Different rock properties cause various specific resistivities of rocks. The ability to distinguish between different rock types depends on lithology, intensity of chemical and frost weathering, or mechanical disruptions caused by ravitational slope movements and tectonic processes. Water content and water mineralization are factors with very variable effects on resistivity. The final resistivity model represents a complex value describing the combined effect of all above-mentioned factors. Due to its versatility and relatively easy data processing, electrical resistivity measurements (ERT) can be seen as the leading geophysical method for identifying tectonic features. The method can be used for both (i) large scale surveying of the main fault structures and (ii) detailed investigation of the near-surface manifestations of the fault. Here we present some examples from Central Europe that exhibit typical resistivity images of active faulting.
