【摘要】 通过对郯庐断裂带江苏新沂—安徽宿松段历史及现代地震活动性分析、地震地质调查结果及沿线跨断层水准测量结果的综合分析,认为郯庐断裂带新沂—宿松段近期地震危险性主要位于新沂—泗县一带和明光一带,其中新沂—泗县一带近期有发生MS5.0～6.0级地震的活动背景;明光一带近期有发生MS5.0级地震的活动背景。更多还原

【Abstract】 Historical and present seismic activity,geological investigation results and across-fault leveling data of Xinyi-Susong fault segment of Tan-Lu Fault zone are analyzed in this paper.The results show that seismic risk is higher in two areas of the Xinyi-Susong fault segment,one is Xinyi-Sixian area,which may risks of MS5.0-6.0 earthquake,and the other is Mingguang area,which may risks of MS5.0 earthquake.更多还原
