Fig. 5: Conduit dynamics of Antuco volcano.
From: Long-term volcano evolution controlled by lateral collapse at Antuco volcano, southern Andes, Chile
Evolution of (a) pressure, (b) temperature, (c) exsolved gas volume fraction, (d) dissolved volatile content, (e) mixture velocity, (f) mixture viscosity, (g) mass eruption rate (MER), and (h) Deborah number. The numerical results are retrieved from the conduit model for the pre- (blue line) and early post-collapse (red lines) situations of Antuco volcano, considering the pre-collapse composition is basaltic and the early post-collapse is andesitic. Only the upper 5 km of the conduit are shown for the basalt simulation which ascends from 15 km (Supplementary Fig. 2). The red dashed line corresponds to the unloaded edifice with a conduit 900 m shorter. That scenario is the only one able to produce an explosive eruption for the given conditions and shows a comparatively higher mass flow rate.
