Abstract

The paper is presenting assessment of cryogenic landsliding hazard based on differentiation of landscapes in Central Yamal. Analysis of a landslide pattern shows that all modern cryogenic landslides are located on concave slopes, representing ancient landslide-affected area. Modern landsliding impact increases from low to high geomorphic levels. Landscape complexes are associated into five groups according to predicted cryogenic landsliding hazard degree. Grouping of landscape complexes is based on (1) differentiation of landscape conditions more or less favourable for cryogenic landsliding and (2) the latest cryogenic landslide occurrence. Landslide distribution within a landscape unit determines its sensitivity to landslide re-occurrence, the larger the area of disturbance by modern landsliding the more sensitive is a landscape complex. At the same time, directly disturbed by the latest landslides areas within a landscape unit are considered non-hazardous because the re-occurrence of cryogenic landsliding on such locations in coming centuries is mostly improbable.
