Yes they occur in California because the Pacific and the North American plates are sliding past one another.
Most earthquakes occur in the ring of fire, a large region surrounding the vast Pacific Ocean. There is a lot of active plate movement, and convergent and divergent boundaries cause strike-slip faults to occur. Earthquakes that occur in this region can be in Vanuata, Japan, Alaska, California, Indonesia, and Sumatra.
The most earthquakes occur in Alaska, followed by California.
They mostly occur when the tectonic plates in the earths systems rub against each other and they mostly occur in California.
