There are varied kinds of the active tectonic landforms in the Changma Fault Zone,including tension fault scarp,pressure fault scarp,landslid, drumlin, earthquake fissure, disintegration deformation of terrace and left slip displacement deformation of mountain ridge and water system and so on.Through analyzing the features of these landforms and comparing with each other, the active kind of Changma Fault Zone can be determined to be left strike slip accompanying with dip slip movement and there have been at least three times of sudden faulting or earthquake events since the later period of the late pleistocene.Those 3 earthquakes resulted in the formation of 3 stages of active tectonic landforms in Changma Fanlt Zone.According to the trench material and the ¹⁴C data, the geolgical dates for the 3 stages of active tectonic land forms are follows.Ⅰ<24450±310yr, 5095±85yr<Ⅱ<Ⅰ, and Ⅲ was produced by the earthquake of 1932.
