摘    要:根据历史地震资料的考证结果,734年天水地震的极震区位于秦州中都督府、麦积都尉一带,今天水市秦城区、北道区和麦积山一带,震中烈度达Ⅹ度,震级71/2级左右。其等震线长轴方向为NW向,大致与西秦岭北缘断裂带的甘谷-武山断裂段相吻合,极震区正好位于甘谷-武山断裂段的东端。综合分析认为,734年天水71/2级地震的发震构造为西秦岭北缘断裂带的甘谷-武山断裂段东端

关 键 词:734年天水地震  历史地震考证  发震构造  西秦岭北缘断裂

Abstract:Tianshui area locates at the northeastern margin of Qinghai-Tibetan plateau and the middle segment of the north margin of western Qinling tectonic zone.In history,several strong destructive earthquakes happened in the area.Because of the very long history and that the historical records are not quite clear,it is very difficult to study them in nowadays,and most of them became historical knotty problems.The Tianshui earthquake in 734 AD is one of the large earthquakes.On March 23,734 AD,a large earthquake ha
Keywords:Tianshui earthquake in 734 AD  Historical earthquake textual research  Causative structure  Northern margin of western Qinling fault
