An earthquake rattled Southern California on Thursday, July 31. The U.S. Geological Survey reported the quake occurred at 9:32 am PT and was pinpointed nearly 4 miles west of Muscoy, CA, about 50 miles east of LA. It struck at a depth of just over 3 miles.
This is just one of four earthquakes that hit the area Thursday morning, as three other quakes, ranging between 2.8 and 3.1 magnitude, also shook the Rialto area.
Multiple reports say all four earthquakes were felt across the Los Angeles metropolitan area.
The earthquakes occurred less than 24 hours after California received a tsunami advisory. After a powerful 8.8-magnitude earthquake hit Eastern Russia on Tuesday afternoon, a tsunami advisory was issued for the entire West Coast. A tsunami warning went into effect for about a 40-mile stretch of Northern California’s coast, Santa Barbara and San Luis Obispo counties.
According to the LA Times, Humboldt and Del Norte counties experienced the highest waves, with heights reaching 2.5 feet in San Francisco and generally staying under 1 foot in SoCal. Wave measurements included 1.2 ft at Humboldt Bay, 0.8 ft at Point Reyes, 1.1 ft at Monterey, 1.3 ft at Port San Luis, 0.4 ft at Richmond, and 0.5 ft at Santa Monica.
