The 3-D structure of the Somma-Vesuvius volcanic complex (Italy) inferred from new and historic gravimetric data
Abstract Existing 3-D density models of the Somma-Vesuvius volcanic complex (SVVC), Italy, largely disagree. Despite the scientific and socioeconomic importance of Vesuvius, there is no reliable 3-D density model of the SVVC. A considerable uncertainty prevails concerning the presence (or absence) o...
