Abstract

An earlier analysis showed that fault rupture may be deflected around a heavy building founded on a sedimentary layer directly over a strike-slip fault. In this note the analysis is extended to the case of a sloping sedimentary hillside overlying a vertical fault in basement rock. Here, too, it is found that the presence of the hillside may cause the fault surface to be deflected from the vertical, in a downhill direction, as it nears the ground surface. The amount of deflection depends principally on the steepness of the slope, but also on the horizontal distance of the fault from the toe of the slope.
