Physical data and based geographic information systems based landslide susceptiplity assessment of Vakfikebir (Trabzon) district

It is known that landslides are very common in our country, especially in the Black Sea Region. By examining this issue in detail, it becomes necessary to produce permanent solutions in order to minimize the negative effects on human and life possibilities. In this study, landslide susceptibility analysis of Vakfıkebir (Trabzon) district was carried out. 1: 25.000 scaled geology map of Vakfıkebir and its surroundings was obtained from MTA General Directorate. Due to the excessive and heavy rainfalls in the region, many landslides have occurred on the residual soil soils, especially derived from the highly and completely weathered rocks. Inventory of the study area map landslides, much time has been prepared GoogleEarth prepared by the MTA using benefiting from Turkey's National Landslide Inventory map display options. A landslide susceptibility map based on physical data was produced by using the SINMAP (Stability Index Mapping) mathematical model, using the physical and mechanical test data made on samples taken from the residual soil soils surfaced in the study area. In addition, with the studies carried out, landslide susceptibility maps were produced using the Frequency Ratio (FR) and Entropy Index (EE) methods, which are accepted as probabilistic methods. In these sensitivity maps, five different sensitivity areas were determined as very low sensitivity, low sensitivity, medium sensitivity, high sensitivity and very high sensitivity. The accuracy evaluations and comparisons of the produced landslide susceptibility maps were examined and the estimation evaluations made were examined.
