The Temblor Range is being pushed up by faults on both sides of the range and in the middle. These faults are blind thrust faults, meaning that they are thrust faults which do not come to the ground surface. It is not clear to geologists how the thrust faults connect to or relate to the San Andreas fault at depth. The thrust faults are much smaller than the San Andreas. The reason the Temblor Range may appear more impressive than the offsets along the San Andreas fault is that, at the base of the Temblor Range, the motion along the faults is vertical.
Vertical relief is much easier to see than horizontal displacement.
The Caliente Range, along the western margin of the Carrizo Plain, is full of faults and folds, but most of them are no longer active. The only active faults that reach the surface are at the southern end of the Caliente Range, near Cuyama Valley. You can learn more about the Caliente Range in the Carrizo Plain Geologic Tour guide. The U.S. Geological Survey has compiled a comprehensive list of frequently asked questions related to earthquakes and faults.
