The San Andreas Fault runs along the Pacific Coast.

The San Andreas Fault is a major fault line that extends along the Pacific Coast, particularly in California, where it forms the boundary between the Pacific Plate and the North American Plate. This fault is responsible for significant seismic activity, including several major earthquakes in the region’s history. As the plates move, they cause stress to build up, eventually releasing energy in the form of earthquakes. The San Andreas Fault is particularly well-known for its role in shaping California’s landscape and poses a major earthquake risk for the areas it runs through, making it a key focus of geological studies.
