Series of Small Quakes Shake Southern California

A series of small earthquakes, including a preliminary 4.3- to 4.4-magnitude quake near Muscoy in San Bernardino County, struck Southern California on Thursday morning around 9:30 a.m. The strongest quake was widely felt from Los Angeles to San Diego, as well as north to Bakersfield and south to Santa Ysabel. Several aftershocks, including a 3.1-magnitude tremor, followed minutes later. No injuries or significant damage have been reported. Seismologists identified the quakes along the 'Fontana trend,' a zone known for clustered seismic activity, and urged continued preparedness for future earthquakes. Emergency services are monitoring the situation as aftershocks remain possible.
