| 摘 要： | 安徽地区处于华北板块与扬子板块沿着大别造山带的陆一陆碰撞变形带，构造背景复杂多样，断裂十分发育。郯庐断裂带长期控制着两侧的构造格局，大别山东缘的霍山地区多条断裂在晚第四纪有新活动。史料记载表明安徽地区历史地震以中强震为主，最高震级为M6 1/4级。根据区域地震地质、历史地震近年最新研究成果，对第四纪特别是晚第四纪以来的断裂活动习性做出归纳和分类，并分析历史地震、1970年后有仪器记载以来中等强度地震和小地震密集与断裂活动的相关性，为中长期地震预测提供依据。

| Abstract: | Located in continent-continent collision between the North China tectonic block and Yangtze tectonic block,the Anhui area formed a deformation belt along the Dabie orogenic belt.The tectonic background of this area is complicated and diversified and fault tectonics of it is fully developed.The Tan-Lu fault zone controls the tectonic pattern of both sides for a long time;there are many faults in Huoshan area on the eastern margin of Dabie Mountains have activities in the late Quaternary.Historical earthquake... |
