Today (06-September-2022) at 13:19 UTC an earthquake with magnitude of Mw3,1 took place in Torfajökull volcano. This earthquake took place in the caldera rim. There were few other minor earthquakes in the same location.
This area of the Torfajökull volcano caldera has been having activity for several years. The amount of activity in this area goes up and down and for the longest time now, there hasn’t been anything going on there. What is going on in this area is unclear, since I don’t see any obvious signals that an volcano activity is about to start in this area. Torfajökull volcano does not erupt lava flows, since its magma are Andesitic magma and up to Rhyolitic magma types [Magma types on Wikipedia]. That results in a ash cloud eruption. Last eruption in Torfajökull volcano was in the year 1477, probably triggered by a dyke intrusion from Bárðarbunga volcano.
