Gis-based landslide susceptibility mapping by analytical hierarchy process: a case study, burdur province

The creation of landslide susceptibility maps is a critical step in helping organizers, local authorities, and policy makers with disaster planning. As such, the reliability of these landslide susceptibility maps is essential for decreasing loss of life and property. Increasing populations and settlements in sloped areas have generally enhanced the effect of landslides. In this study, a geographic information system and analytical hierarchy process were used to determine landslide susceptibility zones in Burdur province. For this purpose, ten parameters; distance to fault, wetness index, slope aspect, distance to stream, rainfall, distance to road, curvature, land cover, slope gradient and lithology were selected as conditioning factors associated with active landslides. The results of this study indicate that 11.63% of the investigation area has a high susceptibility and 1.57% has a very high susceptibility. The findings of this study are important for long-term land use planning, emergency decisions, minimization of potential landslide hazards, and saving lives.
