Authors: Skrylnik G. P., Sorokin P. C.

An external shape and internal composition of polar landscapes are created as a whole by permafrost (continuous, faltering with taliks and island). In some cases, under unfavorable conditions, its own destructive influences on landscapes are strengthened by endodynamic risks (first of all, by seismicity flashes from 1 to 2 points).
