Earthquake in Vatnajökull mountains (part of Hekla volcano system)

Today (28. November 2023) at 05:56 UTC an earthquake with magnitude of Mw3,5 took place in Vatnafjöll mountain area. This is in a area that had a magnitude Mw5,0 earthquake few years ago. This might be an aftershock.

There was a small earthquake swarm following this earthquake. I haven’t seen any reports that this earthquake was felt by anyone.

Today (13-December-2021) at 16:04 UTC an earthquake swarm started in Vatnafjöll mountains. This looks like a aftershock activity from the Mw5,2 earthquake in this area few weeks back. Three earthquakes with magnitude above Mw3,0 took place. The earthquake magnitudes where Mw3,0 (at 16:04), magnitude Mw3,2 (at 16:07) and magnitude Mw3,5 (at 16:08).

There continues to be a risk of more aftershocks in this area. It remains a question if there is going to be a stronger earthquake activity in this area in next few weeks.
