Abstract

Geophysical survey is a very useful and popular tool used by engineering
geologists to examine landslides. We present a case study from the Kapušany landslide,
Eastern Slovakia, where a broad spectrum of geophysical methods were applied along two
perpendicular profiles in order to compare the ability of the methods to detect as many
structural features of the landslide as possible. The 2D Electrical Resistivity Tomography
inverse model was capable of defining the geological structure of the landslide and defining
the shear zone, however the resolution of the inverse model does not allow us to identify
cracks or other minor features of the landslide. These, however, were well recorded in
the results of Dipole Electromagnetic Imaging and the Self Potential method. In addition
microgravimetry, Gamma-Ray Spectrometry and Soil Radon Emanometry were experimentally
employed to validate the results obtained from electrical methods and afterwards
final geological models, based on the integrated interpretation of all involved methods were
constructed.
