| 摘 要： | 金沙江—红河断裂是一条超地壳大断裂，为云南地区重要的构造边界，把云南地区划分为东、西两个部分。本简要介绍了云南东部地区主要活动断裂的活动性质，结合发震构造标志、地震破裂围空特征和大震重复周期等分析了红河断裂以东(含红河断裂带)地区的大震危险性，认为云南东部地区近期大震的危险地点有2个：小江断裂中段东支和石屏—建水断裂带石屏以东地区。

| Abstract: | Jinshajiang-Honghe fault is a super crustal one,which is the important boundary of structures in Yunnan Province,dividing Yunnan region into east part and west part.This paper has briefly introduced the property of active faults on the east side of Yunnan.Combining the marks of seismogenic structure,gap characteristics of seismic rupture and recurrence of great earthquakes,it has analyzed the risk of great earthquake in the eastern region of Honghe fault (including the Honghe fault).It is considered that there are two risk locations in recent period in the eastern region of Yunnan.They are the eastern branch in the middle of Xiaojiang fault and the eastern region of Shiping of the Shiping-Jianshui fault. |
