Indicators and landslide risk maps for France at national scale are computed and presented. Two quantitative approaches are employed, and the results, including the landslide hazard map and landslide risk maps generated from composite indicators for built-up areas and roads, are examined. These documents are intended to be used in the national strategy for landslide risk prevention.
