Abstract — Over 14,000 earthquakes were located in 2001 by the SIL seismic system. During the first half of the year the majority of the located earthquakes were aftershocks of the magnitude 6.6 earthquakes of June 2000. The Mýrdalsjökull region was more seismically active than usual in the first half of the year and the Reykjanes ridge was fairly active in the latter half of the year. Many small earthquake swarms occurred as well, the two largest along the Tjörnes Fracture Zone, offshore northern Iceland. The larger of these swarms originated in Öxarfjörður with a total number of earthquakes greatly exceeding previous swarms in the area, recorded by the SIL system. Five stations were added to the SIL network and one station was dismantled. At the end of the year 42 seismic stations comprised the SIL network.
