Fig. 2: Comparison of the numerical solutions for the reference and excess volatile simulations.
From: Role of volatiles in highly explosive basaltic eruptions
Evolution of (a) pressure, (b) exsolved gas volume fraction, (c) mixture velocity, (d) mixture viscosity, (e) dissolved volatile content, (f) temperature, (g) total crystal content and (h) mass eruption rate (MER) along the conduit obtained for the Etna 122 BCE reference case (blue solid lines) and for the excess H2O (green and red solid lines) and CO2 (cyan and magenta dashed lines) case. Crystal content indicates the sum of phenocrysts and microlites content, where the phenocryst content is assumed constant throughout the conduit (equal to the initial crystal content), and only microlites are crystallising during ascent.
