摘　　要：为深入认识2014年1月7日乳山市附近海域M4.3地震的特性,为该区域的建筑结构抗震设计及核电抗震设计提供有价值的参考资料,对此次地震的地震动记录进行了分析,并与设计谱进行了比较;并根据地震灾害现场调查,简要阐述了此次地震中的一些典型的破坏现象,提出了有关农村民居抗震设防的意见与建议。On January 7, 2014, an M4.3 earthquake occurred in the sea area near RuShan city. In order to further study the earthquake characteristics and to provide reference material for building structure seismic design and the seismic design of nuclear power in this area, the ground motion characteristics of the earthquake is analyzed and compared with design spectrum. Finally, according to earthquake damage survey, some typical damage phenomenon of the earthquake is briefly expounded in the paper, and some opinions and suggestions of effective reinforcement methods for rural building are provided.
