Today (24. June 2023) an earthquake swarm started in Katla volcano. Largest earthquakes had magnitude of Mw3,8 and Mw3,3. Other earthquakes have been smaller. This earthquake swarm is ongoing but has slowed down since this morning.
At the writing of this article there is no clear sign that an eruption is about to happen. That might change without a warning. This earthquake activity might stop and nothing more is going to happen until next time. That is what has been going on for the last few months and years.
The swarm is situated in a fairly unusual spot, compared to earlier unrest. We have been used to seeing EQ activity closer to the northern rim of the caldera (closer to AUS station), not often in the center of it. This could evolve into a new, interesting chapter for Katla.
I’ve seen earthquake swarms in this location before. Happened a few years ago. That year in July a small eruption took place in Katla volcano. If that is going to happen now is just a wait and see situation.
