Hydrothermal alteration can result in pore pressurization and volcano instability
The collapse of a volcanic flank can be destructive and deadly. Hydrothermal alteration is
common to volcanoes worldwide and is thought to promote volcano instability by decreasing …

Permeability and porosity relationships of edifice-forming andesites: a combined field and laboratory study
Permeability of the edifice is one of the key parameters governing eruptive style, magnitude,
and frequency of active stratovolcanoes. This study presents a suite of density and …

Alteration‐induced volcano instability at la Soufrière de Guadeloupe (eastern Caribbean)
Volcanoes are unstable structures that deform laterally and frequently experience mass
wasting events. Hydrothermal alteration is often invoked as a mechanism that contributes …

Hydrothermal alteration of andesitic lava domes can lead to explosive volcanic behaviour
Dome-forming volcanoes are among the most hazardous volcanoes on Earth. Magmatic
outgassing can be hindered if the permeability of a lava dome is reduced, promoting pore …
