LOS ANGELES (CNS) - A magnitude-4.2 earthquake struck near Malibu early Wednesday morning, prompting Los Angeles emergency management officials to conduct 470-square-mile survey of the city.
The quake struck at 2 a.m., followed by a magnitude-3.5 aftershock at 2:03 a.m., according to the U.S. Geological Survey. Two more aftershocks were reported. The first was 2.8-magnitude at 2:22 a.m. and the second was 2.6- magnitude at 2:38 a.m.
The quakes were centered offshore, about 10 miles south of Malibu and 15 miles southwest of Santa Monica, according to the USGS.
The 4.2-magnitude quake was about 9 miles deep. It was centered 15.4 miles west of Venice and 16.3 miles west of El Segundo.
There were no immediate reports of injuries or damage, and the National Weather Service said no tsunamis were expected.
"All 106 neighborhood fire stations will conduct a strategic survey of their districts, examining all major areas of concern (transportation infrastructures, large places of assemblages, apartment buildings, power-lines, etc)," Los Angeles Fire Department Nicholas Prange said.
He added that the LAFD was now in "earthquake mode" and the survey would last for approximately one hour.
Shortly before 9 a.m., the department announced that the survey was complete.
"No damage or injuries were reported and normal operational mode has resumed," the LAFD tweeted.
The examination was conducted from the ground, air and sea.
