Comparison between archaeological elevation changes (black arrows) and vertical ground surface displacements for the prolate (red), sphere (blue) and oblate (green) sources in the six reference sites. The actual location of the site corresponds to the position of the paleoenvironmental data. The vertical displacement for the prolate source is reported with contour lines (thick line 1-m iso-deformation, thin line 0.5-m iso-deformation). It is worth noting the areal extent of the contour lines up to the main geological complexes around Somma-Vesuvius: Campi Flegrei volcano to the west, Lattari Mountains to the southeast, Apennine Chain in the Campanian Plain to the northeast.
