Abstract	The case study presents GIS-aided statistically and physically based landslide susceptibility mapping in the landslide-prone Avutmus district of Sebinkarahisar (Giresun, Turkey). Field investigations, analysis of geological data and laboratory tests suggested that two important factors have acted together to cause sliding: ground water pressures and toe erosion. Frequency ratio (FR) and stability index mapping (SINMAP) were used to create the landslide susceptibility maps based on a landslide inventory; distance from drainage systems, faults and roads; slope angle and aspect; topographic elevation and topographical wetness index; and vegetation cover. Validation of the models indicated high quality susceptibility maps with the more realistic results were obtained from the statistically based FR model.L’étude de cas présente une cartographie de sensibilité aux glissements de terrain basée sur une approche physique et statistique, avec le support d’un SIG, cartographie réalisée dans le district d’Avutmus sujet aux glissements, région de Sebinkarahisar (Giresun, Turquie). Les travaux de terrain, les analyses de données géologiques et les essais de laboratoire ont fait apparaître deux facteurs importants agissant conjointement, à l’origine des glissements: les pressions d’eau du sol et l’érosion de pied de versant. Les indices FR fréquence des événements) et SINMAP (indice de stabilité) ont été utilisés pour réaliser les cartes de sensibilité aux glissements, prenant appui sur un inventaire des glissements, la distance aux axes de drainage, aux failles et aux routes, la pente et la morphologie des terrains, la position topographique, l’indice d’humidité, la couverture végétale. La validation des modèles permet de souligner la qualité de ces cartes de sensibilité, les résultats les plus réalistes étant obtenus à partir du modèle des fréquences d’événements qui s’appuie sur une approche statistique.
