中文摘要：

2017年6月24日四川省茂县叠溪镇新磨村突发特大高位顺层岩质滑坡,造成10人死亡,73人失踪,整个新磨村被毁的重大损失。通过对滑坡所处位置的地形、地质、降雨和历史地震综合分析,该滑坡是由历史上多次强烈地震形成的震裂山体在持续降雨作用下触发的高位坡—碎屑流—堰塞湖灾害链。强烈地震造成的山体内部损伤可持续影响数百年以上,是未来高烈度区地质灾害排查的重点。

英文摘要：

At 5∶ 39 AM on 24 June 2017,a massive high-position landslide-debris avalanche hit the Xinmo village of Diexi town,Maoxian country,Sichuan province,China,causing 10 deaths,73 missing and the whole village to be buried. According to a comprehensive survey of the topography,geology,rainfall and historical earthquakes of the location of the landslide,it was found that the landslide was a typical case of high slope-debris flow-dammed lake disaster chain,which was triggered by successive rainfall and the occurrence was followed by a formation of cracked cliff induced by historical earthquakes. Therefore,it can be inferred that the internal damages developed in cliff generated by earthquakes can affect the stability of rock slope probably hundreds of years later. It should be the concern of geological hazard investigation in the earthquake-hit areas in the future.
