| 摘 要： | 本文对嘉峪关南５．４级地震前嘉峪关观测点观测的断层气组分氡、汞、氢的异常进行了分析研究，并通过与跨断层水准测量及地震活动性的对比分析，证实了上述异常确系５．４级地震的前兆反映。本文还对该观测点的地质构造特征进行了研究，认为其所处的构造部位对多方式力源有敏感性。

| Abstract: | In this paper,we introduced the anomalies of fault-gases Rn,Hg and H_2 at Jiayuguan station be-fore the south Jiayuguan M5.4 earthquake. By comparing with the seismicity and leveling surveyacross the faults,it is shown that the anomalies are indeed the precursor of this earthquake. By study-ing the features of geological structures at the observation point,it is considered that Jiayuguan fault-gases correspond well to many earthquake because the point is situated in the position where the struc-tures are sensitive to multi-way force sources. |
