A small part of California that lies on the oceanic Pacific Plate is the coastal region along the western side of the state, particularly areas like the San Andreas Fault. This fault marks the boundary between the Pacific Plate and the North American Plate, with the Pacific Plate extending offshore in the Pacific Ocean. Notable locations include coastal cities like San Francisco and Los Angeles, where geological activity is influenced by the movement of these tectonic plates.
