PDC invasion hazard maps based on the areal size distributions and vent opening probability maps of Bevilacqua et al. (2017). Contours and colours indicate the mean percentage probability of PDC invasion conditional on the occurrence of an explosive event a originating inland in the western sector, b originating inland in…

Earth Sci., https://doi.org/10.3389/feart.2021.760773 Abstract The dynamics of magma is often studied through 2D numerical simulations because 3D simulations are usually complex and…

Fig. 3B In the uppermost part of the section, the pumice lapilli deposit inversely grades into a c. 50 cm-thick bed made of decimeter-sized, dark brown to reddish pumice bombs (Fig. 3b). Lithic fragments are present but scarce along the entire sequence and are mainly represented by red-oxidized clasts and…

a) Lateral view of an advancing experimental pyroclastic surge at the eruption simulator PELE.b)Schematic sketch of the internal flow structure shown in Fig. 1a. This illustrates the longitudinal subdivision of the gravity current into the frontal head and trailing body regions; and the vertical structure of the gravity current where…
