the one on IMO is 24hrs ago

That is correct I would expect the 2 fresh green stars and the sizes to appear by tomorrow morning when they are manually checked, they have been taking a while lately because of the hubbub lol.

I would think they will be updated before 3 o'clock as they have a situation room sort of thing set up now due to the fracturing and depressions being found as that's the first signs we have seen that something is happening and magma may be coming closer to the surface now.

That's the cracks near Askja. It looks like a different angle to todays first pictures. Almost certain. Now fully certain checked the N 64.52,35 W016.54,67 near Askja

 

Re the picture:- All that land is going to drop into that void I think, then we will see the lava.

My thoughts exactly

 

Things seem to be starting to move now, if much meltwater gets down into the magma there will be real fireworks.

 

Can only watch and wait

[Rustynailer]

Askja has been rumbling a bit I think or rather something has near by just, it looks to have gone off of the scale:-

 

I can't seem to post pics atm I will keep trying hang on.....

Just found this I google translated it LOL:-   Land has sunk off glacier north of Dyngjujökul suggesting that dyke lies much higher than previously thought. About five kilometers long and one kilometer change itself has formed above the dyke in the hole lava Dyngjujökuls north and out of the sand .

Tiny sigkatlar also formed in the periphery Dyngjujökuls . Scientists were aware of these changes when flying over Vatnajokull with TF -SIF yesterday . Scheduled to fly back to the scene at nine in the morning.

 

http://www.ruv.is/frett/berggangurinn-mun-ofar-en-adur-var-talid  from this in Icelandic which Google translate has big issues with

 

Latest IMO, one can see the Mag 5 quite clearly also another quite big one just at Askja.  

 

Here is the latest news http://www.ruv.is/frett/seismic-activity-near-the-askja-caldera   http://www.ruv.is/frett/possible-eruption-near-bardarbunga

 

 

I think the fissure at Dyngjujökul may have fallen in a bit and will be if we are lucky show some lava at the bottom, I would imagine it is quite fluid like Hawaii so it will be sloping about eroding the sides of the gully like sand on the beach.....

 

Update on all the EQ's up to now that are verified correct by IMO, they are one hour behind us.

http://www.livefromiceland.is/webcams/bardarbunga/  The "dust" that is being blown across the screen may in fact be from the fissure, it could be gas and fine ash, volcanoes do not give of smoke unless they physically burn something like a tree or a house.

 

People have been saying this is a dust storm for days in fact it is now accepted by some none experts that because of its position right over the swarm it is highly likely it is connected with it.....It was raining and still doing it the other day LOL these experts aught to have less blinkered vision   We will see..... A map on Carls site seems to show the "dust" exactly over the fissure EQ swarm, lovely. Still plenty of naysayers though.

Don't suppose it's possible that that these cracks/caldrons in the ice are the result of a eruption back when increased harmonic tremor led the Icelandic Met to suspect a small eruption was occurring, or do we know this tremor occurred in a different location?. I assume the area was flown over after then too so this is more recent?

 

Have noticed perhaps a slight increase in small EQ's around the Bardarbunga caldera as well as the bigger ones we're seeing, and also near to Askja, though perhaps these are just aftershocks to the bigger quakes. However maybe the subsidence/ring faulting allowed a small amount of magma to be 'squeezed up' which caused the melt?

 

As for fissure eruptions I could be wrong but doubt they tend to occur with the 'ground falling into a void', or being able to look down and see lava sat at the bottom at least before any eruption? If a connection to the surface opens up the magma is likely to be forced up and out by higher pressure below.  So mainly just a crack opens and you get lava flowing/fountaining out, on a small scale if a crack split and re-joined maybe the small section of cutoff land could 'cave in'?

 

^ I think if a fissure eruption had been occurring for days the IMO or someone would know about it..

The Icelandic Met Office has within the last few seconds issued a Warning on yet another Volcano in Iceland. 

A YELLOW warning has been issued for the Askja volcano, this means - The Volcano is exhibiting signs of elevated unrest above known background level.

The warning comes as Magma intrusion (dyke) from the Bárðarbunga Volcano has reached Askja.

This is a developing situation and this information may be outdated very quickly

Rather nifty little link showing the quakes in 3D

Was wondering if they would put Askja on yellow alert soon.

 

This appears to show the cauldrons and certainly shows some rather interesting cracks in an old lava field north of the Glacier. http://ruv.is/frett/sprungur-i-holuhrauni-a-myndbandi The way they cross a streams/recent fluvial sediment deposits in the video and the preview image show they are new and caused by this event.

 

Likely caused by stress changes due to the intruding dyke though not forming a continuous link to it yet as there is a lack of an eruption. If one was occurring/had occurred these flights should have discovered it.

Not sure if seen yet

Interesting though

I have not heard John Freeman so confident about the eruption before! Here is an extract from his site:

 

The situation is extremely dynamic and is going to change fast in next 24 to 48 hours. I am now close to 80% sure that an eruption is going to take place in both Askja volcano and Bárðarbunga volcano, since minor eruptions have been taking place under the glacier already.

So we have a few more M4+ quakes, then it all seems to settle for a while. After that 'Rinse and Repeat' But all the time the fissures are moving apart.

I wonder whether we will have weeks of this before the final outcome.

At least the jet stream isn't coming straight at the UK

i see the shocks  are coming a minute space  now

[The PIT]

Well it seems that the dike has stopped moving north this maybe as far as it can go or it's held up by stronger rocks and trying to find another way forward. We should know by tomorrow.

How long before we seen anything on the surface. We may not it may all stay below the ice cap. Hopefully it'll show itself very soon.

Looks like I was wrong about the dust on the Mila cam, arr well such is life. My apologies everybody

 

^^^ that looks like something John on the :-

The dark ice and cracks, this rift eruption should in theory develop gradually, with worrying violent peaks of activity and lulls for perhaps weeks.

People may worry, all I can say is rather have this than an alarming mutation of Ebola which may happen.....

I have a preference for the volcanic rift eruption thanks

 

Seriously though I hope this is not a Laki, just a small one, Krafla fires will do me, a once in an Internet lifetime event

I remember the Krafla fires when I was a kid and all was well in the world, great even on a black and white TV that stopped transmitting at around midnight.....

 

 

Errm better point out the picture is of the Krafla fires eruption from long, long ago before the Internet.

I think that if it has met an obstruction, the magma keeps pumping and the level raises and backs up, then flows out or along the next convenient crack or void like Hawaii. If it is blocked 100% which I doubt given the complex geology, it keeps pressurizing till it breaks out in a more violent fashion.

The tremor says its still pumping so do the quakes.

 

There is one thing though considering all the water about, flowing down cracks in the actual plumbing of the three volcanoes Ask, Bada and Grims,..... no steam or explosions.

Call it a wild theory, but what if there was no magma doing this, only the rift actually rifting(cracking) the magma may not ave arrived yet or more strikingly even formed formed yet. The pressure loss to the depths of the earth caused by this fissure/crack must be vast. I think it is what they call decompression melting, mmmm I will have to ponder that further.
