Any movement affecting a massif is recorded by karst.
Inside the caves, speleothems allow the observation and datation of millimetric movements. Introduction Karstic underground phenomenons settle according to climatic, hydrologic tectonic and lithologic conditions. A karst system is created by the action of agressive water on limestone. Parts of a karstic aquifer flow inside fractures that they widen, organising a drain system. Usually the fractures belong to families whose directions depend on the stress conditions affecting the massif at the birth time ot the karstic system.
