根据岩石受力过程的应变、破裂时产生的局部地磁场异常变化和电磁辐射现象 ,运用地磁短周期转换函数法和地磁场垂直分量加卸载响应比法结合电磁辐射现象的分析 ,可达到对地震的中短临异常跟踪预报的目的。由上海及邻近地区 2 0世纪 90年代发生的二次中强地震震例可得到较好的验证。
According to the process of rock stress strain, the local magnetic field anomalies and electromagnetic radiation phenomenon caused by the rupture, the use of geomagnetic short-period transfer function method and the vertical component of geomagnetic field loading and unloading response ratio method combined with the phenomenon of electromagnetic radiation can reach the earthquake The short and medium-term anomaly tracking the purpose of the forecast. The second moderate-to-strong earthquakes that occurred in Shanghai and its neighboring areas in the 1990s can be well verified.
