THE PRECURSORY ANOMALIES AND SHORT IMMINENT PREDICTION OF THE JIAYUGUAN EARTHQUAKE(M=5.4) ON JAN. 20. 1992

摘要:

本文阐述了1992年元月12日嘉峪关5.4级地震的前兆异常,介绍了该次地震的短临预报及震后趋势判断情况。该次地震的前兆异常空间分布范围小,持续时间短,具有中强震前兆异常时空分布的一般特征。

Abstract:

In this paper, the precursory anomalies of the Jiayuguan earthquake (M=5.4) are expounded. The authors introduce the short imminent prediction to the shock,and the judgement of the post seismic trend. The earthquake has smaller space distribution of precursory anomalies, shorter duration, and general features of space time distribution of precursory anomalies as moderate earthquakes.
