- Аннотация: Recently the intensification of cryogenic processes at high rate is widespread in Russian cryolithozone. Landslides in permafrost area are characterised by frozen bottom of sliding and known as thaw slumps or mudslides. Landslide body consists of frozen soils, which thaws and forms thermo cirques and depressions. Long warm summers and snowy winters of last decade trigger cryogenic landslides over Siberia. The situation with existing linear infrastructure (roads, railways and pipelines) is changing due to permafrost thawing that has not been taken into account during design 5-30 years ago. Apart from deformations to infrastructure cryogenic landslides provoke gas release from permafrost, and disturbance of lands (tundra & taiga) for rendering. Diversity of landslides in permafrost area and 9 study cases are presented in this paper. The mitigation measures are not applicable for cryogenic landslides at high rates. There is a call for innovation solutions in this area.
