Avalanche qui s'écoule sur une pente ouverte, un versant.

CONT

[...] on classe les avalanches selon leur mode d'écoulement : avalanches coulantes, en aérosol ou mixtes. [...] on peut par ailleurs préciser la forme de l'écoulement imposée par la zone de transit : s'il est confiné, on parlera d'avalanche de couloir, et s'il a lieu sur une pente ouverte, on parlera d'avalanche de versant.
