This work presents a method for preparing landslide here susceptibility maps based on an analysis between past movements and predisposing factors.The proposed methodology for determining susceptibility is an adaptation of the matrix method in the territory of the city of Al Hoceima (Northern Morocco).The data needed to evaluate vulnerability has based on the landslide inventory and the available cartographic documents.These data were prepared and integrated into a GIS.This phase of the data preparation has followed by assessment and susceptibility mapping.

The obtained map was validated and compared with an independent landslide dataset than the one used to develop the model.The results of the ROC (receiver operating characteristic) curve demonstrate the good predictive ability (AUC = product 0.94).We can deduce that the map correlates well with the existing terrain conditions.The successfully validated prediction will enable decision-makers to offer handy information for infrastructure construction and urban planning in the future or other areas with similar situations.
