An hour ago, the United States Geological Survey (USGS) reported that a 3.1-magnitude earthquake struck 4.34km southeast of Rancho Cucamonga, San Bernardino County, California, USA at a shallow depth of 11.5km. The European-Mediterranean Seismological Centre (EMSC), reported the earthquake at the same magnitude.
The exact magnitude, epicenter, and depth of the quake might revised in the next hours or minutes as seismologists review their data and calculations, or else as other agencies issue their report.
Towns or cities that might have felt a weak shaking include Rancho Cucamonga (pop. 175,200) located 3 miles from the epicenter, Upland (pop. 76,400) 5 miles away, Ontario (pop. 171,200) 6 miles away, Fontana (pop. 207,500) 7 miles away, Eastvale (pop. 59,000) 8 miles away, Rialto (pop. 103,100) 11 miles away, Pomona (pop. 153,300) 11 miles away, and Riverside (pop. 322,400) 13 miles away.
