Landslide Susceptibility Analysis with AHP and FUCOM; a case Study of Taşova

Abstract

Various studies are carried out in order to minimize the loss of life and property that may occur after a disaster. One of these studies is disaster risk maps. In order to prepare disaster risk maps, first of all, the criteria affecting them according to the type of disaster should be determined well. Multi-Criteria Decision Making Methods (MCDM) and spatial analyzes are needed as it will be difficult to evaluate more than one criterion alone. MCDM methods help both to weight criteria and to rank among alternatives. The criteria determined for disaster risk maps are weighted with the help of criterion weighting methods, so that the analysis is performed according to these weights and the most optimum result is obtained. In this study, two different Landslide Susceptibility Maps were obtained for Taşova district of Amasya province by using Analytical Hierarchy Process (AHP) and Full Consistency Method (FUCOM). Twelve criteria were determined for map production and raster data was created by performing various spatial analyzes for these criteria. Two different landslide susceptibility maps were obtained by giving criterion weights to the generated raster data.
