Magnitude-5.1 Earthquake Strikes La Habra

Dozens of aftershocks were reported throughout the night

A magnitude-5.1 earthquake struck La Habra Friday night, about an hour after a magnitude-3.6 quake hit the same area, according to the U.S. Geological Survey.

The quake was first reported just after 9 p.m. as a magnitude-5.3 but it was downgraded within 30 minutes. More than 30 aftershocks were reported through the night.

Residents from across Southern California reported feeling the shaking, including in Kern, Los Angeles, Orange, Riverside, San Bernardino, San Diego and Ventura counties.

The quake was about 5 miles deep. There were no reports of surface rupture and scientists are not yet able to assign it to a particular fault, Caltech seismologist Robert Graves said.

The earthquake was probably 10 times larger than the March 17 magnitude-4.4 quake near Encino in terms of energy released, Caltech's Lucy Jones said.

Fire officials reported several small water main breaks and gas leaks in La Habra, Fullerton and La Mirada. Southern California Edison reported at least 2,000 customers without power following the quake.

"Just about everything in the city that could go wrong is going wrong," the La Habra Police Department told NBC4 via phone as the city dealt with water main breaks, power outages and evacuations.

The American Red Cross opened a shelter for La Habra residents impacted by the quake. The shelter is at the La Habra Community Center at 101 W. La Habra Blvd.

The earthquake also caused a rockslide in Carbon Canyon in Brea, according to the Brea Police Department. The rockslide forced a car to overturn and one person suffered minor injuries, police said. Carbon Canyon Road was still closed as of 7 a.m. Saturday morning.

The Los Angeles police and fire departments conducted an assessment and report no damage in the city, LA Mayor Eric Garcetti said.

Disneyland visitors reported getting stuck on the Matterhorn ride, and rides were shut down for inspections after the quake.

Fullerton resident Daniel Taylor told NBC4 via email everything fell down in his home.

"I felt both quakes. The second quake hit really hard, it was a hard and fast quake," he said. "My 100-gallon fish tank went down. Water damage everywhere from the tank. My water pipes under my sink cracked."

One viewer in Walnut said the power went out for 10 minutes as the quake struck.

"The whole room was shaking," said one NBC4 viewer in Palmdale. "My bed was rolling for longer than most I've felt."

A La Habra resident reported a mirror falling and shattering during the quake, and another viewer called in with a report of broken glass.

There were minor delays on Metro rail lines while crews inspect the tracks and equipment.

Building and Safety officials have identified about 20 apartment units on the 2700 block of Associated Road in Fullerton that have been evacuated due safety concerns. 

Three homes on the 2900 block of Juanita Place in Fullerton also raised a red flag after it suffered major earthquake damage, according to Fullerton Police.Homes on hthe 1800 block of Del Norte were also evacuated.
