Normal Fault

a fracture-type tectonic displacement of rocks. In a normal fault, the relative displacement of rocks occurs either vertically or along a steeply inclined fracture in such a way that the rocks of the hanging wall are shifted downward and the rocks of the footwall move upward. Normal faults often occur in pairs, forming depressions called grabens or elevations called horsts. Step faults are also common. Normal faults form primarily under conditions of tension. Some normal faults have amplitudes of 4 and 5 km.
