Fig. 12
Effect of the terminal settling velocity on the hazard maps (500 kg/m2). Contour lines represent different probabilities of loading greater than the threshold 500 kg/m2. Input parameters as for Fig. 11. Maximum extension is obtained for particles with settling velocity of 6 m/s (1,831 km2). 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)
