LOS ANGELES -- A pre-dawn earthquake rolled across the Los Angeles basin on Monday, rattling residents from the San Fernando Valley to Long Beach.
The quake's magnitude was 4.4 and it was centered 15 miles west-northwest of the downtown civic center, according to the U.S. Geological Survey.
Los Angeles police and fire officials said there were no immediate reports of damage.
"It felt like a bomb going off underneath our house," said George McQuade, a West Hills resident. "Nothing was damaged, but it sure woke everyone up. It was an eye-opener."
Tri-State Olympic medalist Nick Goepper is visiting Los Angeles and left a message on Twitter at about 9:50 a.m.
The 6:25 a.m. quake occurred at a depth of about 5 miles.
The epicenter was 6 miles from Beverly Hills, 7 miles from Universal City and 7 miles from Santa Monica, the USGS said.
