An earthquake measuring 4.2 shook a large part of the Los Angeles region on Friday. There were no immediate reports of damage or injuries, authorities said.

The quake struck at 10:55 a.m. PT in the San Gabriel Mountains east of L.A., according to the U.S. Geological Survey.

The temblor was centered near the remote Lytle Creek community in San Bernardino County. The population in Lytle Creek was just 725, in the 2020 Census. The community is located north of the city of Rancho Cucamonga, about 60 miles from downtown L.A.

Seismologist Dr. Lucy Jones posted on X, formerly Twitter, that Lytle Creek is situated in an area “where the San Andreas and San Jacinto faults come together.” Jones said in 1970, there was a magnitude 5.2 earthquake near the same location.

About an hour after the quake hit, the San Bernardino County Fire Department wrote on X that it had not received any calls for service related to the temblor.

The earthquake was felt across the region, with social media users in Los Angeles, Burbank, Long Beach, Anaheim and other areas saying on X  they felt the shaking.

“There have been NO reports of injury, structure or infrastructure damage within our city of L.A. jurisdiction,” the Los Angeles Fire Department added on X.
