Bárðarbunga daily update for 7-October-2014

This is the daily update for Bárðarbunga volcano on 6-October-2014.

I’m sorry for this late update. I’ve been more busy today then I planned. I did manage to solve one network problem that I was having. The other network problem that I am having is out of my reach it seems (It’s a problem with the ISP network connection to my end I think).

Status of Bárðarbunga volcano on 7-October-2014

  • The largest earthquake today had the magnitude of 5,5. It took place at 10:22 UTC. Other earthquakes that happened today where smaller. It seems that around 5 – 20 earthquakes that are larger then magnitude 3,0 happen every day now in Bárðarbunga volcano. This has been going on now for almost two months.
  • The eruption in Holuhraun continues far as I know. I am not sure on how large the lava field is today. Visibility has been poor to none today due to weather in this area at the moment.
  • Tourists are continuing to trying to kill them self by getting close to the eruption site. The newest case involves a millionaire (or billionaire?) from Kazakhstan that landed close the lava field. They where lucky that wind did not change direction while they where there. The amount of SO2 close to the eruption has been recorded going up to 130.000 μg/m³. That is good enough to kill instantly and melt people lungs (read up on that can be found here).  News item on this stunt can be found here.
  • I suspect that activity in the south part of Bárðarbunga volcano system is about to start. When it is going to start full force is impossible to know for sure.
  • It is a question of Tungnafellsjökull volcano is getting unstable due the unrest in Bárðarbunga volcano. It appears to be in the same rift area, even if it is in a different volcano.
  • Skrokkalda volcano appears to be stable for now (No GVP profile). This is important since Tungafellsjökull volcano fissure swarm extents into it and it is next to Bárðarbunga volcano fissure swarm. This volcano has no information on-line about it, besides what I have written about it. It is an active volcano, but has been dormant for a long time. Some hydrothermal activity might happen in it on the surface.
  • I don’t know how the status is on Hamarinn volcano (Loki-Fögrufjöll). I am however assuming that volcano to be unstable. It last erupted in July-2011 with a minor eruption that lasted some 8 to 10 hours in total. Eruptions in Hamarinn volcano happens without warning and without any earthquake activity, at least not high amount of earthquake activity far as I can tell.

If anything more happens I am going to add information about it here.
