The microstructure and mineralogy of volcanic rocks is varied and complex, and their
mechanical behaviour is similarly varied and complex. This review summarises recent …

More than 800 million people live in proximity to active volcanoes and could be directly
impacted by potential eruptions. Mitigation of future volcanic hazards requires adequate …

The accuracy of elastic analytical solutions and numerical models, widely used in
volcanology to interpret surface ground deformation, depends heavily on the Young's …

Extension fractures in volcanic systems exist on all scales, from microscopic fractures to
large fissures. They play a fundamental role in the movement of fluids and distribution of …

Volcanoes are unstable structures that deform laterally and frequently experience mass
wasting events. Hydrothermal alteration is often invoked as a mechanism that contributes …

Hydrothermal fluids can alter the chemical and physical properties of the materials through
which they pass and can therefore modify the efficiency of fluid circulation. The role of …

Our multidisciplinary study aims to better understand the permeability of active volcanic
hydrothermal systems, a vital prerequisite for modelling and understanding their 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 …

Volcano slope instability manifests in many forms, ranging from steady state to punctuated
movement, or shallow erosion to deep-seated spreading. The interplay of gravity, magmatic …

The failure mode of lava—dilatant or compactant—depends on the physical attributes of the
lava, primarily the porosity and pore size, and the conditions under which it deforms. The …
