Earthquake swarm in Tjörnes Fracture Zone east of Grímsey island

Today (09-June-2017) there has been a earthquake swarm in Tjörnes Fracture Zone east of Grimsey island. This was fairly large earthquake swarm in number of earthquakes that happened. Largest magnitude that happened was 2,2 and second largest was 2,1. All other earthquakes where smaller and I think around 40 earthquakes happened in this earthquake swarm.

It seems that this earthquake swarm is over, at least for now. This area of Tjörnes Fracture Zone has been showing increasing earthquake activity over the last few weeks. It is difficult to know if that keeps up as it has been doing.

The earthquake swarm off Flatey island is now entering its fifth or six week. There are no signs of that earthquake activity quieting down for now at least.
