An earthquake with a preliminary magnitude of 4.2 followed by a strong aftershock rattled Southern California early Wednesday morning, awaking thousands of people.

There were no reports of damage or injuries.

The quake struck at 2:00 a.m. and was centered offshore, 16 kilometers south of Malibu Beach and due west of Los Angeles, at a depth of 14 kilometers, according to the U.S. Geological Survey.

The quake was followed by a 3.5 magnitude aftershock at 2:03 a.m. and progressively weaker aftershocks at 2:22 a.m. and 2:38 a.m.

The temblor prompted the Los Angeles Fire Department to go into Earthquake Mode, which involved a strategic survey of all major “areas of concern,” LAFD said.

“Your LAFD completed a strategic 470 square-mile survey of the City of Los Angeles following the 4.2M earthquake near Malibu. No damage or injuries were reported and normal operational mode has resumed,” LAFD announced at 2:45 a.m.

No tsunami warning was issued by the National Oceanic and Atmospheric Administration (NOAA)
