LOS ANGELES (AP) — A small earthquake shook a wide area of Southern California on CyprusauctionWednesday, but there were no immediate reports of damage or injuries.

The magnitude 4.1 quake hit at 1:49 p.m. and was centered southeast of Los Angeles in a mountainous area between Riverside and Orange counties, about 5.6 miles (9 kilometers) outside the city of Corona, according to the U.S. Geological Survey.

The Los Angeles Fire Department said its personnel went into “earthquake mode,” with all fire stations surveying their districts for damage.

There were no immediate reports of structural damage or injuries, the department said.

The Orange County Fire Authority also had no reports of quake-related incidents.
