Open-vent volcanoes fuelled by depth-integrated magma degassing

M Edmonds, EJ Liu, KV Cashman - Bulletin of Volcanology, 2022 - Springer
Open-vent, persistently degassing volcanoes—such as Stromboli and Etna (Italy), Villarrica

Textural studies of vesicles in volcanic rocks: an integrated methodology

T Shea, BF Houghton, L Gurioli, KV Cashman… - Journal of Volcanology …, 2010 - Elsevier
Vesicles in volcanic rocks are frozen records of degassing processes in magmas. For this
reason, their sizes, spatial arrangements, numbers and shapes can be linked to physical …

Permeability controls on expansion and size distributions of pyroclasts

AC Rust, KV Cashman - Journal of Geophysical Research …, 2011 - Wiley Online Library
We synthesize field and experimental data to evaluate relationships between the textures

Shallow vent architecture during hybrid explosive–effusive activity at Cordón Caulle (Chile, 2011–12): evidence from direct observations and pyroclast textures

CI Schipper, JM Castro, H Tuffen, MR James… - Journal of Volcanology …, 2013 - Elsevier
In June 2011, an eruption of rhyolite magma began at the Puyehue–Cordón Caulle volcanic
complex, southern Chile. By January 2012, explosive activity had declined from sustained …

Direct observation of degassing during decompression of basaltic magma

B Bonechi, M Polacci, F Arzilli, G La Spina… - Science …, 2024 - science.org
Transitions in eruptive style during volcanic eruptions strongly depend on how easily gas

Transition between fragmentation and permeable outgassing of low viscosity magmas

A Namiki, M Manga - Journal of Volcanology and Geothermal Research, 2008 - Elsevier
Explosive volcanic eruption requires that magma fragments into discrete parcels. Silicic
magma can fragment through brittle failure or other processes that depend on the …

The effects of outgassing on the transition between effusive and explosive silicic eruptions

W Degruyter, O Bachmann, A Burgisser… - Earth and Planetary …, 2012 - Elsevier
The eruption style of silicic magmas is affected by the loss of gas (outgassing) during ascent.
We investigate outgassing using a numerical model for one-dimensional, two-phase, steady …
