Rev. ed. 2016This technical report describes the method used to draw the susceptibility maps for snow avalanches in Norway. In order to cover the entire territory of Norway, a fully-automatic GIS-based solution was developed and applied. The gridded digital elevation model of Norway at 25 meter cell size is the only input dataset. The potential release areas are detected applying a slope angle threshold. The potential propagation zones are delimited coupling a 2D extension of the alpha-beta method with a cone propagation model. In the final product, (1) potential release areas and (2) potential propagation zones are mapped. Finally limitations and issues related to the use of these maps are discussed in the last chapter.
