Location of recent quakes (5 Oct 2012) in the TFZ
A new small swarm of earthquakes started east of Grímsey Island in the Tjörnes Fracture Zone (TFZ) north of Iceland yesterday 4 Oct. So far, there have been 41 quakes during the past 48 hours, mostly of small magnitudes (1-2) at various depths mostly around 10 km. The largest quakes was a magnitude 3.1 event at 11:35 UTC.
There are possibly a few active volcanoes in this area, but whether this swarm (and the recent other swarms) is tectonic in nature (likely) or related to magma movements is unclear.
