Among various natural hazards, landslides are the most widespread and damaging. Potentials landslide-prone areas should, therefore, are identified in advance in order to reduce such damage. In this respect, landslide susceptibility assessment can provide valuable information essential for hazard mitigation through proper project planning and implementation. This paper presents a geographic information system (GIS) and based the Analytic Hierarchy Process (AHP) making approach for landslide susceptibility analyses. AHP is a commonly used solution technique for solving any multi-criteria decision making problem. This method is one of the most flexible and easily implemented multi-criteria decision making techniques. It is a theory of measurement concerned with dominance priorities from pair-wise comparison of elements with respect to a common criterion. Multi-criteria analysis is performed to evaluate landslide susceptibility for each data layer, according to appropriately measured and weighted factors. A landslide susceptibility map for each data layer is developed using an algorithm that combines factors in weighted linear combinations. To verify the practicality of the susceptibility map was compared with a landslide inventory map containing 56 active landslide zones. The outcome was that the active landslide zones do not completely fit into the high and very high susceptibility class. But 84% of these landslide zones fall into the high and very high susceptibility zones.
