6.2 quake 20 Dec 12:10 pm (GMT -8)
6.2 quake 20 Dec 12:10 pm (GMT -8)
United States was shaken near Eureka, Humboldt County, California, by an earthquake of magnitude 6.2 only 11 minutes ago, the United States Geological Survey reported.
The quake hit at a very shallow depth of 5.8 miles beneath the epicenter near Eureka, Humboldt County, California, USA, around noon on Monday, December 20th, 2021, at 12:10 pm local time. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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.
Our monitoring service identified a second report from the German Research Centre for Geosciences (GFZ) which listed the quake at magnitude 5.7. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 6.1.
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.
Moderate shaking probably occurred in Ferndale (pop. 1,400) located 31 miles from the epicenter, Rio Dell (pop. 3,400) 36 miles away, and Fortuna (pop. 12,000) 36 miles away.
In Humboldt Hill (pop. 3,400) located 41 miles from the epicenter, Eureka (pop. 27,000) 45 miles away, Bayside (pop. 17,100) 51 miles away, Uniontown (pop. 17,800) 51 miles away, and McKinleyville (pop. 15,200) 55 miles away, the quake should have been felt as light shaking.
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.
