【摘要】 通过倾斜矢量法和垂直形变剖面图分析法,对安庆MS4.8地震前肥东短水准数据进行了分析,结果显示肥东台短水准数据在安庆地震前出现异常变化。对比分析了安庆地震与九江地震前肥东短水准异常形态的差异,认为安庆地震和九江地震的震源机制不同,震前应力积累在肥东台附近的不同类型可能是两次地震前肥东短水准异常形态不同的主要原因。更多还原

【Abstract】 Using tilt vector method and vertical deformation profile method respectively,we analyzed the data of short leveling in Feidong Station.The result showed that the data of short leveling in Feidong station appear anomaly before Anqing MS4.8 earthquake.Comparing and analyzing the difference of short leveling data anomaly in Feidong between Anqing earthquake and Jiujiang earthquake,we inferred that the difference of focal mechanism of the two earthquake and the different stress accumulation process before the two earthquakes was the main reason.更多还原
