A major earthquake shook the Los Angeles area in the middle of the morning rush hour on Thursday.

The United States Geological Survey has given a preliminary measurement of 4.7 for the earthquake, but the measure remains fluid. The USGS says the quake originated more than 4 miles north of Malibu.

An aftershock of roughly 2.8 magnitude also shook the Los Angeles area shortly after the original quake.

There have been no immediate reports of injuries or deaths due to the quake.
