An earthquake of magnitude 5.4 occurred only 12 minutes ago, the German Research Centre for Geosciences in Potsdam (GFZ) reported. The quake hit at a shallow depth of 10 km (6.2 miles) beneath the epicenter around noon on 20 October at 1.43 pm local time. The magnitude, exact epicenter location and depth could be revised within the next few minutes as the agency updates and refines its calculations, or as other agencies issue their report.
Our monitoring service at VolcanoDiscovery also identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 5.1.
Based on the preliminary seismic data, the quake should have been widely felt by almost everyone in the area of the epicenter. It might have caused light to moderate damage.
Towns and cities near the epicenter that are likely to be affected include Hafnarfjörður (pop. 26,800) in 13 km (8 miles) distance with moderate ground shaking expected, Garðabær (pop. 11,400) in 16 km (10 miles) distance, moderate ground shaking expected, Kópavogur (pop. 31,700) in 18 km (11 miles) distance, moderate ground shaking expected, Reykjavík (pop. 118,900) in 21 km (13 miles) distance, moderate ground shaking expected.

Update Tue, 20 Oct 2020, 14:06The quake occurred in the area of Krísuvík volcano, a system of eruptive fissures, basaltic crater rows and small shield volcanoes on the central Reykjanes Peninsula, which is part of the active tectonic spreading zone of SW Iceland.
The area is also volcanically very active. Several eruptions from this area are documented to have occurred between the 11th and 14th century AD. In recent months, seismic activity along the Reykjanes peninsula has been elevated and has been found to be related to magma intrusion in the rift zone.
Today's quake has been the largest in the area so far during the current year. Whether it is caused by tectonic movements or magma movements, or both, and whether it could be a precursor to new volcanic activity is not known at the moment, but cannot be ruled out.
Update Tue, 20 Oct 2020, 14:10A large part of Iceland's population could have felt the earthquake. During the first 15 minutes, we received more than 100 user reports of people who felt it. Mild shaking was perceived in the capital Reykjavik. There are no reports of damages.
Update Tue, 20 Oct 2020, 17:03The Icelandic Met Office (IMO) posted an update on the mag 5.6 quake which occurred at 13:43 in Núplahlíðarháls, about 5 km vest of Seltún, mentioning that seismic activity remains high in the area. By now over 100 aftershocks have been recorded.
