Earthflows on permafrost

Abstract

Earthflows are discussed which are characteristic of various regions where loose sediments overlie permafrost. Their shape and genesis are considered as well as processes generating the earthflows and associated with them. 4 different types of the earthflow are distinguished. It is noted that active land use in the susceptible regions contributes to the process of the formation of earthflows, including big ones which endanger constructions and sometimes destroy them.
