Two moderate earthquakes have struck under the ocean near the Channel Islands off the Southern California coast.

The U.S. Geological Survey reports a magnitude 4.5 earthquake struck the sea floor about 14 miles east of San Nicolas Island at 2:45 p.m Sunday.

A magnitude 3.6 quake hit three minutes later in the same spot, 56 miles west of Santa Catalina Island, in an area where the sea floor is about 2,000 feet below the surface.

A sheriff's dispatcher in Avalon on Santa Catalina Island says he did not feel the quake and there have been no reports of damage or injury.
