用张家口台资料分析1989年10月大同-阳高地震序列

THE ANALYSIS OF DATONG-YANGGAO EARTHQUKE SEQUENCE OF OCT.1989 BY SEISMIC DATA FROM ZHANGJIAKOU STATION

  • 摘要: 1989年10月18日起,在大同-阳高一带相继发生了一群中强地震。其地震序列与以往发生在该区域的大多数地震不同,属主震群型,它既有震群型特征,又具有主余震型特征,并且强余震的间隔时间具有韵律特征。震后对张家口台的资料分析结果表明,只要充分利用单台资料,并正确分析地震序列特征,对地震现场的监视预报,具有很好的实用价值。

     

    Abstract: A group of moderately strong earthquakes has occured in Datong-Yanggao area since Oct. 18 1989. This sequence, of which the characteristics are different from that of the earthquakes occured before in the same area, belongs to main shock-swarm type. It is characterized by either main shock-after shocks type or swarm type. It occured which initially includes several moderately strong events and was followed by the rapid attenuation of seismic enerage with strong after shock periodic fluctuation. We have made an analysis by using the seismic data of Zhang Jiakou station after the Datong-Yanggao main shock. The results have shown that the correct analysis for the characteristics of the earthquake sequence by sufficient single station data is of great significance for in situ seismic monitor and prediction.
