubles accessing the cams, most images come from readers who uploaded their screenshots to tiny pic, i downloaded them and uploaded to VC. Please excuse if i did not mention your name. I am in from my holiday hotel with a very bad wlan connection and i am just writing a post instead of having fun on the beach. So the last post does not have over 1000 comments attached and starts being really slow. Nevertheless i suggest you go back and read the last post. You will need it to understand what is going on.

It would be wise to check out the youtube live stream instead of the cams. Youtube can handle huge loads, the Milacams can handle a lot but not what’s going on right now.

There is a storm over Iceland now. The remnants of Hurricane Cristobal, so fog and clouds will cover the eruption, most likely, but is still ongoing as this post goes in. And supposedly much stronger than the last event.

Update: Carl:

A WARNING: I know a few wish to go there right now.
But, remember to stay on the where the wind is not blowing, this is a very gassy eruption high in SO2. Even one breath of the exhaust would kill you.

  1. Hi Guys,

    Do you have an idea on what causes the earthquakes under Herðubreið ?

    Is it a prolongation of the dyke or is it unrelated?

    • The MAR passes between Askja and Herdubreid and as it is diverging, there’s a lot of stress on the rock and it fractures quite often. Up until this crisis, 99.9% of the not inconsiderable number of quakes (~10,000 or so) have definitely been tectonic. This intrusion places even more stress so it’s not really surprising that the faults readjust all the time.

      • If you can load the new 3DBulge visualization and spin it to look along the wall of quakes in the current erupting fissure, looking northward to the swarm under Herdubreid you can also seen a faint wall of quakes that connects them very well

        I would post a picture but it really does not show very well, it shows up much better as you tilt and swing the picture around

  2. While taking a depressing stroll around YouTube I see that someone has managed to identify a UFO on Bard 2 while it was a bit out of focus a day ago. And as for the tinfoil brigade, they’re going nuts right now.
    Oh, and the outskirts of the storm are lashing Skye just now. The Cuillins have disappeared 😦
    Just passing time 😉

    • I am pleasently surprised that no tinfoilers have come in through the door (might be that a Dragon made short order of them if they did).

      Our new reades prove the point that there is intelligent life out there, I think all of it is now in here :mrgreen:

      • I’ve saved you a leg! He said he’d come a long way and that his legs were tender so I took him at his word. If you hear any sated burps, it’s one of the Lady Dragons who got dibs on the best parts, the innards. :slaverdrool:

    • @EyeofSkye: My friend on Waternish posted a lovely picture this morning of her view – but said it was about to disappear as the wind was up. I guess you are on the west coast of Skye, near Carbost or Bracadale?

  3. only one comment on tinfoil hats……….. they really improve the television reception in remote places. DH and i used large ones. i used to wonder what anyone would think looking in the window. Best! motsfo

  4. I have no idea if this is of help to anyone without live streams. RUV the Icelandic radio and television company has the Mila can up and running as well and I am watching it both on my computer and my TV. Here is the link : http://www.ruv.is/beint

      • There was a revised estimate of lava quantity in this evening news in RUV

        ohr August 31, 2014 at 19:08
        Estimate of size of todays eruption is 250 m3 af magma pr second according to Magnús Tumi Guðmundsson proffesor in geology @ RUV just now.

      • Please that must be a typo, that is so incorrect.Even someone with no knowledge of volcanoes can work out that you cannot get 1000 tons of gas from a 1000 tons of solid,the magma is 50% silica so 500kg per ton and the rest is not SO2 there are other minerals plus CO2 and H2O.Daily output of SO2 from an event like this is probably 10000 tons max.

        • 1 cubic metre of lava is around 3 ton, so 1,000 cubic metre is about 3,000 tons. 1,000 tons of SO2 would be a bit high, but not an order of magnitude. It should be noted also that the lava has been described as having high levels of sulphur remaining in the lava

          • That 86 million tons per day , more than was put out by Pinatubo in one day by that small event,it is wrong by an order of magnitude just proved it with math.

    Equal to Jökulsá á Fjöllum river.

  7. I don’t want to be blamed on starting the jeep story again. But look at this new screenshot:

    Strange shiny dots everywhere. They come again, celebrating their weird “scientists”-cult?

  8. This seems to have got back to normal for the last few hours. Are there any experts who can explain the significance of this?

    Helps to put the picture in!

    • That also corrensponds with the bad weather that rolled through, so the cause was likely the weather and not the eruption.

  9. reasonable view of via the BBC if you can see the video. Google BBC NEWS Iceland issues new Bardarbunga volcano alert

  10. Looking from bardarbunga-2, there appears to be a lava flow a bit closer to the camera. If that is the case, and the camera is not situated right, we may lose the camera after a while.

  11. just a screencast for those that can’t access to Mila site (19.35h):

    DragonEdit: removed link that only linked to advertising for that site. If you have an interesting screenshot, please try again. Pls. also remember not to link to content that requires login. #DraGra

  12. All this begs the question… what are the earthquakes doing? Starting to slow down, or still popping off at a pretty good clip? Carl, what are the chances at this point that the mantle will at some point will come into play?

    • The background auto-plot earthquake activity had slowed down as the eruption began, you could actually see some “breaks” in the constant blue on Vat that’s been running for two weeks. That seems to have picked back up now.

      There remain large quakes in Bardarbunga caldera and there is an increasing concentration of small quakes with good confidence *NE* of Askja.

  13. Another question, is it still getting longer? And if so, what will happen when it starts interacting with the nearby river? Ash and explosions?

  14. Gisli Olafsson ‏@gislio 3m

    Scientists have revised amount of magma coming up to 250 m3/s – the lava is flowing NE at a rate of 1/2-1 m/minute

  15. Yepp, a nice flood basalt running now with a visible lava lake in the forefront.

    Even though this is far from Laki scale it is still a significant eruption.

      • And just what do you mean by that Inge? That it is not an eruption on the scale of the Siberian or Deccan traps? Or do you refer to the composition of the erupted lavas?

  16. I will re-post this to answer the “it’s bigger”, “it’s smaller” debate that happens each page.

    “Here is a quick composite with reference points marked for features and you can see that the extent of the activity is less this afternoon (bottom pic) than this morning (top pic).”

    The activity has reduced in the northern section, lava fountains appear to be similar in size throughout the day. I don’t see any difference between now and a few hours ago when I did these screenies but go ahead and do a similar exercise if you like.

    Lava flow more obvious now though.

  17. My son’s loving this! He and I watched Eyafjallajokull, and now he’s seeing a rift eruption forming. I sit back and nod in wisdom murmuring about the Krafla fires pretending to be a wise old volcanologist. Got to get some mileage out of being a dad… 🙂 More seriously – this is fascinating viewing and yes, I’ve seen some headlights in the valley. I just wish I could be there with the scientists. Good luck to them!

    • I’m older than many on here, and my fascination with Iceland in general and vulcanology in particular started with the eruption which created Surtsey around 1964. It got regular footage on newsreels in the UK (Good old Pathe News at the cinema) at the time. Then came the heroic battle to save the harbour at Heimaey in 1973 and I was hooked.

      I still haven’t been to Iceland, and my wife and I are probably a little too old for hiking now (plus I have various metal bits now which have replaced my original hips), so we are probably going to opt for a cruise to Iceland next year.

  18. I made this zoom this morning. I’m not completely sure for the fissure location. The date scale is wrong; latest data 31/08

    • It was smaller than todays event. But it was a persistant bugger.
      Heimaey was a fissure eruption, but not a rifting fissure eruption.

      • Thanks for that Carl. That certainly gives me a perspective as to the scale of the present activity . I remember the 1973 eruption well and was awed by both the pictures of the eruption and the amazing response by the people.

  19. Testing – trying to post a full-screen resolution screenshot, so bear with me if this shows extremelly big (if so, I’ll fix it…) – ETA: ok, it doesn’t show too big, but click on the image and you’ll get the original full screen version.

  20. Has anybody flown over today and taken footage? I haven’t seen any reports of any, but I might well have missed it. I wonder, because it looks to me like there is something going on behind the erupting fissure we can see, more distant puffs of smoke/steam that seem to be parallel with the main fissure. I’d love to see what the area looks like from the air right now – or even earlier today,

    • IMO reported that a flyover wasn’t possible due to the weather. Icidentally, they also stated that the eruption started just after 4.00 am and that it was first visible on the webcam at 5.51 am (which was when it was reported in here). The scientists were out observing it at 5.15 am.
