Abstract

In order to study Vesuvius Volcano (Italy), active traveltime seismic tomography algorithm with the adaptive media parameterization were applied to the TOMOVES (1994 - 1996) experiment dataset. The velocity model shows certain key features that are in a good agreement with the previous studies and geologic and geophysical data: high-velocity anomaly inside the volcano cone, low-velocity anomalies over the volcano flanks and the upwelling of the limestone basement towards East. At the same time our model shows better resolution in the upper 2 km of the crust and reveals a low-velocity anomaly at 2-4 km depth beneath the volcano edifice. The position of this anomaly coincides with the cluster of the volcano earthquakes.
