Abstract: The paper deals with new information about the Nanshancun-Chakou active fault.The total length of the zone is about 35 km.It is divided into two segments, respectively 5km and 15km.The style of the active fault is normal-dip-slip accompanied by sinistral stike-slip.The active fault had many times of activity during Holocene.There was ground surface fracture zone along the active fault in 1830 earthquake.The northern side of the fault fell down.The vertical displacements on the ground along the fault are mostly 2-4m.The recurrent interval of the latest two times of destroyed earthquakes along the fault was about 3 500a according to the research.The paper will show the evidence to explain the serious destruction of the ancient temples along the fault in the 1830 earthquake from the the records carved in stones of the temple.
