This study evaluated the applicability of GLM and GAM models in the establishment of landslide susceptibility zoning guidelines, and found that the GAM model has a slight advantage over the GLM model in susceptibility prediction capacity. The resulting zoning areas for low, moderate, high, and very high susceptibility were very similar for both the GLM and GAM models.
Landslide hazard is usually incorporated into land-use planning as susceptibility zoning. Multiple-variable models have been widely used for susceptibility zoning due to their advantage to use different performance techniques to improve their prediction capacity. In Chile, the incorporation of landslide hazard into land-use planning instruments lacks a frame of reference that defines the susceptibility zoning and potential methodologies to be used. To overcome this lack of reference, this study assessed the applicability of Generalized Linear Model (GLM) and Generalized Additive Model (GAM) models in the establishment of susceptibility zoning guidelines. The application of both models identified the areas-prone to landslides in enough detail for a scale k-fold cross-validation, which indicated a slight advantage of the GAM model over the GLM model in susceptibility prediction capacity. The resulting zoning areas for low, moderate, high and very high susceptibility were very similar for the GLM and GAM models.
