Strong earthquake in Bárðarbunga volcano this morning

Today (28-May-2022) at 08:06 UTC an earthquake with magnitude of Mw4,4 or Mw4,7 (EMSC information can be found here) took place in Bárðarbunga volcano.

This earthquake activity is because of inflation in Bárðarbunga volcano magma chamber. That was emptied after the eruption in 2014 – 2015 and that resulted in collapse of Bárðarbunga volcano by drop of some 60 meters. This inflation now is reversing that process slowly. It is going to be decades until Bárðarbunga volcano erupts again because of this collapse.

On Thursday 26-may-2022 there was a strong earthquake on Reykjanes ridge

On Thursday 26-May-2022 at 20:11 UTC an earthquake with magnitude of Mw3,5. I think this earthquake was maybe felt in populated areas closest to the earthquake. This earthquake was out in the ocean, a good distance from land.

This earthquake possibly is part of the earthquake activity that is happening in Reykjanes peninsula and Reykjanes ridge. It is more difficult to know what is going on in the ocean, than on land.

Posts are going to get delayed for the next few days because I am moving to Denmark.
