There have been few smaller earthquakes in this area since the largest earthquake, but other than that it has been quiet. This earthquake is believed to have happened because of stress changes on the Reykjanes peninsula because of the eruption in Fagradalsfjall mountain.

  1. Looking at the area just a few short km to the NE of the eruption, there has been a swarm of quakes here for many days. Is this the north end of the dyke?

    Maybe this will be the new eruption site at some point in time. Who knows, but this region is now active, so anything could happen.
