UPDATE (3:30 p.m.) - Seismologists have slightly revised the magnitude of the earthquake down to 4.7.
ORIGINAL STORY: A 4.8 magnitude earthquake struck about 20 miles east of Salinas on Tuesday.
It happened at 12:42 p.m.
The U.S. Geological Survey reported that the quake occurred along the San Andreas Fault. The epicenter area is in a rugged mountain range, with agricultural areas to the west.
KSBW-TV reported that the San Benito County building was evacuated as a precaution but there had been no reports of damage or injury.
People in northern San Luis Obispo County reported feeling the quake.
It happened a day after a 4.5 quake rattled the Bay Area. That quake was centered in Pleasant Hill but was felt more than 150 miles away.
The shaking was enough to knock items off store shelves, but no injuries or serious damage were reported.
Veteran seismologist Lucy Jones says the two quakes are too far apart to be related.
