The main objective of this study is landslide Susceptibility mapping in the Shirpanah, by
using of Entropy model and evaluation of this model in the zoning of landslides occurrence
of Shirpanah Mountain and the extent of the influence of each of these five factors on the
occurrence of the landslide. In the survey aerial photographs, satellite imagery, topographic
maps, geological maps and field research to identify the area and were photography from the
occurred landslide. In order to landslide susceptibility Mapping in the area of entropy model
was used in GIS environment. The results show that the distance of the fault, slope,
elevation, lithology and slope, have respectively, the greatest impact of landslides in this
area. The total area of 20 km² (32%) is consist of in high-risk areas and 380 km² (84/48%) in
average-risk zones. This suggests that the potential risk of landslides in the area is high. Also
the results suggest that a 60 percent area landslides in the area in the sensitive areas
identified by the entropy model was located. Therefore, the validity of the proposed model is
verified and Susceptibility maps produced can be used as a reference in the planning.
