Effect of the settling velocity distribution of the pyroclastic particles on the probability maps for a deposit load equal to 300 kg/m2. The area enclosed within the 5 % probability contour is 1232, 1356, 1319 and 972 km2, respectively, for the distribution VSET-1990, VSET-79, VSET-1631 and VSET-2008. In the background are reported the “Red Zone” (hazard from pyroclastic flows and lahars) and the “Yellow Zone” (hazard from ash fallout) of the actual Emergency Plan of Vesuvius (DPC 2015; Regione Campania 2015)
