摘要

宿松—枞阳断裂卫星影像清晰,是一条对构造、地貌、中新生代盆地有着控制意义的断裂。本文对该断裂所处的区域地震地质构造背景进行了分析,结合断裂的发育历史,选择典型剖面,对断裂的最新活动特征进行调查。根据野外地质考察和断裂沿线地震活动统计结果,对断裂未来的地震危险性进行了定量评估。分析认为,该断裂晚第四纪以来仍然有所活动,但活动强度已减弱,未来可能发生无地表位错的中强地震,最大震级综合判定为M5.5。
Susong-Zongyang Fault has a clear satellite image and is a fault with controlling significance for the structure,geomorphy and Mesozoic-Cenozoic basins.This paper analyzes regional seismo-geological structure background of the fault.Based on the fault's development history and typical profile,the recent active characters of the fault was investigated.According to field geological investigation and statistics about seismic activity along the line of the fault,a quantitative evaluation of the seismic hazard of the fault in the future was conducted.Results show that the Susong-Zongyang Fault is active in the late quaternary period,but the tectonic movement is very weak and potenlial earthquake hazard is evaluated as magnitude M5.5.
