Why Does Los Angeles Have Earthquakes?

The movement along the San Andreas Fault and the several other faults within the San Andreas Fault System, which constitute the tectonic border between the Pacific and North American tectonic plates, is the primary driving factor behind earthquakes in California.

Why is Los Angeles prone to earthquakes in the first place?When the North American and Pacific Plates move in opposite directions, they frequently grind against one other, resulting in an earthquake (Murck, Skinner, & Mackenzie, 2010).The existence of hundreds of fault lines, many of which are related to the San Andreas Fault, contributes to the high frequency of earthquakes in Los Angeles and California.
