Earthquake in Askja volcano

A magnitude Mw3,5 earthquake took place in Askja volcano today (9-November 2025) at 09:39 UTC. This was a single earthquake with no aftershocks. It is unlikley that more earthquakes are going to happen following this earthquake.

There has been some inflation in Askja volcano in recent years. It is my view that that inflation is not going to result in a eruption for the next few decades. That might change if the situation changes in Askja volcano. At the current time, that seems unlikely to happen.

Trace of the Mw8,2 earthquake in Alaska, United States

I don’t have anything to say about the earthquake that took place (on 29-July-2021 at 06:15 UTC) in Alaska, United States since I don’t know the area geology features. I am going to show the trace of this earthquake as it did appear on my geophone in Iceland.

The earthquake trace on north-south directed sensor that I have. It shows the P wave, the small S wave and the surface waves that I did record in Iceland.
