Abstract: The western Sichuan plateau lies on the eastern margin of the Qinghai-Xizang Plateau,where abundant violent geologic hazards such as collapse,landslide and debris flows frequently occur because of complx geological tectonics,active endokinetic/exokinetic processes and severe tectonization.These geologic hazards are generally aligned along active structural zones, and mostly controlled by geological structures,present-day tectonic movements,topography and geomorphology,rainfalls and human’s activities in the study area.
