3.2 quake 30 Jul 5:59 pm (GMT -7)
The United States Geological Survey reported a magnitude 3.2 quake in the United States near Redlands, San Bernardino County, California, only 7 minutes ago. The earthquake hit in the afternoon on Friday 30 July 2021 at 5:59 pm local time at a shallow depth of 9.3 miles. 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 3.2 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Redlands (pop. 71,000) located 2 miles from the epicenter, Colton (pop. 54,600) 6 miles away, Highland (pop. 54,900) 6 miles away, San Bernardino (pop. 216,100) 7 miles away, Moreno Valley (pop. 204,200) 7 miles away, Rialto (pop. 103,100) 10 miles away, Riverside (pop. 322,400) 12 miles away, and Fontana (pop. 207,500) 13 miles away. In Anaheim (pop. 350,700, 43 miles away), the quake was probably not felt.
