Why does California have so many earthquakes?

Southern California Earthquakes and Faults. The earthquakes of California are caused by the movement of huge blocks of the earth’s crust- the Pacific and North American plates. The Pacific plate is moving northwest, scraping horizontally past North America at a rate of about 50 millimeters (2 inches) per year.

Will California fall into the ocean?

No, California is not going to fall into the ocean. California is firmly planted on the top of the earth’s crust in a location where it spans two tectonic plates. The strike-slip earthquakes on the San Andreas Fault are a result of this plate motion.
