Friction along the fault
When rock moves it depends on how much friction there between the opposite sides of fault.Friction is there forces that opposes the motion of one surface as it moves across another surface.Friction exists because surfaces are not perfectly smooth.where friction
Along a fault is low, the rocks on both sides of the fault slide by each other without much sticking.
