Résumé(disponible en anglais seulement)
The nomenclature established by the Working Party for World Landslide Inventory has become the basis for an emerging consensus on landslide classification. This Working Classification encompasses seven mutually exclusive descriptors of the state of activity of the landslide, seven of the distribution of movements and five to describe the style of activity. The velocity of the movements can be described from an open-ended, seven division scale, ranging from extremely slow to extremely rapid. The material displaced may be rock, debris or earth with a range of four qualitatively-estimated water contents. Then there are five types of landslide, falls, flows, slides, spreads and topples. We suggest additions to the Classification, additional states of activity preceding displacements and inclusion of frozen water in the description of water content. Careful documentation of these additions would lead to more comprehensive landslide characterization and better management of landslide risk.
