5.0 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. Weak shaking might have been felt in Akutan (pop. 1000) located 55 miles from the epicenter, Unalaska (pop. 4,500) 73 miles away, and Dutch Harbor (pop. 4,400) 74 miles away.
This story will be updated soon by VolcanoDiscovery. If you’re in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
