I'm going to assuming that's not good news.

Askja is known to have erupted with a type of magma that causes explosive eruptions. The magma from Bardarbunga is now starting to enter into the Askja volcanic area, so one theory is that this mixing of magma could trigger an explosive eruption at Askja. But even just the stress and deformation caused by the magma may itself lead to changes. Nobody really knows what will happen, quite possibly nothing, but this is unprecedented activity in this area in modern times so you have to keep an open mind.

A great person to follow on Twitter. You will see photos with lots of volcanic areas. Thorbjorg Agustsdott is in the exclusion area today.

Just spotted this blog:Update on Bárðarbunga and Askja volcanoes at 13:34 UTC
August 28th, 2014 by Jón Frímann

Send to Kindle
This is a none picture update on Askja and Bárðarbunga volcanoes. The reason for this none picture update is that I haven’t had time to work on the images yet. This is the first time this has happened in Iceland since modern recording started. What is going to come out of this I do not know yet.

If you are in the area. Please don’t go into the closed area. There are fines for during so and it is also extremely dangerous since we don’t know properly what happens and risk of sudden flood is high and growing. Eruption might start at any time without warning, both outside the glacier and inside the glacier. If an eruption takes place in a glacier covered area, that means sudden glacier flood that are going to kill you if you are in flood path. In such glacier flood it is not just mud, volcano material, but also an ice bergs that are larger than 5 floor houses. If you get lost in such flood, the chance of being rescued from such flood are none. If you want to watch what is now unfolding do so at the save distance, this show is going to big according to my earliest estimate and guess work (not going to publish that here).

Askja volcano

The dyke from Bárðarbunga volcano has entered Askja volcano. Not the fissure swarm, the volcano it self.
Askja volcano status has been elevated to Yellow.
Bárðarbunga volcano

Cauldrons in Vatnajökull glacier that is on top of Bárðarbunga volcano have not grown during the night.
The water seems to be flowing into Grímsvötn (Grímsfjall volcano) lake. It has risen close to 15 meters in the past few days.
Earthquake activity is high. Both in the main volcano were a magnitude 5,4 earthquake (EMSC magnitude, USGS magnitude) took place today (28-August-2014) at 08:13 UTC. The earthquake took place in the caldera rim as most of the large earthquakes have happened.
Over 1300 earthquakes happened yesterday in the north end of the dyke swarm.
Cracks have started to happen in the crust above the dyke. This means the dyke is getting wider and is higher up in the crust then suggested by earthquake activity. There are reports of small cauldrons in Dyngjujökull glacier in the area, in the place were the glacier is thinnest and ending.
Harmonic tremor remains high on all SIL stations around Bárðarbunga volcano.
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.

Previous post: Unclear what is happening in Bárðarbunga volcano

rickdangerouss

I would not agree with the 24-48 hrs, I read that via his Blog. Nothing in my view has changed the chances of anything dynamic and change in That time scale.

I would agree with what he typed, eruptions are going to take place in both Askja volcano and Bárðarbunga volcano, just not highly likely in the coming days, weeks, months or even years. Wait and see.

I follow Eric's blog too.

The vedur / en.vedur servers are VITAL to the Icelandic authorities responsible for Public Safety. Do not UNDER ANY CIRCUMSTANCE post a link / picture here or on ANY other website as this can cause and has caused their main server to crash!!! .

I have been guilty of this via posting a few links on this site and twitter, not many. This request was sent to myself, so I am posting it hear, due to a number of people do follow up on that site.

Now, that's interesting. I don't remember them doing that when Eyjafjallajokull or Grimsvotn erupted, and there were plenty of links posted then. Volcano Cafe were stopping people from posting such links earlier today and I hadn't figured out why... Guess we know now.
Regardless of their assurances that nothing may come of this, it would indicate to me that they're pretty worried.

Probably down to the fact that there has been an exponential increase in the number of active devices that open up every link when a page is opened, rather than static links that the user chooses to open.

They really need to set up a number of proxy servers to handle the traffic, but I doubt that such a thing is high on their priority list.

A number of cloud support companies, could provide that bandwidth ramp on a temp basis, I understand, the budget would be required to be adjusted.

Magma intrusion (dyke) under #Holuhraun (north of #Dyngjujokull) is at 2km depth according to @Vedurstofan #Bardarbunga #ashtag

maquiladora

At the current rate, the magma intrusion from Bardarbunga could penetrate the magma chamber of Askja volcano in around 5 days, or less if it speeds up.

maquiladora

Bardarbunga webcam appears to be showing what looks like lava. The magma intrusion may have reached the surface at this point between the glacier and Askja.

No confirmation from IMO.

Edit : Confirmed.

Aviation code downgraded to orange again. Looks like it was a short, small fissure, maybe similar to what happened under the glacier a few days ago that caused the melting.

I wouldn't be surprised if we saw more episodes like this happen on and off at different points.

I have absolutely no idea about volcanoes could somebody please explain what would the effects be if this volcano erupted?

stooge

It depends on the size and type of eruption. Anything from something slightly bigger than a large fart to a full scale world climate change over the next few years. Your guess is as good a most peoples at this stage.

If I was a betting man I would say a gradual small scale eruption over a week or two with medium ejections of ash causing some disruption to north atlantic airspace and severe regional disruption in Iceland, with no major noticeable impact on climate elsewhere.

The best thing, in my opinion, about volcanoes is their unpredictability!

Bear in mind that before the ash cloud debacle in 2010, this eruption wouldn't have been worth a mention except in the specialist press.

Yes.

A magnitude M5.4 earthquake occurred at 07:03 at the southern rim of Bárðarbunga caldera. Several events of similar size have occurred around the caldera rim in recent days. They are interpreted as possibly being related to subsidence of the volcano due to volume decrease in the magma chamber beneath.

IMO also say that the magma intrusion now appears to have stopped.

there is no sign now of northwards migration of the intrusion

So for the moment at least, there is no chance of the magma reaching Askja's magma chamber.

rickdangerouss

Eruption Bárðarbunga is now considered more likely than before. This was stated at a meeting of the Council of Coordination of scientists today. Seismic we Bárðarbunga is still very high, the highest has been 15 miles long area centered on the edge Dyngjujökuls.

http://www.ruv.is/frett/gos-i-bardarbungu-talid-liklegra-en-adur



About 0.65-0.90 cubic km, depending on what model is followed. If the events unfold and a fissure happens, small is no longer in view, medium to Large with amount now, if current rate this continues for a few months. I have read from different sites, the influx is slowing in some spots, but increasing under Bárðarbunga and the local area.

450lbs of lava was poured on to a 6” thick ice structure measuring 4’ by 12’

Another fissure, just started. Do not know if the same area. Only good thing about been in work at this time on a Sunday.

maquiladora

Same place as last time. The ex-hurricane is causing strong winds, kicking up dust now, so it's hard to get a good view, but it appears to be mostly steam now so it may be tapering out again.

This was earlier :

These type of small fissure eruptions could go on and off for weeks, months even years.

Could be a real boon for Iceland's tourist industry. Direct flights from Belfast to Iceland happen to start in December by the way.

rickdangerouss

Some small possible evidence that the mantle is involved.

http://earthice.hi.is/chemical_composition_basalt_erupted_29_august_2014_through_1797ad_holuhraun_linear_vent_system_north

This the type of lava from the fissure at this time.

http://en.wikipedia.org/wiki/Tholeiitic_magma_series

I read that "Sulphur traps, as the time in the crust is to short for SO2 degassing to take place fully."

So, maybe a new volcano is starting out?

Latest updates from the site below.

Thorbjörg Agustsdottir on her Twitter account,

https://twitter.com/fencingtobba

“30 m high lava fountains, 1,5k long eruptive fissure, several lava flows, at least 800 m long and 100 m wide.”

maquiladora

Visible again on this camera. Pity it's not a bit closer.

http://www.livefromiceland.is/webcams/bardarbunga-2/

Hopefully the weather stays clear, should look nice after dark if it continues.

maquiladora

Going through a more active phase again. These lava fountains are taller than they look here.

maquiladora

The individual lava fountains are up to 60-70m high. You can see the glowing edge of the lava flood out in front of the fissure now too.

hatrickpatrick

Been researching this for a while and just wondering what are people's thoughts on the theory that the hotspot currently underlying Iceland is the same hotspot which began its life with the Siberian Traps flood basalt eruption c.250m years ago and was the likely catalyst for the P-T mass extinction?

As flood basalt eruptions tend to mark the beginning of a hot spot's life, the two competing theories seem to be that the Siberian Traps mantle plume ultimately became either the Iceland hotspot or the Hawaii hotspot, but as it was buried under deep continental crust for much of its history, it doesn't have a consistent hotspot chain to trace its development over time.

Looking quite nice now:

High levels of SO2 detected from the eruption earlier today, but not an issue unless you are in the area.

Lets hope it does not end up like this.

Lava is in the green. Thanks to the Institute of Earth Sciences, University of Iceland for the map.

Large cauldron has formed in Dyngjujökull glacier. Said to be 1km wide. Depth unknown.

Still interesting times ahead.

An eruption may be starting up the glacier. Hold onto your hats, there could be a rather large bang, and soon.

Edit : Maybe not, the tremor picked up but has started to drop again, so maybe not soon :P
