Earthquake swarm in Tjörnes Fracture Zone

Today (18 October, 2011) at 08:53 UTC a earthquake swarm started in TFZ. So far this earthquake swarm is small in nature, only about dozen earthquakes so far. But the largest earthquakes have been with the size of ML3.6 according to IMO automatic earthquake detection system (called SIL). There is a good chance that this earthquake swarm is going to continue for the next few hours. But it is hard to know that for sure at the moment.
