The San Andreas fault produces earthquakes, but not volcanic activity.
Earthquakes occur along a fault. Near the San Andreas fault lots of earthquakes occur.
A fault is a fracture in a large volume of rock, generally caused by tectonic activity. Faults, such as the San Andreas Fault in California, are often regions of frequent seismic activity for the same reason.
The average amount of diplacement along the San Andreas Fault is 2 to 5 centimeters (1 to 2 inches) per year.
California's seismic activity is the result of the many active faults it lies upon, most prominantly, the San Andreas Fault. One of the reasons that California has so many earthquakes is that the San Andreas fault has a "bend" that creates large amounts of friction as the plates slide next to each other.

AnswerAccording to the USGS, the plates along the San Andrea fault move about 1.7in per year.
The San Andreas Fault is a transform fault (also known as a strike-flip fault). It is where two plates are sliding past each other in opposite directions.
