摘要
从1989年10月18日开始,山西省大同—阳高—带发生了主震为 Ms 6.1的震群活动。这次震群活动使山西、河北和内蒙遭到了不同程度的破坏,使人民生命财产和经济建设受到严重损失。本文从几个方面详细论述了大同-阳高地震现场工作特点、基本参数、震源机制、地震序列的基本特征和空间分布、前兆异常变化、宏观烈度及震害、地震地质背景和地震灾情。
Beginning from October 18,1989,an earthquake swarm with main shock of magnitude 6.1 occurred in the Datong-Yanggao area,Shanxi province.This earthquake swarm caused damages to varying degrees in Shanxi,Hebei and Inner Mongolia,and life,property and economic construction suffered great losses.From several aspects,the paper depicts in de- tail the Datong-Yanggao earthquakes,including features of on-the-spot seismic investigation, basic parameters source mechanisms,basic characteristics and spatial distribution of the earthquake sequence,abnormal precursory variations,macro intensity and earthquake disas- ter,seismological and geological background,as well as the condition of earthquake disas tets.
