Strong earthquake swarm north of Kolbeinsey Island

There seems to be a rather large earthquake swarm taking place north of Kolbeinsey Island. This earthquake swarm started earlier today (24. March 2011). But do to how far it is away from the SIL monitoring network it is hard to know for sure how strong this earthquake swarm actually is. It is also clear from the data that only the largest earthquakes in this swarm are appearing on the Icelandic Met Office web page.

This earthquake swarm might be part of Kolbeiney Island ridge or part of the SPAR fracture zone that is north of Kolbeinsey Island ridge. It is hard to know for sure due to how poorly this earthquake swarm is being recorded by the SIL network. The largest earthquake so far is a ML3.6 at 9.0 km depth (automatic data, not reviewed). But the SIL network can detect earthquakes in this there down to the size ML2.5, but nothing less then that it appears.

    I’ve been missing all the action.
    Since the quakes at Rejkjanes I was going to venture a “forecast”, but these quakes always seem to come in waves, as it really appears to be the case now with both Krisuvik and Kolbeinsey swarms.
