<idAbs>On distingue trois types d'instabilités : Les glissements superficiels
Dans les pentes où la couche superficielle se trouve en état d'équilibre limite, une dégradation temporaire de la qualité du sol, par saturation lors de pluies notamment, entraîne soit des écoulements sans limites nettes (solifluxion), soit des glissements avec des arrachements superficiels mettant à nu la surface.
Les glissements profonds
Les glissements profonds sont caractérisés par la présence de niches d'arrachement, généralement multiples, bien marquées, avec un déplacement d'une masse de matériaux meubles ou rocheux le long d'une ou de plusieurs surfaces de glissement situées en profondeur et de moindre résistance.
Les éboulements
Ce phénomène s'observe généralement dans les falaises d'alluvion ancienne ou de moraine limoneuse à cailloux très compacte.
Progressivement, dans un processus lent, les zones d'éboulement se couchent et peuvent devenir des glissements superficiels avant de se stabiliser.</idAbs>
