静海台地磁短周期变化异常与其附近地震的关系

RELATIONSHIP BETWEEN SHORT PERIOD VARIATION ANOMALIES OF GEOMAGNETISM AT JINGHAI STATION AND EARTHQUAKES OCCURRED NEAR IT

  • 摘要: 近年来的一些研究表明,由于地震前孕震区地下介质的电性结构的变化,将导至地磁短周期转换函数发生异常变化。本文通过对1991年唐山5.2、5.6级地震前后静海台地磁短周期转换函数参数的计算及其结果的分析和研究,提取出了可靠的地震短临前兆信息,确立了将其应用于唐山地区5级以上地震预报的短临异常特征及其指标。

     

    Abstract: The research result in recent years show that the electric property structure changes of subsurface medium in seismogenic zone before earthquakes will result in anomalous variation of short period transfer characteristic of geomagnetism. This paper, by calculation of short period transtfer characteristic of geomagnetism at Jinghai station before and after the1991 Tangshan M5. 2 and M5. 6 earthquakes and by analysis of its result, has proposed a reliable short term and imminent seismic precursory information and determined the short term and imminent anomalous characteristics and index for the prediction of earthquakes of M≥5 in Tangshan region.
