Response of a bubble bearing viscoelastic fluid to rapid decompression: Implications for explosive volcanic eruptions
We conducted rapid decompression experiments using bubble-bearing viscoelastic fluid in a vertical shock tube. We varied vesicularity / and pressure difference between the inside Pg and the outside Po of the bubbles, DP=Pg Po, to understand the behavior of bubbly-magmas under rapid decompression. We find that the potential energy, which depends on the initial vesicularity /, Pg, and Po, determi...
متن کاملMagma decompression rates during explosive eruptions of Kīlauea volcano, Hawaii, recorded by melt embayments
The decompression rate of magma as it ascends during volcanic eruptions is an important but poorly constrained parameter that controls many of the processes that influence eruptive behavior. In this study, we quantify decompression rates for basaltic magmas using volatile diffusion in olivine-hosted melt tubes (embayments) for three contrasting eruptions of Kīlauea volcano, Hawaii. Incomplete e...
متن کاملPhase equilibria trigger for explosive volcanic eruptions
[1] A mechanism for explosive volcanic eruptions based on multicomponent phase equilibria modelling of four explosive volcanic systems is proposed. In each system, either isochoric or isobaric crystallization, where either crystals or crystals and exsolved fluid are chemically fractionated from melt, leads inevitably to near-solidus dynamical instability culminating in violent explosive eruptio...
متن کاملUnsteady high‐pressure flow experiments with applications to explosive volcanic eruptions
[1] Motivated by the hypothesis that volcanic blasts can have supersonic regions, we investigate the role of unsteady flow in jets from a high‐pressure finite reservoir. We examine the processes for formation of far‐field features, such as Mach disk shocks, by using a shock tube facility and numerical experiments to investigate phenomena to previously unobtained pressure ratios of 250:1. The Ma...
