【摘要】 地震的发生是地壳深部在特定应力条件下构造活动的结果,均衡重力异常图包含着丰富的地质构造信息,它是岩石圈静力与动力学过程的综合反映。本文通过收集地震资料,结合保山-巍山地区均衡重力异常,分析保山—巍山地区地震活动性与均衡重力异常的关系,总结出增强地震活动性的均衡重力异常特点。更多还原

【Abstract】 The occurrence of earthquake is the result of tectonic activity in the deep crust under given stress conditions.Isostatic gravity anomaly includes rich information about geological structure,and it is the synthetical reflection of static and dynamic process of the Lithosphere.Through collecting seismic data and combining isostatic gravity anomaly in Baoshan—Weishan area,this paper analyzes the relationship between seismic activity and isostatic gravity anomaly in Baoshan—Weishan area,and summarizes the characteristics of isostatic gravity anomaly that could enhance seismicity.更多还原
