Statement to all serious posters of this thread: In my view things are escalating fast in Bardarbunga region, so i decide that now on this thread will be ONLY to a serious following/discussion on this events. This is not the space to crazy theory discussions or even off topics of any type. If you want to do it, please open another thread... Thank you for your support, Luisport.

Rúv News is reporting that Icelandic Met Office installed a Accelerometer on top of Bárðarbunga volcano, in the same area as the GPS station is. They have been getting data for one week now. This suggests that magma is now only on 1 – 3 km depth, rather than 5 – 8 km depth as they thought earlier. This means that Bárðarbunga volcano can start erupting under the glacier without any warning at all given current earthquake activity.

In the RÚV emission [link to ruv.is] , they summarize the eruption up to now. It is a very big eruption, but still the quantity of lava produced during the Skaftáreldar eruption (Laki) was 14x the one of Holuhraun. But also acc. to professor Magnús Tumi Guðmundsson, this is the biggest eruption since then. Measured in DRE, it is about 5-6 x the quantity of the 2010 Eyjafjallajökull eruption.

Acc. to more accurate measurements of the lava quantity, the expert says, that it is rather difficult to do that, because of 1) the big surface covered by the lavas, 2) the gas emissions hindering scientists to approach it with instruments and 3) the often impaired visibility. [I think, here, Magnús Tumi also means the weather conditions, snow storms etc.]

Re. the connection between Bárðarbunga and Holuhraun, the subsidence measures now about 40m x 70 km2, which is less than the calculated magma quantity within the intrusion + the erupted magma quantity. The most probable explanation for the subsidence is though a connection between the subsidence and the eruption in Holuhraun. There is still the possibility of an eruption within the caldera, which would cause a big jökulhlaup and a big quantity of tephra output, it is necessary to be prepared for something like that, says Magnús Tumi.

Sent some coordinates to my son at Oxford and he gave me the formula. Something tells me it’ll have long blown before we get to the 26th March 2015. If the Holurhaun eruption stops then any magma support for the floor goes and that could accelerate the collapse.

I am really going to buy two gas masks. Seriously.
What you will read below is my most doom moment ever in this blog, and I have reasons for it.

It’s not the fissure that worries, not even it it’s a large event, or if the dike reaches Askja, but what it really worries me, is Bardarbunga caldera.

I reckon that a few more M5,8-M6 quakes, along with more draining of magma from within the caldera, and I think the caldera will start to collapse. That’s a powerful beating to the caldera, which by the way has not gone caldera for millenia.

We are already seeing extensive ring faulting, and quite large quakes. Total seismic energy release there has been already equivalent to a M6. About 25% of the threshold of what I think is necessary to pop the lid out, according to mine and Geolurking’s guessestimates. We could of course be wrong.

So, what to expect if it really goes caldera?

– A powerful VEI6 eruption, about 10+ km3 tephera (that’s several times more than Askja, Oraefajokull or the large eruptions of Hekla)
– Ash deposited all across Iceland. At least 1cm everywhere, and perhaps deposits many cms thick. Think 20cm or more. Icelanders migrating on emergency to Reykjavik. Farm sector of Iceland becomes impossible. Tourism too. Iceland suffers major economic losses, and it will be a stress daily life, dealing with so much ash. Many will just travel away. Because for many life in certain parts of Iceland will be impossible.
– Ash deposited in Scotland and Norway of a few mm. European disruption of airlines is massive.
nice try150; Worldwide disruption of climate. Severe cold winters. Cold summers. Large economic losses, and further social unrest, but overall it’s not the end of our western way of living, just a severe setback in some things.
nice try150; Definitively panic would appear because of airline disruption.

So this is not end of the world, but a nasty scenario. Especially for me. Trouble is we are getting within a reasonable percentage of likelihood for that. It’s not a far fetched scenario anymore. It is possible at the moment. And it’s progressing towards it. Albeit we do not know how much energy is required for that.

Seriously I don’t want to think about the possibility of magma hitting the caldera of Askja at the same time as Bardarbunga caldera shakes with M5s and a 40km fissure opens in between.

This is developing too quickly in one of the worst case scenario. And while I don’t wish to cause panic around (after all this is a public debate) we need to ponder about the possibility of such a scenario, how likely it is to develop, and what consequences it would have. But obviously we are entering a set of scenarios of which we know little about.

What would happen at the very worst? Two caldera eruptions, and a large rifting in between. That’s a VEI6 event, probably in the order of 10+ km3 released material, in form of lava and tephra. Not pleasant to have Iceland covered with cms of ash, and also much gas killing many sheep. And also a few mms over the British Isles or Scandinavia. One just has to look back in Iceland’s history to see how often such scenarios occurred.

So far cumulative seismic release does not point for a larger fissure. So that’s assuring. But the fissure is quickly propagating towards Askja and the conduit is already open at both Askja and between Bardarbunga caldera and the tip of the dike, currently outside of the ice cap.And worryingly the B caldera is showing large signs of strain, all around it.

 Quoting: Luisport
Irpsit August 24, 2014 at 18:53
GPS at DYNC shows 19cm west movement, and a reversal of the 5cm north movement, now it already moved 1cm south, this is because the dike is moving northwards.

Grimsvotn still continues at 8cm southwards.

I estimated around 35-40cm of rifting. That’s almost half a meter, and about 1/4th of a normal fissure eruption.

This means at this rate the eruption will likely happen around 1 month after the start of the rifting event. This is around 16th September. If it continues for a few months, then we will be into a Laki or Veidivotn-like scenario. If it erupts by September then it would be similar of the scale of 1862 rifting event, or slightly larger than Krafla fires.

There is a possibility that it erupts earlier, in smaller scale, when the dike reaches about 60km, as it loses intensity. Or otherwise it triggers an eruption at Askja. Or it continues for a longer time, and it triggers a caldera event at Bardarbunga.

At this point, everything is possible, all options are on the table.

Three outstanding facts are clear:
nice try150; ring faulting around Bardarbunga caldera: not good
nice try150; dike fissure is now 40km long, and already reaching out of the glacier.
– It is already inside Askja fissure swarm, and this rate it reaches the caldera within 4 days: also not good

Fourth thing, also not very good: a few quakes show up at Edlgjá. I am not sure about this, these have been showing up on and off the last few days (even before the Bardarbunga event). [link to volcanocafe.wordpress.com]

Fabulous article to read, that puts things into context and can give us a window of what it to come

[link to eps.mcgill.ca] off98%20and%20Gudmundsson,%202000.pdf

Basically, at a hotspot peak every 140 years, activity rises at Vatnajokull and there is at least one episode of rifting in Vatnajokull, one episode of rifting elsewhere in Iceland, and also seismic crises at same time in south Iceland transform zone. Sometimes the rifting occurs without eruptions too. Itnice try146;s like every 140 years, rifting occurs in most of Iceland for a few years or decades and then things go relatively quiet for about 50 to 80 years.

This peak is just around now. And this why we see this.

 Quoting: Luisport

For future memory...
Carl August 23, 2014 at 11:32
And the fissure is opening up now rapidly.
We currently have a fissure open from 20 to 2.5km, that would make magma rise straight up from the mantle to the top. Probably intense decompression melt driving what we are seeing now. It looks like the eruption will occur 13km due east of Kistufell. This means that this is not a normal fissure eruption that will take the magma out of the central volcano, instead the main bulk would come up directly from the mantle.
The fissure seems to be narrow enough in extension to follow in line with Irpsits idea above.

I expect that the first part will be explosive since it would contain evolved Bárdarbunga magma, but that it in a few hours would go down into a far less explosive stage as pristine mantle derived magma comes into play.
Also, the Glacier is not particularly thick there so expect it to pop up rather fast.

Caveat, I do not yet know 100 percent that it will blow at this stage.

Important update.

I can now tell you, at this level of activity, we still need to wait several weeks until we see a proper sized eruption. Unless a string of M5 quakes hits, then an eruption would just be hours away, if that number of M5 quakes is near 10 (or same equivalent cumulative seismic energy), or one M6 event or near that.

Why is this?

The GPS stations at both sides of the intrusion taking place at Bardarbunga show a lateral displacement of around 2cm per day (1cm/day in both directions).

During the last rifting event at Bardarbunga, the rifting displacement was around 1.5 meters (150cm) as the fissure opened, over some 15km. Let’s say we expect an event about half of it. To be on the conservative side. And 7km is just the same as Gjálp.

At this rate, we will need 35 days, to see a displacement of 75cm as the rift opens.

Total energy combined is probably equivalent to a M5. Until yesterday I calculated total energy to be about M4.5. Today it nears M5 (total cummulative seismic energy). That equates to a displacement of a few cms, which is what is actually taken place. Which is too little!

One M6 equates to a displacement of 50cm, so it is near what it is necessary to see such a fissure ripping apart of sufficient lenght; or a string of 10 quakes at M5.

Thus until this moment, only about 1/10th of the threshold energy has been released.

So this gives 10 times longer time, until we see an eruption of the type I assumed, if the current level of activity keeps.

But a few M5 quakes would quickly speed the process, to only a few days necessary.

So I predict to see either more 9 times of intrusions with the same sort of intensity (if such activity would now stop nice try150; which seems to be unlikely at the moment), or this intrusion continues for more 35 days (until mid September), or the energy increases until the level of several M5 or one M6 event (whitards current level of increasing activity is just a few days ahead). If this intrusion continues for some more days but then dies down, then we would still need another one or few repeats of same intensity, until a fissure event.

Consider this the threshold.
Now, you know when to expect the start of the eruption.

Simple maths.
Irpsit

August 18, 2014 at 20:01


Quakes are also not updated correctly. Besides the M4.5 event in 2:37, there was two quakes around M3.5 at 10:44 and 15:07. The list is just a mess, these two quakes should be revised.

The Bárdarbunga volcanic system is the largest in Iceland and it has erupted more lava than any other volcano on the planet in the last 10 000 years. The volcanic system is 200 kilometers long and 25 kilometers wide.

The central volcano has a seventy square kilometer caldera that is ten kilometers across. Technically it is a highly complex type of volcano that is a mixture between a shield volcano, a strato volcano, tuya formations, volcanic ridges, radial volcanic fissures and a truly astounding volcanic fissure swarm extending in a NNE/SSW direction out from the central volcano.

The largest effusive eruptions has come from the fissure swarm where the Thjorsahraun is the largest lava eruption on the planet in the last 10 000 years. The largest explosive eruption occurred in 1477 during the Veidivötn basalt flood eruption in the southern part of the fissure swarm. During that eruption a VEI-6 explosive eruption occurred in the caldera that was the largest explosive eruption in Iceland since Grimsvötn suffered another VEI-6 almost 10 000 years ago. The 1477 eruption is the largest explosive eruption in Iceland since settlement and also the second largest effusive eruption only bested by the Lakí eruption. I think I just set a new record in using the word “largest” in a single paragraph.
Bárdarbunga is understudied since very little was known about the volcano until satellite imagery revealed the true scale. The reason behind this is a combination between it being remote, it having had small and benign eruptions for the last 537 years. The small scale of the eruptions are probably due to damages to the volcanic chamber system in the caldera after the large explosive eruption in 1477. The last reason is that the entire volcano is covered in ice completely.

The last confirmed eruption in Bárdarbunga occurred in 1996 during the Gjálp eruption. That eruption was a short duration VEI-2 eruption with a 3.5km high eruption column. It is also possible that the entire Gjálp eruption was a radial fissure eruption from Bárdarbunga and that Grimsvötn erroneously had that eruption attributed to it. The jury is out on that one.

Bárdarbunga is also by far the most seismically active of the volcanoes on Iceland. Not in numbers, that is the Gódabunga Cryptodome near Katla Volcano, but in the amount of Cumulative Seismic Release. CSR is the same as the amount of earthquake energy released over time.

Unconfirmed eruption in Bárðarbunga volcano

Posted on August 16, 2014 by Jón Frímann

This information is going to get outdated quickly as more information is collected on this activity.

During all last week (Week 33) there has been a minor earthquake swarm in Bárðarbunga volcano. No other activity followed this minor earthquake activity during the week until last night (16-August-2014). During the night (around 02:20 UTC) a harmonic tremor started to appear on SIL stations around Bárðarbunga volcano. Following the appearance of the harmonic tremor earthquake activity started around 03:30 UTC. Largest earthquakes in this swarm have magnitude around 3,0 so far. Depth is around 5 to 10 km. During the night the earthquake swarm moved around in the volcano and is now more east then it first started. According to Rúv news the glacier around this part of Vatnajökull glacier is around 700 meters thick, so it going to take a major eruption to break the ice. This however also means that when a glacier flood starts in this area there is a high risk that is going to be large.


Currently the activity in Bárðabunga volcano is not stable, it does fluctuate a little. Besides this minor fluctuation it seems stable. Based on harmonic tremor signal and its range this does not appear to be a large eruption so far. That might change without warning. I do however expect larger earthquakes before any major volcano eruption in Bárðarbunga volcano. What seems to have happened is that a dike intrusion got to the surface and started this eruption, even if it is just small one at current time.

I am going to post update soon as more information gets available. This situation is going to change quickly and without much warning.

Today is different, few larger quakes, then it was more “quicker”. But we will see. I will be back with updates. Need time to asses the evidence. I do not expect “breaking news”, it may build up slowly and take a day or to to show on “top surface” (Glacier is 700 m thick)

Irpsit, watching Bardarbunga

Don’t think anything will happen today. That’s my gut.

But I think this is the run-up towards an eruption sometime in soon, could be this week, this month, this year or next few years at latest. Or maybe this is already a minor eruption taking place under the thick ice. It wouldn’t be the first time we wouldn’t be sure, and that it is actually taken place already under Vatnajokull.

Trouble is we do not know very well how Bardarbunga behaves, and even the well known Grimsvotn seems to surprise us too.

Well, the run-ups in different volcanoes are very different. Compare 3 or 4 quakes in Hekla leading to its eruption in 2000 (a quite silent sneaky volcano), with a similar situation to today’s when Fimmvorduhals-Eyjafjallajokull was about to erupt ( [link to www.mbl.is] (but remember the first eruption was a tiny fissure at VEI1), to several green stars for the 2011 VEI4 eruption of Grimsvotn, a swarm of quakes that came out of the blue ( [link to thetruthbehindthescenes.files.wordpress.com] and to a similar situation in Katla (several green stars), but in the context of continuous swarms over time, and no eruption took place ( [link to modernsurvivalblog.com]

A VEI1 to VEI2 could already be occuring under the ice. Or maybe this is the prelude to a larger eruption in soon.

If the eruption is a VEI1 or even a minor VEI2, then it could be remain hidden under the ice. And even melted water could only flood some weeks later. So we would never suspect an eruption, like it happen with Katla and Hamarinn in July 2011.

The Bárdarbunga volcanic system is the largest in Iceland and it has erupted more lava than any other volcano on the planet in the last 10 000 years. The volcanic system is 200 kilometers long and 25 kilometers wide.

The central volcano has a seventy square kilometer caldera that is ten kilometers across. Technically it is a highly complex type of volcano that is a mixture between a shield volcano, a strato volcano, tuya formations, volcanic ridges, radial volcanic fissures and a truly astounding volcanic fissure swarm extending in a NNE/SSW direction out from the central volcano.

The largest effusive eruptions has come from the fissure swarm where the Thjorsahraun is the largest lava eruption on the planet in the last 10 000 years. The largest explosive eruption occurred in 1477 during the Veidivötn basalt flood eruption in the southern part of the fissure swarm. During that eruption a VEI-6 explosive eruption occurred in the caldera that was the largest explosive eruption in Iceland since Grimsvötn suffered another VEI-6 almost 10 000 years ago. The 1477 eruption is the largest explosive eruption in Iceland since settlement and also the second largest effusive eruption only bested by the Lakí eruption. I think I just set a new record in using the word “largest” in a single paragraph.
Bárdarbunga is understudied since very little was known about the volcano until satellite imagery revealed the true scale. The reason behind this is a combination between it being remote, it having had small and benign eruptions for the last 537 years. The small scale of the eruptions are probably due to damages to the volcanic chamber system in the caldera after the large explosive eruption in 1477. The last reason is that the entire volcano is covered in ice completely.

The last confirmed eruption in Bárdarbunga occurred in 1996 during the Gjálp eruption. That eruption was a short duration VEI-2 eruption with a 3.5km high eruption column. It is also possible that the entire Gjálp eruption was a radial fissure eruption from Bárdarbunga and that Grimsvötn erroneously had that eruption attributed to it. The jury is out on that one.

Bárdarbunga is also by far the most seismically active of the volcanoes on Iceland. Not in numbers, that is the Gódabunga Cryptodome near Katla Volcano, but in the amount of Cumulative Seismic Release. CSR is the same as the amount of earthquake energy released over time.

The earthquake activity seems to have started near the Gjálp fissure where the eruption occurred in 1996 and now moved to the NE spot of the Bardarbunga caldera, near Kistufell, where intrusions have been happening for a long time.

Meanwhile they just updated the 4:15 quake to M3.1. Which is correct in my opinnion. It must be somewhere between a M3 and M3.5

There is a storm in Vatnajökull area today. This means smaller earthquakes are not being detected due to wind noise.
