Today (31-March-2015) there has been a minor earthquake swarm in Krísuvík volcano. Total number of detected earthquakes was 27 so far.
Largest earthquake in this swarm had the magnitude of 2,6 according to reviewed results from Icelandic Met Office. Other earthquakes where smaller in magnitude. This is just tectonic activity at the moment. There has been inflation and deflation taking place in Krísuvík volcano for past several years and such activity is known to start strong earthquake activity in both deflation and inflation stage. At the moment there is nothing suggesting there is an eruption imminent in Krísuvík volcano.
