2008年5月12日汶川大地震引发了山体滑坡、滑坡、泥石流等一系列地质灾害。通过实地调查和遥感解译，确定了四川省16个重灾县的11308个地质灾害。本文分析了这些地质灾害的分布，特别是地震引发的滑坡。不出所料，最严重的地质灾害与主断层和上盘有关，尽管有些发生在远离主破裂带的深切河谷中。由于地震的高地震强度，大多数大型滑坡以高速和相当远的距离移动。
The Wenchuan Earthquake on 12 May 2008 triggered a large number of geo-hazards including landslides, slope collapses and debris flows. Field investigations and remote-sensing interpretation identified 11,308 geo-hazards in 16 seriously damaged counties in Sichuan Province, south west China. The paper reports an analysis of the distribution of these geo-hazards, particularly the earthquake-triggered landslides. Not surprisingly, the most significant geo-hazards were related to the main fault and on the hanging-wall side, although some occurred in deeply incised river gorges further away from the main rupture zone. Due to the high seismic intensity of the earthquake, most of the large landslides moved at high speed and for considerable distances.
