中文摘要：

2014年11月22日在青藏高原东缘的鲜水河断裂带上发生了康定Ms6．3地震。通过分析康定Ms6．3地震的震源机制解、余震分布特征以及震害基本情况，对比了鲜水河断裂带南东段各次级断裂的全新世活动性特征，认为此次地震的发震断裂为鲜水河断裂带南东段的色拉哈-康定断裂，并初步判断该地震可能为一次强震的原地复发事件。同时，综合地表变形特征及震害特征等情况，认为此次康定地震没有出现具有构造意义的地表破裂，其造成的房屋震害与建筑物结构密切相关．

英文摘要：

On Nov. 22, 2014, the Kangding Ms6. 3 earthquake occurred on the Xianshuihe tectonic belt at the eastern margin of the Tibetan plateau. This article analyzed the focal mechanism solution, the distribution characteristics of aftershocks and the basic situation of damage of Kangding Ms 6. 3 earthquake, and compared the characteristic of Holocene activity of each secondary fracture in the south eastern Xianshuihe fault zone. The authors believe that the seismogenic fault is the Selaha-Kangding fault. Meanwhile, integrating the Kangding earthquake ground surface deformation and damage characteristics, the authors consider that Kangding earthquake did not show tectonic significance of surface rupture, and the building damage was closely related with the structure of buildings.
