The performance of the models was comprehensively evaluated using metrics including the Receiver Operating Characteristic (ROC) curve, F1-Score, and overlap rate analysis. The results revealed that the statistics-based FR model Area Under the Curve (AUC) = 0.884, F1-Score = 0.87 significantly outperformed the expert opinion-based AHP model (AUC = 0.699, F1-Score = 0.68) for across all metrics. In the overlap rate analysis, which demonstrates the practical validity of the models, 92.7% of the existing landslide areas fell within the ’High’ and ’Very High’ susceptibility classes on the FR map compared to 73.7% on the AHP map. These findings prove that the FR method is a reliable and precise tool for identifying high-risk areas and for land-use planning in the region.}, number={2}, publisher={Ege Üniversitesi}
