Investigation of the rize central district and surroundings in terms of landslide susceptibility

In this study, landslide susceptibility analysis of the Rize central district and surroundings was performed by using statistical analysis methods. Inventory maps of landslides occurred in the region were prepared by field works and using the high resolution satellite image. The data obtained from different sources were evaluated by Geographical Information Systems (GIS) and Remote Sensing (RS) techniques. Landslide susceptibility maps were produced using logistic regression analysis (LRA). On these susceptibility maps, five different susceptibility area were separated. These are as follows; very low, low, medium, high and very high susceptible area. Performance analysis of these maps was carried out by comparing the actual landslides. On susceptibility maps, produced with LRA 70 % of the total area were determined as susceptible, high and very high susceptible areas. According to the results, performance analysis of susceptibility maps showed that these produced maps are suitable for use.
