ERT can be used for various problems concerning slope deformations and accompanying landform assemblages. Our study shows that the best results are obtained in sites with high resistivity contrasts in subsurface environment associated with e.g. changes of lithology or ground water conditions. Good results, which significantly extrapolate geomorphic and speleological investigations, were obtained in elevated gravitationally spread ridges with the presence of crevice-type caves. Resistivity soundings in such settings bring a new insight into the internal structure of deeply disrupted mountain ridges. Very promising seems to be also delimitation of bodies of active, water-saturated landslides or lacustrine deposits behind landslide dams.
