A moderate earthquake jolted residents throughout the greater Los Angeles area Saturday.

There were no reports of serious injuries or damage.The magnitude-3.8 quake struck two miles southeast of Alhambra at 6:32 p.m., said seismologist Lucy Jones of the U.S. Geological Survey. It was a new earthquake and not an aftershock, she said.

A magnitude-1.8 quake that hit the same area at about 2:30 p.m. was determined to be a foreshock of the larger temblor, Jones said.

The quake was felt in western and downtown portions of Los Angeles, as well as Burbank and Pasadena. The shaker was felt as far south as La Habra, 15 miles southeast of the epicenter, and as far east as Baldwin Park, about sevenmiles east of the epicenter.

Numerous car alarms went off in Alhambra, 15 miles east of downtown Los Angeles, police said.

"It was a good one. It started off like a little rumble, and hit real quick," Los Angeles County Sheriff's Department Deputy Mark Bailey said. "Then it was over. No pictures fell or anything like that."

Matthew Gladheart, 22, of Monrovia, said a ceiling fan fell on his leg.

"It felt like a truck hit the apartment building and then it kind of rolled a little bit when it was over," Gladheart said.
