Production of landslide susceptibility map of Samsun (Turkey) city center by using frequency ratio method
MetadataShow full item record
Due to the increased need for housing, Samsun province center had been quickly opened for construction in the last 25 years; because of the rapid population growth, construction facilities have progressed towards the southern hillside of the city. Large amount of landslides had been observed and classified in this region by the relevant institutions. To prevent life and property losses, it is required to evaluate past landslides and thus, to determine the probable landslide areas in the construction regions. Therefore, this study aims to create a landslide susceptibility map of Samsun province center. Frequency ratio method which is widely used in the literature has been used to create the landslide susceptibility map. Some characteristic properties of the region such as the geological formation, altitude, slope, aspect, curvature, plan and profile curvature, distance from roads and streams have been considered for the landslide susceptibility evaluation.
