摘要
Deep-seated catastrophic landslides,particularly rock or debris avalanches,travel extremely rapidly for long distances,causing severe damage over wide areas.This paper summarizes the geological and geomorphological features of such events,which were induced by earthquakes and rainstorms in Asia,and then uses these features to predict future potential sites of failures.Most of the rock avalanches are preceded by gravitational slope deformation with topographic features,in which small scarps along future head of landslide are the most representative;the scarps can be identified in topographic images made by highresolution airborne LiDAR DEMs and may suggest the instability just before catastrophic failure.
