| 摘 要： | 2016年2月11日新疆新源县发生MS5.0地震，极震区烈度为Ⅵ度。综合现场调查及地震等震线分布情况，初步判定本次地震的发震构造为阿吾拉勒山南缘断裂。对灾区乡镇的房屋进行调查，发现部分土木结构房屋未进行过抗震设计，在本次地震中破坏较为严重；部分砖木结构房屋地基未按照规范施工，在震动荷载作用下出现不均匀沉降，致使房屋墙体被拉裂、倾斜。数月前灾区发生过强降雨、冻融灾害，加之多次地震灾害叠加，造成本次地震房屋破坏率高、房屋破坏程度重。

| Abstract: | An MS5.0 earthquake occurred on February 11, 2016 in Xinyuan Country, Xinjiang, at a focal depth of 9 km. The earthquake intensity was VI degrees. Based on a field survey and a related data analysis, we reached two conclusions. First, the seismogenic structure producing this earthquake was located at the south margin of the Awulale mountain fault. The fault strike of is EW, the tendency is north and the dip is 20°~70°. There is a mutual influence between this fault and the Kashi River fault, which caused the Xinyuan-Hejing M6.6 earthquake on June 30, 2012. Second, most disasters caused by this earthquake were due to the fact that many buildings were old and the civil structure was self-built, not following any earthquake-resistant design. Therefore, after the earthquake, some buildings were unsafe. |
