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.

Los Angeles Mayor Karen Bass said fire authorities are surveying the city. There were no immediate reports of injuries.

The quake originated about 7 miles below the surface, and the jolt was felt as far as 45 miles away, the USGS said.

Seismologist Dr. Lucy Jones told Fox LA the quake had a 40% chance of associating with the fault line in Malibu, which runs along the coast.
