摘要
2018年9月4日新疆伽师M S5.5地震的震感范围较广,现场调查的等震线与余震展布方向均呈NE。地震序列表现为前震—主震—余震型,主震震源机制为NS向主压应力下的走滑断错。地震灾区最高烈度为Ⅶ度,不同结构的建筑物震害特征受场地条件影响较为明显,安居工程经受住了地震检验。
Xinjiang Jiashi MS5.5 earthquake on September 4th,2018 had a wide range of seismic sensations.The isoseismal lines and aftershocks in the field survey were NE.The seismic sequence was of foreshock-main shock-aftershock type,and the focal mechanism of the main shock was strike-slip fault under NS-direction principal compressive stress.The highest intensity in earthquake-stricken area wasⅦ.The characteristics of earthquake damage of buildings with different structures were obviously affected by site conditions,and the housing project had withstood the earthquake test.
