Bárðarbunga volcano update Monday 17-November-2014

There has not been any major change in the eruption in Holuhraun. Latest reports are that the lava field is now 74 square kilometres in size. While the eruption is smaller than it was when it started, it is still considered a large eruption based on volume of lava that is now erupting. The crater rim was according to last news around 60 meters high, it might have lowered from last report that I did hear that stated it was around 100 meters high. Since the rim is made out of loose material it is unstable and might suffer from collapses at regular time intervals. SO2 pollution continues to be a big issue in Iceland depending on wind. Once I am back in Iceland I am going to start posting pictures of it for those days it is going to be in the part of Iceland where I am going to be living (north-west Iceland).

Earthquake activity remains the same as before in Bárðarbunga volcano. Largest earthquake on Sunday (16-November-2014) had the magnitude of 5,4. Earthquake activity is heavy at times in Bárðarbunga volcano, after a large earthquake takes place (above magnitude 5,0) earthquake activity drops for few hours in Bárðarbunga volcano, this appears to be normal. The rate of subsidence is about the same, it has slowed down in the centre of the caldera according to the news from today.

Bárðarbunga volcano update Wednesday 12-November-2014

Eruption activity continued in Holuhraun at the same rate as on Monday (10-November-2014) and yesterday (Tuesday 11-November-2014). While bad weather has making observation of the eruption in Holuhraun difficult and close to impossible there are no signs of the eruption ending any time soon. A lava lake has now formed that is around 400 meters long and 100 meters wide. This is the first lava lake in Iceland in a long time. I don’t know when last lava lake existed in Iceland, but that was a while ago.

Earthquake activity in Bárðarbunga volcano continues as it has been doing for the past two and half months. This means that the caldera continues to subside at unchanged rate. I do not know how much the area has grown that is now subsiding, I think there is limited information on that due to limited access to this area in the winter time. At the moment nothing seems to be changing and GPS data is supporting that view of mine. Comments on this blog and blogs posts by people how have gone to the eruption site in recent days say that new fractures are appearing south of current eruption crater. This means that rifting is continuing, this also means that new eruption south of current crater might start at any time without warning. Since magma is at shallow depth at this location, with depth being only 1 – 2 km at most, it is possible that it might even be at shallower depth closest to the eruption crater (but has not erupted yet).

Tungafellsjökull volcano

There has been minor increase in earthquake activity in Tungafellsjökull volcano. At the moment this looks just like a tectonic stresses are adjusting to all the changes in Bárðarbunga volcano. Earthquake activity in Tungafellsjökull volcano might increase in next few days or weeks. I don’t expect any eruption to take place at this point in time.

Bad weather warning

For the next two days there is going to be bad weather in Iceland. This means that detection of earthquakes is going to be limited in Holuhraun and around Bárðarbunga volcano. This means that only largest of earthquakes are going to be properly detected. Visibility to the eruption site on web-cameras is not going to be awful to none due to the snowstorm that I expect might follow this storm in the highland (it might rain, but I am not sure on that detail yet). It is storm season in Iceland so expect a lot of storms all winter.

Bárðarbunga volcano update for Friday 31-October-2014

Not much has changed since Wednesday (29-October-2014) update in Bárðarbunga volcano. Earthquake activity continues as it has been doing for the past two months.

Strongest earthquakes for the past 24 hours have the magnitude of 5,3 and 5,2. Other earthquakes have been smaller. There is no change in earthquake activity in Bárðarbunga volcano and the caldera continues to drop around 40cm/day at the moment. Current SO2 output levels are around 20,000 to 40,000 tons/daily of SO2 from the eruption in Holuhraun. Bad weather has blocked proper earthquake detection and monitoring of the eruption in Holuhraun and of Bárðarbunga volcano. The weather is going to be extremely bad in Iceland for the next 6 – 10 hours. Other than this I don’t have any more news of Bárðarbunga volcano eruption.
