Abstract: Recent displacements along the fault will certainly produce pronounced markings on the landforms. Therefore, it is possible to acquire some important informations about seismic activity along active fault by using these land’ features-faulted landforms. Faulted landforms along the Xianshuihe fault indicate that the fault is characterized by intermittent earthquake displacements which follow the characteristic earthquake model for the recurrence of earthquakes with the same size at the same place. The pattern of the progressive evolution of offset streams might indicate that the slip rate of the fault in the same place is relatively constant during a certain period. Therefore, faulted landforms can be used as an important indicators in the research of seismic activity.

Key words: Xianshuihe fault, Faulted landforms, Characteristic earthquake, Fault slip rate
