LOS ANGELES -- More than 100 aftershocks have rattled Orange County south of Los Angeles where a magnitude-5.1 earthquake struck Friday.
The U.S. Geological Survey says the latest -- a magnitude-3.4 -- hit Saturday morning a mile from La Habra, about 20 miles south of Los Angeles.
Police in the nearby city of Fullerton say 20 apartment units and half a dozen homes were red-tagged, displacing 83 people.
Friday night's quake caused a rock slide, water main breaks and items to fall off shelves.
Despite the relatively minor damage, no injuries have been reported.
The quake, initially measured at 5.3 magnitude then raised to 5.4 before being revised downward, hit at 9:09 p.m. (12:09 a.m. ET), the U.S. Geological Survey reported. It was centered between the cities of La Habra and Brea in Orange County, about 20 miles southeast of downtown Los Angeles.
The police in Brea reported that a rockslide closed a canyon road. The slide forced a car to overturn and one person suffered minor injuries, NBC Los Angeles quoted police as saying.
Fire officials reported several small water main breaks and gas leaks in La Habra, Fullerton and La Mirada, NBC Los Angeles reported.
"Just about everything in the city that could go wrong is going wrong," a La Habra Police Department spokesperson told NBC Los Angeles by phone.
The quake was preceded about an hour earlier by a magnitude-3.6 quake and was followed by a swarm of small quakes that also reached magnitude-3.6 in about the same area, according to the USGS website.

Vin Scully was announcing Friday night’s Dodgers exhibition game against the Angels at Dodger Stadium when the quake hit. Scully didn't breaking stride with his commentary as cameras shook. He then waxed on about the 1989 Loma Prieta earthquake that shook the World Series at San Francisco's Candlestick Park.
Los Angeles Mayor Eric Garcetti said in a news release that no damage had been found by police or firefighters within that city.
But residents in Fullerton reported feeling the quake and told NBC Los Angeles that glass and mirrors fell and broke in their homes.
Metro Los Angeles tweeted that trains would slow for inspections of tracks and equipment and riders should expect delays.

The USGS said the quake was shallow, just 4.6 miles deep. More than 30 aftershocks were reported.
