A suggested method for describing the activity of a landslide

  • UNESCO Working Party On World Landslide Inventory


The activity of a landslide can be described by terms relating to the timing of the landslide, the State of Activity, to which parts of the landslide are moving, the Distribution of Activity, and to how different movements contribute to the overall movement, the Style of Activity.

Proposition pour une méthode de description de l’activité d’un glissement de terrain


On peut décrire l’activité d’un glissement de terain en décrivant l’état de l’activité, la distribution de l’activité et le style de l’activité. L’état de l’activité décrit l’écrit l’évolution temporelle des mouvements. La distribution de l’activité décrit les relations entre les parties du glissement de terrain qui sont en mouvement. Le style de l’activité décrit comment les mouvements différents contribuent au glissement entier.
