Özet: Landslide susceptibility mapping is of critical importance to identify landslide-prone areas to reduce future landslides, casualties, and infrastructural damages. In this study, the Landslide Susceptibility Map of Samsun (Turkey) was produced. The Slope, elevation, land use, soil, proximity to stream networks and lakes, proximity to fault lines were selected as parameters. All parameters were divided as the sub classes according to their properties. The Frequency Ratio method was applied to determine the relationship between the parameters and the landslide events. Paired comparison matrices were created to determine the weights of the parameters using the Analytical Hierarchy method. The weighted overlay operation was applied to the classified and weighted map data using ArcGIS program. As a result, the Landslide Susceptibility Map was produced as divided to 5 classes.
