前兆观测资料的变化与弱震活动的关系

The Variation of the Precursor Observation Data and Its Relation with the Weak Seismicity

分析了江苏新沂地震台的短水准、地电阻率两种前兆资料的变化情况,研究了其与郯庐断裂带南段地震活动的关系。结果表明,新沂台前兆资料的变化能发现郯庐断裂带南段的强烈活动,对该断裂带上3.0级以上的地震有一定程度的反映。

Two kinds of precursor observation data(shortrange leveling and ground resistivity)of Xinyi seismic station in Jiangsu.are analyzed,and the relation with the weak seismicity of south segment of Tanlu fracture zone is studied.The conclusion shows that the variation of the data can disply the strong activity of south segment of Tanlu fracture zone,and have some reflection for M＞30 earthquakes of the fracture zone.
