None of the above

Detailed explanation-1: -A San Andreas earthquake would be classified as occurring on a strike-slip fault. Strike-slip faults are found along boundaries of tectonic plates sliding past each other. A strike-slip fault is a vertical fracture in the earth’s crust that creates horizontal motion, along the line of the fault.
Detailed explanation-2: -strike-slip fault-a fault on which the two blocks slide past one another. The San Andreas Fault is an example of a right lateral fault.
Detailed explanation-3: -The San Andreas Fault-made infamous by the 1906 San Francisco earthquake-is a strike-slip fault. This means two fault blocks are moving past each other horizontally. Strike-slip faults tend to occur along the boundaries of plates that are sliding past each other.
Detailed explanation-4: -In a strike-slip fault, the movement of blocks along a fault is horizontal. The fault motion of a strike-slip fault is caused by shearing forces. Other names: transcurrent fault, lateral fault, tear fault or wrench fault. Examples: San Andreas Fault, California; Anatolian Fault, Turkey.
Detailed explanation-5: -The San Andreas Fault is part of a transform plate boundary that disrupts the topography of an ancient subduction zone.
