Small 2.9 quake hits near Fontana, San Bernardino County, California, USA

A magnitude 2.9 earthquake near Fontana, San Bernardino County, California, USA, was reported only 16 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 very shallow depth of 4.8 miles beneath the epicenter in the afternoon on Sunday, January 18th, 2026, at 5:41 pm local time.
