3.1 quake 11 Apr 2:45 am (GMT -7)
A very shallow magnitude 3.1 earthquake was reported early morning near Ridgecrest, Kern County, California, USA.
According to the United States Geological Survey, the quake hit on Sunday 11 April 2021 at 2:45 am local time at a very shallow depth of 3.7 miles. 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 European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.1 as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Searles Valley (pop. 1,700) located 11 miles from the epicenter, Ridgecrest (pop. 28,800) 12 miles away, China Lake Acres (pop. 1,900) 14 miles away, and Inyokern (pop. 1,100) 15 miles away.
