(Paper pages 119-132) This study is an attempt to examine the Landslide potentials and landslide hazard zonation in Nojian Area. Nojian is located 30 km away in the south- east of Khoramabad, Lorestan province. In order to zonate the hazard of mass movement, first the natural maps including geology, slope, slope direction, landuse, regional-fault maps, the intensity of the earthquake, etc. were prepared. In the second stage this data set was digitalized . Then by drawing on field work , arial photo and digital data from satelite image, landslide – inventory map including falls and sliding were mapped on the base map of the study area. By incorporating natural maps with the landslide inventory map, the extent of sliding in different parameters was obtained. However, through the statistical method (area density) for each parameter like lithology, slope, slope direction, distance from fault, landuse, intensity of the rain, intensity of the earthquake, etc. the numerical value for each parameter was obtainted by matching and zonation landslide map was obtained. Finallay the resaults of the study shows that 81% of the region marked as high and very high hazard.
