15 000 earthquakes hit the Reykjanes Peninsula since February 24, Iceland

The Icelandic Met Office (IMO) has detected around 15 000 earthquakes in Reykjanes Peninsula since an intense earthquake swarm started on February 24, 2021.

By March 1, the number rose to over 10 000 and by March 3 it’s already around 15 000, with quite a few over M4.0 and two over M5.0.

Most of the activity is confined to the vicinity of Keilir and Trölladyngja, IMO said.

The Scientific Council for Civil Protection met at a teleconference on March 1. The meeting was attended by representatives from the Icelandic Meteorological Office, the University of Iceland, the Environment Agency, Isavia-ANS, HS-Orka, and ÍSOR.

The council reviewed satellite images (InSAR) and concluded that the most likely explanation is that magma is forming under the area where the greatest seismic activity has taken place in recent days.
