Rescue workers are searching for survivors after destructive waves of mud came down the hills in southern California, slamming everything in sight.
The force of the mudslides was so massive that it destroyed homes, uprooted trees and washed away dozens of cars.
Hundreds of first responders in Santa Barbara County waded through waist-high mud while others flew over the devastation searching for survivors.
So far, 13 people have killed and more than 160 others were injured.
The death toll is expected to rise.
More than 50 people have been rescued already but many places are still inaccessible. Several roads are closed, including the major Highway 101.
