A magnitude 4.4 earthquake struck just outside of Los Angeles on Monday, rattling early morning commuters across a wide swath of Southern California but causing no damage or injury.

The quake, which was initially registered by the U.S. Geological Survey as a 4.7, struck shortly before 6:30 a.m. local time and was centered about 6 miles north-northwest of Westwood, California.

The shaking was felt as far away as Orange County to the south and Palmdale to the east, but authorities said they had received no reports of damage or injury and no water main breaks or power outages. In Santa Monica, the quake was felt as a sharp jolt which awakened many, even most residents.

Some commuter trains were halted while crews inspected the tracks for damage.
