A transform plate boundary developed where the Pacific Plate was in contact with the North American Plate and the volcanism ceased in central California. Farther east, the continent began to rift apart in the Basin and Range Province.

Boundary zones are the intersections of contrasting geologic forces or environments and consequently much of the geologic evolution is recorded or best displayed at these boundary zones. The scenic coastline of California extends nearly 1,100 miles and is another shifting geomorphic boundary.
15 Φεβ 2021 · This historically significant report provides an overview of the history, geology, geomorphology, geophysics, and seismology of the most well known plate-tectonic boundary in the world. Generalized California Plate Tectonic History:
Movement in narrow zones along plate boundaries causes most earthquakes. Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up.
To answer that let’s look at California’s current plate tectonic setting. As this map shows, we have a number of plate boundaries within or near the state. Notice at the northern part of California, we have a divergent plate boundary or an offshore seafloor spreading center where new oceanic crust forms and then is pushed away.
According to the theory of plate tectonics, the San Andreas Fault represents the transform (strike-slip) boundary between two major plates of the Earth’s crust: the Northern Pacific to the south and west and the North American to the north and east.
In the Mesozoic, the plate boundary was a subduction zone dipping to the east under North America, and that shape is preserved as powerful evidence of the fundamental geometry of that boundary. The modern transform plate boundary, in contrast, is vertical.
