Short summary
We simulate the deformation of Somma-Vesuvius volcano due to some overpressure sources by means of a finite element 3D code. The goal of these simulations is to investigate the influence of topography and structural heterogeneity on ground deformation. The results suggest that they are key factors governing the ground deformation. Our study clearly demonstrate that a better knowledge of deformation patterns can significantly help in the design of an efficient geodetic network.
