Uncertainty level declared because of magma intrusion in mountain named Þorbjörn on Reykjanes peninsula

Icelandic Met Office has declared uncertainty level because of inflation in the mountain called Þorbjörn (no Global Volcanism Profile) that started on 21st of January 2020. This inflation has been followed by earthquake swarm activity that is ongoing at the writing of this article. The inflation has been 2cm today (26-January-2020) and the estimated volume of magma is 0,001 km3 and that is possibly too small to erupt at the moment. The inflation is 3mm to 4mm a day at the writing of this article. This active area is just north of the village of Grindavík.

I’ll update this as best I can but I am currently in the progress of moving back to Iceland. But I don’t expect anything major to happen just yet. At least I hope that is what is going to happen. I plan on having my geophone network back by early March when I can fix the rollover problem the GPS clocks I am using are having.

Earthquake in Bárðarbunga volcano

Today (26-January-2020) at 14:25 UTC an earthquake with magnitude of Mw3,7 in Bárðarbunga volcano. This was a single earthquake but that does not rule out a second earthquake in Bárðarbunga volcano is going to happen in next few hours. That might not happen since a second earthquake doesn’t always appear.

This earthquake shows that Bárðarbunga volcano continues to inflate at fast speed. When next eruption is going to happen is impossible to know but shortest time between eruptions in Bárðarbunga volcano is just 3 to 8 years.
