| 摘 要： | 以嘉峪关台的原始资料为依据，着重探讨了肃南5．3级地震前祁连山西段的地震活动性异常。将本台的地磁Z分量与兰州、天水地磁台进行比较，结果认为：肃南5．3级地震的发生基本符合祁连山西段地震活动的周期性特征，前兆资料无明显的临震异常显示，但本台的自然电场，地磁日幅差和Z分量的日均值资料有明显的短期趋势性异常显示。

| Abstract: | Seismic anomalies of western Mt.Qilian before southern Gansu earthquake with Ms5.3 are discussed on the base of the data recorded by Jiayuguan station.Compared geomagnetic Z component at Jiayuguan,Lanzhou and Tianshui stations,the results show:the characteristics of the event are agreed with the seismicity period in western Mt.Qianlian,impending anomalies are not sensible,but the natural electric field,geomagnetic daily value and Z component are sensible in short period. |
