Magnitude 5.4 earthquake strikes near King Cove, Aleutians East, Alaska, USA

5.4 quake 3 Feb 12:53 pm (GMT -11)
5.4 quake 3 Feb 12:53 pm (GMT -11)
Just 19 minutes ago, a 5.4-magnitude earthquake struck near King Cove, Aleutians East, Alaska, USA. The tremor was recorded around noon on Thursday, February 3rd, 2022, at 12:53 pm local time, at a moderately shallow depth of 22 miles below the surface.
The event was filed by the United States Geological Survey, the first seismological agency to report it.
A second report was later issued by France's Réseau National de Surveillance Sismique (RéNaSS), which listed it as a magnitude 5.3 earthquake. Other agencies reporting the same quake include the German Research Centre for Geosciences (GFZ) at magnitude 5.5, and the European-Mediterranean Seismological Centre (EMSC) at magnitude 5.4.
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 King Cove (pop. 1000) located 61 miles from the epicenter, Cold Bay (pop. 120) 77 miles away, and False Pass (pop. 40) 82 miles away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. 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.

Port Heiden, AK / Very weak shaking (MMI II) : Heard and felt a sort of deep rumbling buzzing and felt slight movement for less than a minute, and got a little bit of sensitive vertigo sensation, making me feel way more tired unstable while sitting down than I already was feeling at the time.
