The earthquake swarm that started two days ago (wrote about it here) in Tjörnes Fracture Zone continues and appears to be growing in the past few hours. So far the largest earthquakes have not been stronger then magnitude 2.6 or 2.7 (automatic and reviewed results).

None of this earthquakes have been felt that I know. Since they are good distance (~20 km) from populated areas and are small at the moment. That might change if larger earthquakes start to happen in Tjörnes Fracture Zone. Currently this earthquake swarm activity is mostly continuous with just few stops in it, no stop has so far not lasted more than 1 to 3 hours so far. Currently this earthquake swarm activity is ongoing and I do not expect it to stop at the moment.
