7 7 avalanches affected not only the villages but also the forest. Single landslides were reported. 4 4 The scope of the service request EMSN-073 is to assess the risk of soil erosion and landslides in the post-disaster phase in wooden areas due to the storm event. Further, the damage on wooden areas with regard to loss of forest masses was assessed. Map Production ! The present map shows the landslide risk assessment in the Eastern French Pyrenees close ! Vinça to the Spanish border. The landslide risk classes have been derived by using a multi-criteria evaluation approach considering factors predictive of landslide occurrence. Six evidential layers including slope, aspect, land use/land cover, lithology, distance to rivers and distance La Llorda to roads were integrated into the model. Each factor was weighted with respect to its relative ! ! importance, which was evaluated based on a landslide inventory. The model has an efficiency of classification of 77% and an efficiency of prediction of 75%. The geometric accuracy is related to the respective accuracy of the input data used for the analysis.
