摘要
介绍了在忻州5.1Ms地震的现场,利用平均震害指数确定宏观震中和烈度划分的工作情况,讨论了几个村庄受害较重的原因以及收集到的宏观前兆异常,并结合构造条件分析了这次地震烈度偏低的原因。
In this paper the author introduces the field work determining the macroepicenter and classifying the intensities using average damage indexes, discusses the reasons of the heavier damages in several villages as well as the collected macroprecursor phenomena and analyses the reason why the intensity of it is comparatively lower in the light of the faults and crustal structure.
