5.1 quake 24 Jan 12:16 pm (GMT -9)
United States was shaken near King Cove, Aleutians East County, Alaska, by an earthquake of magnitude 5.1 only 26 minutes ago, the United States Geological Survey (USGS) reported.
The quake hit at a moderately shallow depth of 22 miles beneath the epicenter near King Cove, Aleutians East County, Alaska, USA, around noon on Sunday 24 January 2021 at 12:16 pm local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the German Research Centre for Geosciences (GFZ), which listed it as a magnitude 5.5 earthquake. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 5.5.
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 44 miles from the epicenter, Cold Bay (pop. 120) 58 miles away, and False Pass (pop. 40) 60 miles away.
