The 1991 eruption of Mount Pinatubo in the Philippines, classified as VEI 6, cooled global climate by up to 0.7 °C for several years. Papale P., W. Marzocchi (2019).Science, 363/6433, 1275-1276, DOI: 10.1126/science.aaw7201. Eruzioni nel mondo, presentata la prima stima globale delle probabilità Un recente studio…

Figure 1. Location map of the sites discussed in the text. The figure shows the density track of winter storms according to ERA-Interim 1989–2009. Numerical values (number of cyclones/deg2) represent the average spatial density of cyclone centers in the winter season. Only cyclones with a minimum of 1-day duration and…

Three-dimensional simulation of a partial column collapse scenario at Vesuvius. The input conditions of the multiphase flow model are representative of a Sub-Plinian eruption with a mass flow rate of 8 x 10’7 kg/s. Two particle classes of 30 and 500 microns were modeled to represent the ejected pyroclasts. The…

Figura 1. Concentrazione totale di particelle piroclastiche nell’atmosfera (in scala logaritmica). A) Posizione iniziale del volume di magma, prima dell’esplosione. B) Rappresentazione 3D della concentrazione a 380 s dall’inizio del blast. C) Rappresentazione 2D lungo la sezione NordEst, sovrapposta alla mappa a 10 m dal suolo a 380 s. Map…

Figure 7. Results of IMEX_SfloW2D numerical simulations of a pyroclastic avalanche overlapped on the hill-shaded relief of the Etna summit and the boundaries of the 11 February 2014 event. Numerical parameters as follows: (a) μ=0.1, ξ=500; (b) μ=0.2, ξ=500; (c) μ=0.2, ξ=100; (d) μ=0.3, ξ=500; (e) μ=0.4, ξ=500; (f) μ=0.4,…
