The inventory is the most detailed and comprehensive landslide inventory in the recent publications of landslide inventory related to the 2008 Wenchuan earthquake, it is also the largest landslide inventory for a single earthquake event at the beginning of records. Among of these landslides, 196,007 landslides (account for 99.25%), with a total area of 1,150.622km2 (account for 99.19%), concentrate in an approximate ellipse area with a total area of 44,031km2. The Yinxiu-Beichuan co-seismic surface rupture is the long axis of the approximate ellipse area. The power rules between cumulative landslide number and landslide area having size between 10,000m2 and 1,000,000m2 related to the 2008 Wenchuan earthquake could be represented as a power law relationship, which is lg N(A)=-2.0745A+13 with R2=0.9931. This result indicates a good power law relationship between landslide area and landslide number. The area affected by the 2008 Wenchuan earthquake slightly exceeds the upper bounds determined by single earthquake events all over the world. The inventory of landslides triggered by the 2008 Wenchuan earthquake provides an important basic data for the future research., authors=XU Chong, authorsList=XU Chong, authorCompany=Key Laboratory of

汶川地震滑坡编录结果表明,2008年5月12日汶川地震触发了197481处滑坡,面积约为1160km2 ,大致分布在一个面积约1.1x105 km2 的区域内,是当前汶川地震滑坡最全面详细的编录成果,也是有记录以来单次地震事件触发滑坡数量最多的记录。其中196007处滑坡(占滑坡总数量的99.25%),面积为1150.622km2 (占总滑坡面积的99.19%),分布在一个面积为44031km2 、以映秀—北川地表破裂为近似中心的近椭圆形区域内。分析这196007处滑坡面积与滑坡数量的幂律关系,结果表明,面积在1x104 —1x106 m2之间的滑坡,滑坡面积与滑坡数量累加之间的幂律关系式可表示为lgN (A )=-2.0745A +13,判定系数R 2 =0.9931,表明该滑坡面积区间内滑坡面积与滑坡数量之间具有良好的幂律关系。对比结果表明,汶川地震滑坡影响区面积略高于全球其他地震事件滑坡影响区面积的上包络线。汶川地震滑坡编录成果为后续汶川地震滑坡相关科学研究提供了重要的基础数据。

It is indicated that on May 12, 2008, 197, 481 landslides triggered by Wenchuan earthquake (Mw 7.9) in China, total affected area is about 1, 160km2, distributing in an area of approximate110,000km2 by the latest studies. The inventory is the most detailed and comprehensive landslide inventory in the recent publications of landslide inventory related to the 2008 Wenchuan earthquake, it is also the largest landslide inventory for a single earthquake event at the beginning of records. Among of these landslides, 196,007 landslides (account for 99.25%), with a total area of 1,150.622km2 (account for 99.19%), concentrate in an approximate ellipse area with a total area of 44,031km2. The Yinxiu-Beichuan co-seismic surface rupture is the long axis of the approximate ellipse area. The power rules between cumulative landslide number and landslide area having size between 10,000m2 and 1,000,000m2 related to the 2008 Wenchuan earthquake could be represented as a power law relationship, which is lg N(A)=-2.0745A+13 with R2=0.9931. This result indicates a good power law relationship between landslide area and landslide number. The area affected by the 2008 Wenchuan earthquake slightly exceeds the upper bounds determined by single earthquake events all over the world. The inventory of landslides triggered by the 2008 Wenchuan earthquake provides an important basic data for the future research.
