| Abstract | The presented study is focused on the summit hydrothermal system of strombolI volcano. This hydrothermal system has already been emphasized by several studies (Finizola et al. 2002, finizola et al. 2003, revil et al. 2004). All these studies attest the presence of an active hydrothermal system. A preferential pathway for up flowing fluids is also brought out, around a structural limit : The upper part of the rina grande sector collapse, forming the crest of the studied area (Figure 1). The dataset designed for the characterization of this system is composed of 13 profiles of self potential (Sp) Measurements, temperature (T) At 30 cm depth, co2 flux and electrical resistivity tomography (Ert) Measurements. In the first section we present the dataset. The second section is dedicated to the ert models and all the added value we can provide for the accuracy of such models. The final section will present preliminary results in fractured porous media, and the outlooks we hope to implement for the characterization of such hydrothermal systems. |
