iceland Bárðarbunga and Askja - Volcanic Activity

[vladthemert]

how much more 5 + magnitudes can that rim withstand.  It must be seriously weakened last few days.

 

Swebby not sure saw those earlier was quite a bit kick off earlier there was big discussion on forum if it was dust storm or it extended the rift it did look white which suggested steam melting ice

Crack/fissure  may be past Askja and doing its own thing.....To the NE I thik

You'll be surprised how much stress these can take, there are so many factors that can affect the system, slip angles, ice cover, wedge shape.  You could see as many as another 20 at M5, but remember that's only 8 at M5.3 or 2 at M6.  The fact that earthquakes are measured on a log scale means that an M5 releases 1,000 times the energy of an M2

to me  that looks  like steam  coming from that cam  now  not  dust

[tinybill]

could she be ready  to blow soon!!

We've just had a 3.7 (initial estimate) http://en.vedur.is/earthquakes-and-volcanism/earthquakes/

Definite uptick on the tremor graphs

Can only just see it but it's there  Sorry about the fuzziness, it's a screenshot of a youtube feed

Shown clearly here, look earlier what has not been shown on the Link you gave, quite frightening. Bitwixt 17 and 18Z Iceland time, Too complex to be revised at all. A composite Mag will be given later, say 5^..... Bet there is some steam/gas with that sand on the Mila cam's

 

Latest revisions at file 2  Break to the right?...Too early to say but.....

 

Nasty weather tomorrow, Iceland will be staying inside on computer and TV generally, good thing too. Just in case.

Not sure if posted yet

Partial reason to take note of a possible eruption ?

Just a quick point

When i say no one knows what happens next does not mean

We cannot talk about whats happening and give our opinions

Its all quite fascinating to watch

I just think tonight could be the kickoff, how long to half time?  I have no idea

Why do you think there will be an eruption tonight?

[tinybill]

GN  ALL see  you all in the  morning what  time do it get dark in Iceland  just looking  at  the cam that all still light!!

[NorthNorfolkWeather]

Why do you think there will be an eruption tonight?

Probably vain wishful thinking

 

But

 

Many of the quakes, although small, seem to have been at less than 5 km deep, that suggests that some magma is trying to feed to the surface.  I think the biggest thing is how much gas is in the magma, if it's highly gassed then we'll have explosive decompression and that will rip the fissure.

 

The other point that's been made is the strength of the quakes at the main Cauldera, if they have seriously weakened the surrounding geology, then either a flank collapse or a Caulera collapse coun't be ruled out

 

There again, I could to completely wrong

[Rustynailer]

Hekla strain meter is creeping up slowly I am worried that people may get caught up in this, I think Iceland may need help if the poo hits the fan here.

Lets hope it goes away for a few  100's years just like that, it can. Teak no notice i worry out of hand sometimes.....

 

Sorry wasnt paying attention large jolt just.

Thanks. To me things appear slightly calmer tonight.

That can easily change of course.

It must have been a car as it moved to the right and disappeared.

[Shell Rawcliffe]

yeah thats it..

 

 

lost the link now, typical...

I thought it was car headlights but now I'm not so sure.

[Shell Rawcliffe]

The cam keeps panning left and right now so cant guess any kind of distance to see if it is a car or not.
