Still seems to be really active.

Here is the live stream someone posted a few days ago so people don't have to go back and find it again.

I wasn't much wrong saying 5.5 will happen within 24 hours. The quake was not 5.5, but 5.1 but still inside the caldera. Now expect more, maybe some aftershakes. This is result of collapsing caldera. Only 2 kilometers deep!

EDIT: Lowered back to 4.9 magnitude.

Thebel, I agree with you that we are seeing the ring collapse of the caldera roof.
I've been following the conversation in the comments at VolcanoCafe, under Carl's most excellent article. Here are his thoughts following this most recent quake at Bardarbunga:

Caldera blocking.
It is a bit worrisome. If this goes on sooner or later the roof on top of the magma reservoir will crack and water and ice will pour down into the hot magma chamber.

That could be one heck of a phraetic eruption. And what will happen with this expanding dike intrusion is anyone's guess.
It could just stop and not erupt, it could hook up with the smaller, but more explosive magma under Askja, or the dike could pull magma directly from the mantle below, and fissure erupt for an unknown amount of time.
Just some of the possibilities.

Interesting times in Iceland...

why do I have the forming of the russian traps ages ago in my mind ?????a reply to: Thebel

So with the roof collapsing.........just guessing 70 square km of ice at least 1/4km thick plus falling into the lava - and then water expands 900 times its volume instantly .....................!!!!!!!!

remember the collapsing of krakatau the explosion was world wide hearable.....:-(a reply to: egoli

This is very concerning. A prediction was made on a website I have been following and maybe this belongs in earthquake predictions, but I think it fits here with the current activity.

These predictions are unfolding. We predicted a timeline of 8-21, the volcano begin to erupt on 8-23.

Iceland’s Volcano Bardarbunga : The Spirits have presented 3 specific dates recently, one of which we are expecting to relate to Iceland’s Volcano eruption. I asked for clarity on when Bardarbunga would erupt and they presented ‘1’, implying either clarity that it will in fact erupt or pointing to tomorrow 8/21. The dates they presented are:
8.21 which could be August 21st
7-27 which represents the 27th, no month provided
15 minutes which represents September 2nd or 3rd,

Here are all the different predictions that relate to Iceland’s Volcano. There are several predictions about this one event which implies it will be a major eruption, 787 could relate to a message of August:

Notes on 5-8-14 I had a visual of spirit pointing to a map of Greenland, Iceland, and the spirit said “this is coming very soon” – A reference to the Volcano eruption.

Notes on 5-6-14 “In comparison to its last eruption the volcano will erupt 3 times greater in a massive scale of fire and smoke, so much so that it will greatly affect those at a great distance.”

Since we are thinking about this: What happens when Lava & Ice Mix???

Experiment by Syracuse University

Would like to see this experiment done with lava pushed up from the bottom also.

Look at the size, the ice at one time was covering these Tuya’s?? Thick, Thick Ice.

further to my previous post: here
Damn the lava keeps moving the goal posts, its still going NE.
I've changed the center point 3 times now to get all the earthquake events on the image !

Someone else is probably doing some archiving of the IMO maps, I haven't seen it in a series yet though, and the IMO maps aren't this detailed either. Most of you already know whats been going on but I find it helpful to look at things overall and within a set timeline.

This morning I used up 325MB creating 100 hourly images for the GIF animation and still didn't get as far as the first M4.7!, and I'm going to run out of capped data soon before the end of the month and computer will slow right down
so I've done one based on 24 hour periods, its still just under 1MB, I may be able to compress the individual files and get it down a bit more.
Changed to circles too, the crosses made the images too data hungry.
Red circles are the current day shown,
White are the ghosts of the previous days and blue are the 4.7+ events

heres a screenshot of the last day (25th Aug)

Animation is here

a reply to: muzzy

wow. that animation is crazy! thanks for posting that. i'm trying to follow this but i'm pretty forgetful. is it going toward the other volcano? the one that has a short name that starts with an A (i think)?

a reply to: SeekingDepth

Yes, but that is open air. What would happen when enough hot air comes out of the collapsing caldera to melt ice in a glacier above it. This melt water then trickles down through the cracks into the closed caldera and meets the lava where it gets turned instantly into steam and cannot escape quickly enough. Water becomes a much larger volume of steam.

So instead of your video where there is plenty of open air for the steam to escape to safely, you have a cap of rock holding all that pressure in. It would wind up being more like this:



Eventually, all that steam would escape explosively removing the rock trying to keep it in.

It would be rather spectacular ... and rather large, possibly Krakatoa loud. Hopefully, if the cap on Bardarbunga collapses in, it does so before too much of the covering glacier melts into the magma chamber underneath its cap just for the sake of not getting too much material stuck in the air.

a reply to: pasiphae

Askja is the one you are thinking of, yes its headed that way.
The animation is a bit clumpy being 24 hours per image, the hourly one is much better, but I can't promise I'll ever complete it.
It shows the hesitation on the 22nd better, where the lava was trying to find a new course, eventually busting through on the 23rd in a more N direction offset to the main dike direction which was going NE.

a reply to: SeekingDepth

Silly unrelated question, (I apologize), what are they using to heat and pour the lava in that video?

That was awesome to watch lava and ice, but it was cool to watch them pour it also.

Another big one.

a reply to: Thebel

There you go.

A star for Katla too.

a reply to: ketsuko


Exactly, this is why I said I wished they would also do this kind of experiment with the lava coming up from below the ice.

The last link on my post from Popular Science talks about when lava melts through the glacier, a lot depends on the type of lava, and how there are two opposing camps on how this will affect the amount of ash

1. “One theory is that when lava hits ice, the steamy explosions that result break the ash into smaller bits. Smaller bits can travel farther in the air, which is bad news for airlines.”

2. The other line of thinking is that when lava hits ice, it generates a lot of steam, which condenses on the ash particles and makes them stick together, creating heavier aggregates that wouldn’t be able to fly very far.

Yes rather spectacular either way!

Found this, looks like several types of furnaces.
