LOS ANGELES (Reuters) - A small earthquake hit the northern Los Angeles area just before 1 a.m. (4 a.m. EDT) on Thursday, waking residents across a broad swathe of the area, but there were no immediate reports of significant damage.
The 4.5 preliminary magnitude quake was centered 4.1 miles north-northwest of the suburb of Chatsworth, according to the U.S. Geological Survey. It was extremely shallow, at only 3 miles deep.
Chatsworth, the unofficial capital of the porn movie industry, is about 32 miles northwest of downtown Los Angeles.
Residents reported a strong jolt, followed by a lot of shaking. Some said pictures fell off walls, water sloshed around in toilets, and television sets wobbled on cabinets. A police spokesman said the quake triggered hundreds of alarms.
It was followed by two aftershocks, both with a preliminary 1.6 magnitude.
Chatsworth is just six miles west of Northridge, the epicenter of the magnitude 6.7 quake that killed 57 people and injured more than 9,000 in 1994.
