【摘要】 2014-11-22,位于青藏高原东部的四川省康定县发生了Ms 6.3级地震,为一次左旋走滑事件,发震构造为鲜水河断裂带南东段的色拉哈断裂。对地震灾区进行的地表破裂特征调查和房屋震害调查表明:1.地震没有形成明显的地表破裂,地表破裂主要表现为张性地裂缝、喷砂冒水、小型滑坡、道路边坡失稳及滚石等;2.烈度图长轴方向与鲜水河断裂走向一致;3.房屋震害具有农牧区房屋破坏普遍,城镇房屋破坏较轻的分布特点;4.2014-11-25的Ms 5.8级强余震,加深了灾区破坏程度。更多还原

【Abstract】 On November 22,2014,Kangding in Sichuan of China Ms 6. 3 earthquake happened. This earthquake is one sinistral strike-slip event. The seismogenic structure of this earthquake is the Selaha fault which is the south eastern segment of the Xianshuihe fault. We have surveyed the surface rupture characteristics and building damage characteristics during Kangding Ms 6. 3 Earthquake. Survey results show that: 1) There are no obvious surface rupture formed by this earthquake,surface deformations mainly include ground fractures,Sandblasting water,minor landslips,roads slope instability and rolling stones. 2) The long axis direction of this earthquake intensity consistent with the trend of the Xianshuihe fault. 3) Pastoral areas’ buildings damaged generally and town’buildings damaged slightly. 4) on Nov. 25,2014,the Ms 5. 8 earthquake deepened destructiveness of disaster areas.更多还原
