A 4.0-magnitude earthquake struck halfway between Salinas and Soledad at 9:25 p.m. Sunday.
The epicenter was about 13 miles north of Soledad and 15 miles east of Salinas, according to the USGS.
The quake came less than an hour after the San Francisco Giants won the 2012 MLB World Series in Detroit by trampling the Tigers with a 4-game sweep.
Two small aftershocks, magnitudes 2.1 and 2.4, followed soon after, according to the USGS.
There were no immediate reports of injuries or damages.
