4 earthquakes shake Southern California overnight

AVALON, Calif. (KABC) -- Four earthquakes jolted different parts of Southern California overnight.

The first two small quakes, magnitudes 1.8 and 2.5, were reported in Fountain Valley shortly after midnight. The other two shook Avalon within the same hour.

The U.S. Geological Survey says the strongest quake was a magnitude 4.1 centered 42 miles south-southwest of Avalon around 12:42 a.m. Two minutes earlier, a small 3.5 quake rumbled the same area.

The earthquakes in Fountain Valley were significantly smaller, but at least one viewer in Huntington Beach reported that one of the quakes felt and sounded like an explosion.

There were no reports of damage or injuries.
