Instructions
The following questions are based on Figure 36-3, a detailed topographic map of the San Andreas Fault, Figure 36-5, a stereogram of the San Andreas Fault in the Carrizo Plain National Monument, and Figure 36-6, a portion of the “McKittrick Summit, California,” quadrangle. “Wallace Creek” is an offset stream that has been labeled for you on Figure 36-6. Most of the movement between the Pacific Plate side and the North American Plate side of the San Andreas Fault is released abruptly after years of accumulating strain—at which time the fault ruptures with a displacement of several meters. Further, it appears that different segments of the fault remain locked for different periods of time. In a general way, the size of an earthquake expected to occur along a segment of the fault system relates to the length of time the fault accumulates strain before rupturing. The longer the strain accumulates, the larger the earthquake when the fault finally ruptures.
