Bárðarbunga and Askja - Volcanic Activity

Recommended Posts


Sorry if already posted but that video is quite an eye opener

Its those rivers why has the water not exploded when it falls into those cracks and sinks down? I am sure the magma has not arrived yet.

Breath taking when viewed from the plane most prob'


B/W the The edge Dyngjujökull by Holuhraun, view to the north. photo on todays IMO update is captioned wrong its looking South actually, over worked IMO employees poor souls.....


Oh god my letters have gone small now  :closedeyes:


Oh there is one thing the IMO on their update today the picture titled The edge Dyngjujökull by Holuhraun,  Could somebody please take that silly 2001 0.1 megapixel camera off of them and give them a DSLR  :nonono:

I am still trying to understand what is happening here but there does seem to be a little confusing information going on. Before I express any thoughts, understand that I am not a volcanologist and th

Did you see the beautiful picture with the eruption glow and northern lights giving surreal lighting effects.   The eruption seen from Jökulsarlón south of Vatnajökull glacier.  (Martin Schultz,

This is my favourite (from elsewhere) to date - very atmospheric.

Todays summary from the Icelandic meto office


28th August 2014 18:14 - from geoscientist on duty

Since midnight over 1100 earthquakes have been detected by the automatic system. The dyke does not appear to have migrated further north since noon. The main activity is in the dyke and at similar depth as before (8-12km). One earthquake of M5 occurred at 08:13 AM by the northern rim of the Bardarbunga caldera. Two minutes earlier (08:11) another event of M3.9 occurred at a similar location. A few earthquakes were detected near Askja, the biggest one of M2.7.

Dyngjujökull - flight today

Cracks can be seen, e.g. by the little lake in the center of the photo, and they stretch towards north away from the lake. White streaks below left are probably cracks in the glacial ice.

28th August 2014 12:35 - from of the Scientific Advisory Board

Scientists from the Icelandic Meteorological Office and the Institute of Earth Sciences, together with representatives of the Civil Protection in Iceland, met today to discuss the on-going unrest at the Bárðarbunga volcano.

Conclusions of the Scientific Advisory Board:
  • This morning, there was a flight over the Bárðarbunga area and the surface of the glacier was surveyed. No changes to the ice crevasses southeast of Bárðarbunga, that were seenyesterday evening, were observed. These crevasses were likely formed due to melting at the ice bottom.
  • The depressions have been located southeast of the Bárðarbunga caldera, in all likelihood within the water divide of the river Jökulsá á Fjöllum. There are three circular crevasse formations, about 5 km in total length. The ice thickness in the area is 400-600 m.
  • The water level in Grímsvötn Lake has been surveyed and has likely risen by about 5-10 m in the last days, which corresponds to an addition of 10-30 million m³ of water in the lake. A slight increase in conductivity in Köldukvísl River was measured this morning, but the cause is yet unknown. No change has been measured in the Hágöngulón lagoon, Jökulsá River and Skjálfandi River. It is assumed, that the water from the cauldron has flowed into the Grímsvötn Lake or the river Jökulsá á Fjöllum.
  • The seismic activity is similar to that of the last days. Around midnight, three earthquakes of magnitude around 4 were recorded and one of magnitude 5 at 08:13 this morning, all located within the Bárðarbunga caldera.
  • Shortly before 08:00 this morning, there was a slight increase in seismic activity in the Askja volcano. Changes in the stress field due to expansion caused by the dyke have an effect on the Askja area.
  • Since yesterday, the length of the dyke under Dyngjujökull has increased by 1-1.5 km to the north, which is considerably less than in the last days. The dyke has now reached the fissure system of the Askja volcano and GPS measurements indicate that the area there is greatly affected.
  • The conclusions from the meeting of the Scientific Advisory Board of the Icelandic Civil Protection will continue to be published at around noon, after the meeting, if necessary.
From the Icelandic Met Office:

The Aviation Colour Code remains at the ‘orange' level for Bárðarbunga.

28th August 2014 06:17 - from geoscientist on duty

Activity in the Bardarbunga area 00:00-06:00 August 28 2014.

Activity continues in similar manner as before. It was slightly less then the night before.

Two events in Bardarbunga recorded, magnitude 4.1 and 4 at 1:30 and 3:30 resp.

Most events recorded were located within the northernmost 10 km of the dike and few small
earthquakes around Askja.

Total events automatically detected from midnight until now are 400.

Maybe dust storms were something else


This area is well known for dust plumes - a combination of geological and meteorological processes at work. Page 13 in this document pictures very similar to what we have seen on camera. I would wonder if there is now an added component of heat from the ground causing additional thermal rising.

We have some flaring magma in the valley







Jón Frímann mentioned something could happen in the next few hours,how right he was.




is it car headlights or magma??

That is not car headlights,look at the flare off it(smudgy to the top right)

Jon Firmann says yes, eruption on dyke.

Definitely a lava fountain, seems the dyke has found a weakness to the surface and only time will tell if it manages to fissure. The diffuse 'glow' gives away the source as being a eruption other than a consistent light source such as headlights or artifical light, bearing in mind the cam is some 25+ miles away from the Baroarbunga caldera itself.

Well there we have it.

Did notice a M3.1 quake only about 1-2km depth along with some other 2+ ones in the evening so maybe that was related.



Edit: confirmed at the top of the Icelandic Met Office website: http://en.vedur.is/earthquakes-and-volcanism/articles/nr/2947
