Abstract. This paper reports the results of a geoelectrical survey carried out to investigate the Montaguto earth-flow, located in the southern Apennines (Campania Region, southern Italy). The aim of the survey was to reconstruct the geometry of the landslide body, to improve the knowledge on the geological setting and to indirectly test the effectiveness of a drainage system. Although electrical resistivity contrasts in the electrical images were not very pronounced, due to the lithological characteristic of the outcropping lithotypes, it was possible to observe the presence of both lateral and vertical discontinuities that were associated with lithological boundaries, physical variation of the same material and sliding surfaces. The geoelectrical information obtained was provided to the Italian National Civil Protection Department technicians and was considered for the planning of more appropriate actions for the stabilization and safety of the slide.
