Significant magnitude 5.0 earthquake 73 miles southeast of Akutan, Alaska5.0 quake 55 mi SE of Akutan 4 Nov 3.23 am (GMT -9)
Just 21 minutes ago, a 5.0-magnitude earthquake struck near the town of Akutan, Alaska. The tremor was recorded early morning on Wednesday 4 November 2020 at 3.23 am local time, at a moderately shallow depth of 27 miles below the surface.
The event was filed by the United States Geological Survey (USGS), the first seismological agency to report it.
Our monitoring service at VolcanoDiscovery identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 5.0 as well.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
