A powerful earthquake swarm is brewing in Öxarfjörður fjord in North Iceland. Close to 300 earthquakes have been detected so far today by the Icelandic Met Office (IMO). The largest event was a magnitude 3.3 quake that hit at 4.01 this morning and two M3 earthquakes hit at 3.26 and 4.03.
The earthquakes are in Iceland's northern rift zone, the socalled Tjörnes peninsula rift zone, one of the transform regions between the North America and Eurasia tectonic plates that crosses the island.
Tjörnes is a peninsula located at the northeast corner of Iceland, between Öxarfjörður and Skjálfandi fjords. The largest town in the area is Húsavík with a population of 2.200.
The SIL system
Earthquake data on IMO’s web-site are derived from IMO’s automatic SIL monitoring network, which automatically detects and locates earthquakes in Iceland and the surrounding offshore region. The map and the corresponding graph are updated every five minutes.
The network has been in operation for almost two decades. Besides evaluating source function and mechanism information carried from below by micro-earthquakes, it provides near real-time information that is used as the basis for an alert system.
