A shallow, moderate earthquake rocked California's Ventura County coast on Thursday, the US Geological survey said, swaying buildings across a wide area including the city of Los Angeles.
There were no immediate reports of damage or injuries following the magnitude-5.3 quake, which struck at 12:34 pm (1934 GMT), 23 miles east-southeast of Santa Rosa Island at a depth of 10.4 miles (16.8 kilometers).
The Los Angeles Fire Department went into "earthquake mode," pulling crews out of more than 100 stations across the 470- square mile (750-square kilometer) region to sweep neighborhoods for damage to key infrastructure, such as roadways and bridges.
Los Angeles police were also making checks of infrastructure and "critical locations," they said.
