3.5 magnitude earthquake strikes Malibu hours after previous temblor

MALIBU, Calif. (KABC) -- The Malibu area was rattled by a second earthquake within a roughly seven-hour period Saturday as the area recovered from this week's rainstorms and officials watched carefully for signs of possible debris flows.

"Minor magnitude 3.7 and 3.5 earthquakes struck at 11:44 p.m. on 2/14 and 6:30 a.m. on 2/15 in Malibu, according to the US Geological Survey," the city posted Saturday on X. "The earthquakes did not cause further mud/rockslides or debris flows in the burn areas."

The 3.7-magnitude quake was centered about 8 miles northwest of Malibu, according to the USGS. The 6:30 a.m. quake was located 7 miles northwest of Malibu.

No injuries or major damage were reported.

Local authorities had been monitoring the area overnight, focusing on Malibu, parts of Ventura County, West Los Angeles, the San Fernando Valley, the South Bay, Long Beach and other parts of Los Angeles -- covering a roughly 30 mile section of the Southland.

"Rest assured that our deputies are conducting critical facilities checks throughout the region to ensure the safety of our communities," the Los Angeles County Sheriff's Department's Lost Hills station noted on social media Saturday following the late Friday quake. "We have not received any reports of any injuries or structural damage at this time but will continue to monitor the situation."

The initial quake was felt in parts of Los Angeles and Ventura counties including Agoura Hills, Thousand Oaks, Camarillo, the San Fernando Valley, the South Bay, Long Beach and other parts of Los Angeles.

The Malibu area experienced some mud and debris flow from heavy rainfall Wednesday through Friday while continuing to recover from January's wildfires.
