| 摘 要： | 以合肥台跨郯庐断裂短水准数据为基础,结合华东地区中强震及安徽地区小震释放能量分析了历史测量资料在地震期间的变化,研究了辅助资料对测量资料的影响,得出:(1)降水虽可能造成敏感地块的断层形变异常,但在区域应力作用断层到一定强度时断层形变异常仍具有一定的前兆意义.(2)华东地区中强地震、安徽地区小震(群)与合肥台断层形变存...

| Abstract: | In this paper,the characteristics of fault deformation evolution was analyzed based on the cross-fault leveling data of Hefei Seismic Station during earthquake of its surrounding area,and the cross-fault leveling data influenced by assisting observation data also have been studied.The conclusions are as follows:1) though the rainfall can lead to the fault deformation,the fault deformation anomalies still have precursory significance to some degree when the regional stress have intensity effect on the fault.... |
