LOS ANGELES -- An earthquake east of downtown Los Angeles rippled across Southern California before dawn Tuesday, jolting millions of people awake and putting first-responders on alert.
The magnitude-4.4 quake, centered about 10 miles from City Hall, struck shortly after 4 a.m., according to the U.S. Geological Survey.
There are no reports of damage, injuries or power outages linked to the temblor.
"All is calm in the city of Los Angeles," Los Angeles Fire Department Capt. Steve Ruda said.
Nearly an hour after the quake, the California Highway Patrol got reports of a buckled 10-foot stretch of concrete in a center lane of southbound Interstate 5 south of downtown in the Downey area.
CHP Officer Daniel Asleson said later that the quake probably didn't cause the buckling. Damage was reported a day earlier in the lane, which is heavily used by tractor-trailers.
California Department of Transportation crews temporarily patched the area again early Tuesday, and the lane reopened an hour later. Work on a permanent fix begins Tuesday night.
"The earthquake probably did contribute to it, a little bit, but . . . it's normal wear and tear," Officer Asleson said.
"It was a shake, but not bad. Our inmates slept through it, and we had a few calls, but not as many as you would think," Pico Rivera sheriff's station Sgt. Jacqueline Sanchez said.
Deputies were dispatched immediately to make "critical facility checks -- bridges and dams, stuff like that," the sergeant said.
