About 300 quakes shook Southern California on Sunday
SOUTHERN CALIFORNIA -- Slabs of broken concrete, shattered glass and craters remain a common scene in Southern California on Monday.
No injuries have been reported after about 300 quakes shook the region throughout the entire day on Sunday.
Most of them were small to moderate-sized tremors but the strongest registered a 5.5.
The swarm was centered east of San Diego.
And Californians can expect more.
Seismologists expect thousands more over the next several days.
