4.5-magnitude quake rattles Southern California

A moderate earthquake rattled the Los Angeles area early Thursday. The magnitude 4.5 temblor struck just before 1 a.m. about 4 miles northwest of Chatsworth, according to a preliminary report from the U.S. Geological Survey.

There were no immediate reports of injuries or significant damage, said spokesman Brian Humphrey, of the Los Angeles Fire Department. The quick jolt was felt by residents across Los Angeles County, and many reported that their houses vibrated, windows rattled and books, pictures and other items fell.

Chatsworth is about 30 miles northwest of downtown Los Angeles.
