(LA Times) – A magnitude 3.3 earthquake was felt in parts of Southern California on Sunday afternoon, one in a series of quakes to hit the Riverside County area. The latest quake occurred about 4:36 p.m. and was centered on Glen Avon, south of Fontana. According to the U.S. Geological Survey, it was felt across swaths of the Inland Empire, a region that has had hundreds of small quakes over the weekend, including one that
registered a magnitude 3.1. On Friday, seismologist Lucy Jones wrote on Twitter that small earthquakes can be felt if they’re shallow — only 1 mile underground instead of 5 miles or more. She called the area a “perennial hotspot” of small, clustered quakes and nothing out of the ordinary for California. “This is just a place where the earth sputters along instead of letting go all at once,” she said.
