Rock faults are ruptures along which opposite faces of rock have moved past each other, parallel to the fracture surface. Earthquakes often accompany this ovement. In Fig., points A and B coincided before faulting. The component of the net displacement AB parallel to the horizontal surface fault line is called the strike-slip (AC). The component of the net displacement along the steepest line of the fault plane is the dip-slip (AD). (a) What is the net shift if the strike-slip is 22 m and the dip-slip is 17 m? (b) If the fault plane is inclined 52° to the horizontal, what is the net vertical displacement of B as a result of the faulting in (a)?
