The thermal plumbing system of Stromboli volcano, Aeolian Islands (Italy) inferred from electrical conductivity and induced polarization tomography

International audienceStromboli Island is located in the northernmost of the Aeolian archipelago in the Southern Tyrrhenian Sea, Italy (Figure 1). The formation of the Aeolian Islands is related to the subduction of the African plate below the Eurasian plate (Barberi et al., 1974; Keller et al., 1993). Stromboli itself rises from a depth of 2,000 m below sea level to an elevation of 924 m a.s.l. (meters above sea level, see Romagnoli et al., 2009). The emerged part of the volcano developed during the last 100 ka (Rosi, 1980). Stromboli is a permanently active and fairly accessible stratovolcano. It is considered a key natural laboratory for geophysical investigations aimed at better understanding its internal structure and structural control of its hydrothermal activity
