On 7-December-2015 a minor earthquake swarm took place in Krafla volcano. The strongest earthquake in this swarm had the magnitude of 3,2. I don’t know if it was felt in nearby town. It was followed by few minor earthquakes, both before and after.

I don’t expect any more earthquake activity in Krafla volcano. At least not outside normal background activity.
