Thermokarst - Wikipedia
Thermokarst is a type of terrain characterised by very irregular surfaces of marshy hollows and small hummocks formed when ice-rich permafrost thaws. The land surface type occurs in Arctic areas, and on a smaller scale in mountainous areas such as the Himalayas and the Swiss Alps.

Thermokarst, land surface configuration that results from the melting of ground ice in a region underlain by permafrost. In areas that have appreciable amounts of ice, when the ice melts and the ground settles unevenly, small pits, mounds, …
What is Thermokarst? - WorldAtlas
2017年9月21日 · A thermokarst refers to the formation of a landscape as a result of the melting of permafrost ground. It is caused by anything that depletes the layer of land vegetation such as natural erosion, deforestation, agriculture, and the construction of buildings.
Thermokarst lakes, drainage, and drained basins
Thermokarst lakes and drained lake basins are widespread in Arctic and sub-Arctic permafrost lowlands with ice-rich sediments.

Thermokarst is, basically, a thermal process that leads to the melting of ground ice and therefore causes subsidence or caving of the soil and the underlying sediments. Thermokarst characterizes only permafrost areas with an appreciable content of ground ice.
