Abstract
The rate of movement of a landslide can range from extremely slow, less than 16 mm/year or 0.5×10−6 mm/second, to extremely rapid, over 5 m/second. Five intermediate classes cover two orders of magnitude of velocity each. The velocity of a landslide can be correlated with the damage it may cause.
Résumé
La vitesse d'un mouvement de terrain peut varier entre une valeur extrêmement lente, inférieure à 16 mm/an, soit 0.5·10−6 mm/s, et une valeur extrêmement rapide, supérieure à 5 m/s. Cinq classes intermédiaires de vitesse sont proposées, couvrant chacune deux puissances de 10. On peut tenter de corréler la vitesse d'un mouvement de terrain aux dommages causés par celui-ci.
