A series of minor earthquakes, the largest with a magnitude of 3.7, hit 27-33 kilometers east-southeast of Grímsey, Iceland’s northernmost inhabited island, shortly after 7:45 pm yesterday. Most of the other quakes were around a magnitude of two.

Einar Kjartansson, geophysicist at the Icelandic Meteorological Office, told Morgunblaðið that earthquakes of this magnitude hit the region around Grímsey at one to two month intervals.
The earthquake swarm was not out of the ordinary and even though islanders may have felt the strongest earthquake, they were hardly alarmed, Einar said—people are used to the ground trembling in Grímsey.
