3.7 quake 19 Apr 7:39 pm (GMT -7)
A magnitude 3.7 earthquake near Chico, Butte County, California, USA, was reported only 9 minutes ago by the United States Geological Survey, considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at a shallow depth of 13 miles beneath the epicenter early evening on Monday 19 April 2021 at 7:39 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 3.7 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Princeton (pop. 300) located 8 miles from the epicenter, Willows (pop. 6,100) 9 miles away, Durham (pop. 5,500) 15 miles away, Chico (pop. 90,300) 18 miles away, Orland (pop. 7,600) 19 miles away, Gridley (pop. 6,600) 21 miles away, Paradise (pop. 26,500) 27 miles away, and Yuba City (pop. 66,900) 34 miles away.
