摘要: Abstract A geophysical investigation was applied to an area, subjected a large slow moving landslide in the region oi Langhe - Piemonte, Italy. The joint application of vertical electrical soundings (VES), resistivity tomography (ERT) and electromagnetic (TDEM) has led detection geo-morphological conditions slope up depth 30–40 m. survey detected existence continuity potential sliding surface, which had previously pointed out by inclinometer measurements. test permitted verification reliability resolution data analysis for landslides, characterised marls clay with low values (below 100 Ohm·m).
