Incasion, Breakdown

  • Alfred Bögli


Incasion, breakdown, comprises all processes which cause the walls and ceilings of an underground cavity to break down naturally, and also as an exception the passage floor (bumps). In French the terms effondrement, éboulement, affaissement, décollement are used, in German Deckenbruch, Versturz, Einsturz, Höhlenverfall, Ablösung, Bergschlag, etc. The term incasion is derived from the Latin incadere, which means to crash into or to break into; the prefix in points out that the crashing rock falls into a cavity. Incasion is equal to the two other cave forming factors: corrosion and erosion.
