112 quakes

The seismic monitoring system of the Icelandic Meteorological Office detected 66 quakes in the mountain on Saturday and more than 50 on Sunday. A total of 116 quakes have been detected since Saturday morning when the swarm began.

The swarm has included several relatively large quakes, measuring more than 3 on the Richter scale. Quakes of this magnitude have not been detected in the mountain since 1992.

A 3.5 magnitude quake was detected at 19:20 on Saturday evening, followed by a second 3.1 magnitude quake at 19:58 and a 3.7 magnitude quake at 21:25. A fourth larger quake, 3.8 on the Richter scale, was then detected at 8:48 on Sunday morning.

The epicenter of the activity has been in the east-northeaster slopes of mount Skjaldbreiður at a depth of of 5-6 km (3.1-3.7 miles.) The activity appears to be subsiding, the IMO reports.
