Authorities are coordinating extensive cleanup efforts following the strongest earthquake to hit the northern part of the U.S. state of California in 25 years.
A 6.0-magnitude quake shook the region early Sunday, injuring more than 100 people, causing major damage to buildings, igniting fires and knocking out power to thousands. Some of the damaged structures were historic buildings.
Bricks, debris and crushed cars litter the streets, and power, water and gas lines have been cut.
The quake was centered between San Francisco and Sacramento. Most of the damage is in and around the town of Napa, in northern California's picturesque wine-making region.
Experts have warned of dozens of aftershocks in the coming days.
California Governor Jerry Brown has declared a state of emergency in parts of northern California.
Sunday's quake was the biggest to jolt the San Francisco Bay area since a 6.9 quake hit the city in October 1989, killing more than 60 people.
