Strongest Earthquake in North Iceland in 34 Years

North Iceland is being subject to a series of ongoing earthquakes which began on Saturday. The strongest quake in the series, which hit around 2 am on October 21, had a magnitude of 5.6. It is the strongest to have occurred in the Tjörnes fissure zone since 1976 when a 6.2 quake hit near Kópasker.

The region’s inhabitants clearly felt the seismic activity over the weekend, particularly in Siglufjörður where objects fell from shelves and cracks appeared in windows. A resident described the impact as if a truck had rammed his house, RÚV reports.

People felt the earthquakes all over North Iceland but also as far as Ísafjörður in the West Fjords, Seyðisfjörður in the East Fjords and the capital region in the southwest.

The activity is ongoing with hundreds of earthquakes having been picked up by sensors in North Iceland since Saturday. The activity peaked in the night before Sunday but slowed down in the morning. Then it picked up again in the evening and last night.

At least nine rather sharp earthquakes have hit the region since midnight, the largest of which had a magnitude of 4.1. The others ranged from 3.0 to 3.8, ruv.is reports.

The Icelandic Meteorological Office warns that more aftershocks might be coming up and that the strongest of these might exceed 4.0.
