Definition

A landslide is the gravitational downslope movement of solids on natural or artificial slopes. The solids are geotechnical materials that can contain water, ice, and air; however the solids are volumetrically dominant over the transport medium (water, ice, and air).

Landslides have been classified based on the movement types (falls, topples, slides, spreads, flows, and complex) and the material involved (bedrock, debris, earth) (Varnes 1978). This classification is broadly accepted although engineering properties of materials (rock, clay, mud, silt, sand, gravel, boulders, debris, peat, and ice) rather than the division into debris and earth are today used, and the term complex is not further recommended, while the term slope deformation is introduced as a movement type (Fig. 1) (Hungr et al. 2014). Therefore, ice is today reconsidered as a possible material. In contrast snow is considered only in Scandinavialine considered as a material in landslide science and snow avalanche...
