GIS-Based Landslide Susceptibility Mapping Using Frequency Ratio and AHP Methods

Abstract

In this study, the Landslide Susceptibility Map of Samsun province was produced. Slope classes, altitude classes, land use classes, soil classes, proximity to river networks classes and proximity to fault lines classes were used during the study. The Frequency Ratio method was applied to determine the relationship between the attribute classes of the parameters and the landslide events. Paired comparison matrices were created to determine the weights of the parameters and the Analytical Hierarchy method was applied. Weighted Overlay operation was applied to the classified and weighted map data using ArcMap 10.7 program. As a result of the process, the data were divided into 5 classes and the Landslide Susceptibility Map was produced.
