Earthquake swarm north of Grindavík town

Around 14:00 UTC an earthquake swarm started north of Grindavík town. This look like a tension breaking earthquake swarm and that suggests an inflation is happening again in Fagradalsfjall volcano (mountain). Largest earthquake so far had a magnitude of Mw3,3 and second largest earthquake so far had a magnitude of Mw3,0.

This earthquake swarm is ongoing, but like with all earthquakes swarms in this area it shows a sign of slowing down for few hours before continuing. There is a chance this earthquake swarm might be over. But I am not yet sure if that is the case.


Since I am broke in April. Please remember to support my work with donations if you can. Thanks for the support. 🙂

Quiet time in Iceland

The year 2022 has not seen a lot of activity in Iceland so far. If that is going to change I don’t know. Since I mostly just report on current activity and not historical activity, when it comes to historical activity I do maintain a list of major earthquakes in Iceland.

While it is quiet I normally won’t post a lot here. That results in smaller traffic. As the world goes. I have made the decision to keep PayPal. This allows people to donate to me and my work here when things are quiet and help me with everything.

The quiet time can end at any time in Iceland, but it can be quiet for up to 10 months at the longest. How long current quiet period is going to last is anyone guess.
