Papale (2022).Geoscientific Model Development, 15, 3773–3796, https://doi.org/10.5194/gmd-15-3773-2022, 2022 Abstract Numerical simulations of volcanic processes play a fundamental role in understanding the dynamics of magma storage, ascent, and eruption. The recent extraordinary progress in…

Abstract Volatiles are the fuel and fundamental control for major processes involving magmas and volcanoes. Magmatic volatiles are not just transported by magmas. They do cause, to a large extent, magma transfer from deep…

Schematic illustration of the phenomenological model for paroxysm initiation. (a) Paroxysm initiation starts with the ascent of a LP magma batch from its storage region. LP magma ascent results in bubble (grey rounded symbols) nucleation, vesiculation and closed-system degassing. Arrival of the LP magma at shallow levels is preceded or…

Figure 5. Andesite-dacite mixing result for mesh 3: segregated layers of magmas displayed as contours of mass fraction at time t = 785 s. Garg D., P. Papale (2022). Rapp. Tec. INGV, 441: 128, https://doi.org/10.13127/rpt/441 Abstract GALES is a generalpurpose multiphysics finite element software developed at…

Sampling probability distributions of input parameters (collapsing volume and initial concentration of solid particles) in two sets of simulations performed for Campi Flegrei (see Fig. 10). Values in the color scales represent the sampling probability per cell, where each cell corresponds to one hundredth of the variation range of each…
