| 摘 要： | 应用多个地震活动参数来判定断裂带分段落活动习性的方法，分析安徽省新生代构造变形带不同分段落的现今活动习性及地震危险性。研究结果表明：安徽省新生代构造变形带中存在着9个具有不同现今活动习性的分段落，其中，霍邱-风台、铜陵-宁国、明光-肥东3个段落现今活动习性处于较高应力背景下的相对闭锁状态．应属于有一定应变积累的潜在中强震危险段落：其它6个段落．现今活动习性处于中等或偏低应力背景下，以频繁或稀疏小震滑动为特征．未来复发中强以上地震的可能性较小。

| Abstract: | Based on the method of using a number of seismic activity parameters to determine activity features of fault zone segments,current seismic activity and seismic risk features of different segments of Cenozoic tectonic deformation zones in Anhui Province are analyzed.The results show that: there are nine segments with different activity features in Cenozoic tectonic deformation of Anhui Province,among which the current activity features of Huoqiu-Fengtai,Tongling-Ningguo,Mingguang-Feidong segments are in a re... |
