What might explain this variation in scarp height?

The following questions are based on the “Mt. Dome, California,” quadrangle (Map T-24; enlarged to scale 1:48,000; contour interval 40 feet) and the stereogram of the same region (Figure 36-5; north is to the left side of the page). Three prominent fault scarps can be seen running north to south across the map, and will be referred to as the “western” fault, the “central” fault, and the “eastern” fault. These fault scarps are the result of normal faulting (41°49'39"N, 121°33'15"W). What will be an ideal response?
