LOS ANGELES—A magnitude-4.2 earthquake struck near Malibu early Jan. 25 morning, giving thousands of residents a rude awakening and prompting Los Angeles emergency management officials to conduct a 470-square-mile survey of the city that turned up no signs of damage or injuries.
The quake struck at 2 a.m., followed by a magnitude-3.6 aftershock at 2:03 a.m., according to the U.S. Geological Survey. Two more aftershocks were reported. The first was 2.9 magnitude at 2:22 a.m. and the second was 2.8 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 agency.
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.
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 following the temblor, noting that the agency went into “earthquake mode.”
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 fire department wrote on Twitter.
The examination was conducted from the ground, air, and sea.
Malibu officials said there were no signs of any damage in that city, and all roads remained open. Emergency officials, however, warned motorists to “beware of potential falling rocks on Malibu Canyon, Kanan, and other canyons.”
Ironically, the quake occurred almost exactly five years after a similar-sized quake rattled the Southland at 2:09 a.m. on Jan. 25, 2018.
