摘要
福建省仙游2013年ML5.0级地震是福建该省年度内发生的最大地震事件。在地震监测以及精定位的基础上,从地震序列、震源深度和震源机制解等方面做了统计分析,并依据震区地质构造图,分析了地面流动重力反映的不同构造部位深部物质的变化及其与断裂构造和地应力的关系,最后从断面凸破模型分析了地震发生的机理,并与地球物理及震源机制解进行相互验证。
In 2013, Xianyou ML5.0 earthquake is the largest earthquake in Fujian province. In this paper,Based on the earthquake monitoring and precise relocation, we made a statistical analysis from the earthquake sequence, focal depth and focal mechanism solution and so on, and on the basis of earthquake tectonic map,analyses the change of deep substance of different tectonic position reflected by the ground gravity flow and its relationship with fracture structures and ground stress. Finally from the fault convex broken model, the paper analyzes the mechanism of the earthquake, and verified the results each other by geophysical and focal mechanism solution.
