During the past decade intense research has been focused on the fault rupture propagation through soft soil deposits. It has been shown that the mechanism of fault rupture propagation is affected by the fault type, the magnitude of fault displacement, the fault dip angle and the mechanical properties of the soil material overlying the fault tip.

Permanent soil deformations may develop as a consequence of an abrupt fault rupture during a seismic event.
