Explain where earthquakes are most likely to originate

Earthquakes are more prevalent on Fault Lines . . . In the City of Hollister, in California . . . Down the peninsula from San Francisco, on the San Andreas Fault-line . . . They experience Earthquakes everyday . . . But they are just too small . . . But still, some are still ground shakers . . . All bottles in liquor stores are stored back on the shelves . . . Way back, so you have to reach . . . And there are usually wires or strings of some sort to keep the bottles from falling to the floor and breaking. That's the San Andreas Fault though.
