STUDY ON GEOMAGNETIC ANOMALIES IN AMPLITUDE RATIO BEFORE EARTHQUAKE

  • 摘要: 利用张家口、昌黎和红山台站地磁日变资料, 计算了幅值比。结果表明, 此值是较稳定的, 但往往地震前, 靠近震中台站幅值比会出现大幅持续增高或突跳, 形成明显异常, 对未来震中地点的判断有一定意义。

     

    Abstract: The amplitude ratio of the geomagnetic data in Zhangjiakou, Changli and Hongshan Seismostation is calculated.The results show that the ratio is relatively stable, but the amplitude ratio in the station near hypocenter usually keeps increasing or jumping before an earthquake, and formed obvious anomaly.This feature is significant to the determination of potential epicenter.
