A small earthquake has shaken the Channel Islands off the California coast.

Seismologist Randy Baldwin of the U.S. Geological Survey says the magnitude 4.2 earthquake hit at 12:41 a.m. Thursday according to preliminary measurements.

The USGS says the quake was centered about 40 miles south of Catalina island and about 60 miles off the coast of San Diego.

San Diego police say there have been no reports of any damage or injuries, and officers did not feel any shaking.

Baldwin says the USGS Earthquake Information Center has received about 50 reports of people feeling the temblor, but none of them reported any damages.
