| 摘 要： | 河北磁县西部北西西向南山村－岔口活动断裂为北西西向磁县活动断裂西段，全长３５ｋｍ，又可再分为东西两段。全新世时期该断裂有多次活动，活动方式以具左旋性质的正倾滑为主。１８３０年磁县７．５级地震时，南山村－岔口断裂带出现新的地表破裂，地表垂直位移多处为２～４ｍ，最大约７ｍ。据目前资料，该断裂带最新两次地震事件的时间间隔约为３５００ａ。最近获取的位于磁县最高峰老爷山庙宇碑文资料，补充说明了邻近岔口活动断裂带的古建筑物在１８３０年地震中的严重破坏

| 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 |
