Today (19-October-2013) new earthquake swarm started on the Reykjanes ridge. So far this earthquake swarm has been small, with only 16 earthquakes recorded. Largest earthquake in this swarm had magnitude 3,3 at the depth of 6,1 km.

I am expecting more earthquake activity in this area of the Reykjanes ridge over the next few days and weeks. It is impossible to know when an new earthquakes swarm starts. The best way is to monitor current activity at Icelandic Metorlogical Office website and on my webicorder website.
