An earthquake of magnitude 3.0 occurred only 8 minutes ago 20 miles southeast of Redding, California, United States, the United States Geological Survey reported.
The quake hit at a very shallow depth of 1.6 miles beneath the epicenter near Redding, Shasta County, California, USA, late at night on Wednesday 31 March 2021 at 11:03 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 European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.0 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Shingletown (pop. 2,300) located 8 miles from the epicenter, Anderson (pop. 10,200) 13 miles away, Cottonwood (pop. 3,300) 14 miles away, and Bella Vista (pop. 2,800) 15 miles away. In Redding (pop. 91,600, 20 miles away), Shasta Lake (pop. 10,200, 22 miles away), Lake Shasta (pop. 10,200, 22 miles away), and Red Bluff (pop. 14,100, 22 miles away), the quake was probably not felt.
