Earthquake Rattles SoCal Wednesday Night: Did You Feel It?

SAN BERNARDINO, CA— A magnitude 4.2 earthquake struck with an epicenter just west of San Bernardino, near Rancho Cucamonga on Wednesday evening, according to the United States Geological Survey.

The temblor was reported just after 7:45 p.m.

The quake rattled residents of San Bernardino County, Los Angeles County, Riverside County, and San Diego County. It was felt from the Pass Area to Riverside County, as far south as Oceanside, according to initial reports.

"Location is pretty deep (15 km) very close to the San Jacinto fault," Southland seismologist Lucy Jones wrote on X. "That part of the fault is generally locked - it had a M7 in the 19th century. We often see small quakes like this below locked segments."

This is the second magnitude 4.2 earthquake to strike in the San Bernardino area in 20 days. The first struck near Lytle Creek, a small remote community about 16 miles northwest of downtown San Bernardino, Jan. 5.

"The two quakes are probably on the same fault, but they are far enough apart in both time and space to not have an obvious correlation," Jones tweeted.

No injuries were reported as a result of today's quake.

This is a developing report and additional information will be added as it is received.
