IMO's SIL-Seismic Network located automatically around 1500 earthquakes this week, that is considerably more than the week before when they were around 830. One thousand earthquakes have been manually reviewed, but the five hundred that have not yet been reviewed are minor earthquakes that are a part of seismic swarms offshore N-Iceland. The biggest difference between weeks was that the seismic activity offshore N-Iceland increased considerably 15th to 17th of September. Then the focus of the seismic activity shifted over to the eastern part of the Húsavík-Flatey Fault. The largest earthquakes of the week were located there on 15th of September and were M4.6 and M4.0. These earthquakes were felt widely around N-Iceland. Two more earthquakes above M3.0 were measured this week. Around noon on 14th of September an M3.4 earthquake occurred offshore N-Iceland and on 15th of September M3.1 earthquake occurred near the Skaftá cauldrons in western Vatnajökull Ice-Cap. Eight earthquakes were measured in and around Grímsvötn volcano and two in Hekla volcano. More
