摘要
本文介绍了耿马7.2级地震的某些震害现象,通过简单的机理分析,认为这次地震竖向力作用比较突出。和发震构造的活动性状联系起来考虑,估计这次地震强烈的竖向震动可能与发震断层垂直运动分量较大有关。
This paper introduces some of the earthquake hazard phenomena caused by the M7.2 Gengma earthquake. Through brief analysis of the mechanism of such hazard phenomena, the paper concludes that the M7.2 event has produced remarkable vertical force. Jointly considering the pattern of motions of the seismogenic structures, it is cstimated that the intensive vertical vibrations caused by the event might be associated with fairly large component of vertical motion on the part of the seismogenic fault.
