Earthquake swarm in Katla volcano

Today (9. March 2023) an earthquake swarm started in Katla volcano. This earthquake swarm is ongoing and information in this article can go outdated quickly. Largest earthquakes at the writing of this article have a magnitude of Mw3,3 and Mw3,4. A swarm of smaller earthquakes is ongoing.

It is difficult to know for sure what is going on in Katla volcano. But this activity reminds me of what happened few years ago before an small eruption took place in Katla volcano. If that is going to happen now I don’t know. I’ll post information when I know more and if anything more happens in Katla volcano.

  1. Right now it looks like the typical Katle grumble. No confirmed depth as of yet, but the drumplot suggests shallow activity due to the pointly spikes on the plotter. I don’t know att all, but my guess is that this is just a very minor upset.

    Conductivity levels in the next few days will tell.

  2. Difficult to know for sure what is going on. This appears to be similar to the activity I did see in 2011, 2014 when small eruptions took place in Katla volcano. Then it took few days from the start of the earthquake swarm activity until an eruption happened. If that is going to happen now I don’t know.
