A related product is a seismic risk map, which expresses the probabilities of destructive ground movement over a region. Seismic forecasts and risk maps are usually based on historic earthquakes along known faults, and although such information provides a useful historic framework, their power as a predictive tool is limited.A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep.
