Abstract

Several geophysical methods, electrical resistivity tomography (ERT), gravimetric prospecting (G), Ground Penetrating Radar (GPR) and seismic methods (S), are commonly applied to characterize karst cave (Beres et al., 2001; Martínez-Moreno et al., 2015; Bermejo et al., 2016; and references therein). In detail, the geophysical approach provides information on cave geometry and subsurface geological structure. Several karst areas have a complex deep system, but the geophysical methods, such as geoelectrical ones, offer partial deep information due to a low-resolution. Therefore, this work would like to introduce a new 2D and 3D geoelectrical approach, that we call "cave-surface" ERT, which define an improvement of the deep resolution comparing to surface ERT. Finally, an application of this new methodology in the karst cave Castello di Lepre (Marsico Nuovo, Basilicata region, Italy) is described.
