| description | Landslides are one of the leading natural disasters in the Black Sea Region of Türkiye. Trabzon is the province where the most
landslides occurred in the country. Landslide susceptibility maps should be prepared in order to predetermine the areas with high
landslide susceptibility in order to minimize the losses due to landslides. In this study, landslide susceptibility analysis is performed,
and landslide susceptibility maps are produced to reveal the areas with high landslide susceptibility within the boundaries of Akçaabat
and Düzköy districts of Trabzon province using Analytical Hierarchy Process (AHP) and Frequency Ratio (FR) methods. ArcGIS for
Desktop, one of the Geographic Information Systems (GIS) platforms, is used for landslide susceptibility analysis. Geographical data
are obtained from public institutions and open access online sources. The data are spatially organized according to the study area and
purpose by various GIS tools. A total of 13 criteria which are respectively; slope, curvature, lithology, precipitation, aspect,
topographic wetness index (TWI), distance to rivers, distance to highways, distance to fault lines, land use, soil type, elevation and
normalized difference vegetation index (NDVI) for landslide susceptibility are evaluated as effective to cause landslides as a result of
the literature review. Pairwise comparisons are made to determine the importance of the effects of each criterion on landslide formation
and the weights between the criteria by using the AHP method. Then a landslide susceptibility map is produced according to the AHP
method. In addition, a landslide susceptibility map was produced according to the FR method using the landslide inventory records
obtained from responsible institutes of the country. It is noticed that the FR method produced more realistic results than the AHP
method in terms of determining the locations of the landslides observed in the study area when the maps produced by both methods
are compared.
