Mt. Vesuvius: Dipolar geoelectric tomography, self-potential survey and magnetotelluric soundings

We present the results of a multi-methodological geophysical study of the Vesuvian area, essentially devoted to define the structural model of the volcanic apparatus, which is the base knowledge to understand the dynamic processes. In particular, 1993-95 we carried out: a dipolar geoelectric tomography along a N-S profile of about 15 km of length, from Pomigliano d'Arco to Trecase, in order to evaluate the resistivity distribution along the profile and down to the depth of about 3 km b.s.l.; a self-potential areal survey consisting of 1250 measurements, distributed over an area of about 170 km2; a magnetotelluric sounding in the Valle dell'Inferno area, which was added to a set of 11 soundings performed in previous surveys
