Climbing the crustal ladder: Magma storage-depth evolution during a volcanic flare-up

Very large eruptions (>50 km3) and supereruptions (>450 km3) reveal Earth's capacity to produce and store enormous quantities (>1000 km3) of crystal-poor, eruptible magma in the shallow crust. We explore the interplay between crustal evolution and volcanism during a volcanic flare-up in the Taupo Volcanic Zone (TVZ, New Zealand) using a combination of quartz-feldspar-melt equilibration pressures and time scales of quartz crystallization.
