古城康定,是甘孜藏族自治州的首府,川藏公路咽喉,又是川西高原政治、经济、文化和交通重镇,人口密集。规模巨大的几条活动断裂在附近复合交汇,一条活动断裂通过城区,地质结构复杂,构造运动强烈。自古以来地震活动频繁,曾发生过多次强烈地震,近年小震活动不断,随着鲜水河断裂北段相继发生多次强烈地震,南段大震危险性有增强的趋势。因此, The ancient city of Kangding, is the capital of Ganzi Tibetan Autonomous Prefecture, the Sichuan-Tibet Highway throat, but also the western Sichuan Plateau political, economic, cultural and transport center, densely populated. A large number of active faults in the nearby composite intersection, an active fault through the city, the geological structure is complex, strong tectonic movement. Earthquakes have been frequent since ancient times, and many strong earthquakes have occurred. In recent years, small earthquakes have been continuously occurring. With the successive strong earthquakes in the northern segment of the Xianshuihe fault, the danger of the large earthquakes in the southern segment tends to increase. therefore,
