Earthquake swarm in Brennisteinsfjöll volcano

I am sorry that I am late on writing this article. I was moving from Denmark to Iceland and that was a lot of effort and I’ve been tired after this move.

On Sunday, 24 September 2023 an earthquake swarm took place in Brennisteinfjöll volcano, in a area called Geitarfell (Goat Mountain) in Brennisteinsfjöll volcano. Largest earthquakes had a magnitude of Mw3,0 to Mw3,2. A lot of smaller earthquakes took place at this same location.

Yellow dots at the location where the Sunday earthquake swarm took place. There's a lot of earthquake activity on the Reykjanes peninsula at the moment. Shown with two green stars, one at Svartsengi and the other in Kleifarvatn lake.

This earthquake activity didn’t have any short term signs that an eruption is about to happen at this location. I don’t know when last eruption took in this location, but it was clearly more than 6000 years ago.

Earthquake webicoders

Since I have moved back to Iceland. I am now recording earthquakes again. The webicoders are going to go online tomorrow (if no delays). They can be found here once they are back online.
