Earthquake-triggered landslides have aroused widespread attention because of their tremendous ability to harm people's lives and *** best way to avoid and mitigate their damage is to develop landslide hazard maps and make them available to the public in advance of an *** construction can then be built according to the level of hazard and existing structures can be retrofit as *** recent years various approaches have been made to develop landslide hazard maps using statistical analysis or physical ***,these methods have *** study introduces a new GIS-based approach,using the contributing weight model,to evaluate the hazard of seismically-induced *** this study,the city and surrounding area of Dujiangyan was selected as the research area because of its moderate-high seismic *** parameters incorporated into the model that related to the probability of landslide occurrence were:slope gradient,slope aspect,geomorphology,lithology,base level,surface roughness,earthquake intensity,fault proximity,drainage proximity,and road *** parameters were converted into raster data format with a resolution of 25×25m2 *** of the GIS correlations shows that the highest earthquake-induced landslide hazard areas are mainly in the hills and in some of the moderately steep mountainous areas of central *** highest hazard zone covers an area of 11.1% of the study area,and the density distribution of seismically-induced landslides was 3.025/km2 from the 2008 Wenchuan *** moderately hazardous areas are mainly distributed within the moderately steep mountainous regions of the northern and southeastern parts of the study area and the hills of the northeastern part;covering 32.0% of the study area and with a density distribution of 2.123/km2 resulting from the Wenchuan *** lowest hazard areas are mainly distributed in the topographically flat plain in the northeas
