Yesterday (29-January-2015) there was a minor earthquake swarm in small mountain named Helgafell on the Reykjanes peninsula. Largest earthquake in this swarm had the magnitude of 3,2 and was felt in Hafnarfjöður, a town closest to the source of this activity.

There is a chance of more earthquake activity in this area for next few days to weeks. Earthquake swarm activity is common on the Reykjanes peninsula.
Thank you Univ. of Iceland, IMO, and Dept. of Civil Protection for a thorough, very informative update.
Jon, is there anything other than rifting on Reykjanes?
