Outer Western Carpathians, gravitational disintegration, fissure caves, electrical resistivity tomography

Fissure caves as well as other subsurface dislocations can represent initial forms of the gravi-tational disintegration of rock massif ranging from shallow to deep-seated (>40 m) gravitational slope deformations. Presence of pseudokarst forms, such as crevice-type caves, trenches, escarpments, tension cracks or sinkhole-type depressions is frequent in the massifs of the Outer Western Carpathians which are formed by anisotropic flysch rock. Detailed research of these landforms can significantly contribute to understanding to the processes transforming a relief of the medium-high mountains in the Carpathian flysch belt. Method of electrical resistivity tomography (ERT) based on various resistivity values of particular subsurface structures offers a non-invasive way to display the situation beneath the surface.
