One of the biggest challenges in volcanic hazard assessment is to understand how and why
eruptive style changes within the same eruptive period or even from one eruption to the next …

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

Microcracks can affect the mechanical properties of rocks, such as their stiffness and
strength. To provide a link between the microstructural parameters and the mechanical …

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

Volcanic reservoirs are widely distributed in more than 40 basins in 13 countries and have
become an important target for oil and gas exploration. The study of volcanic reservoirs is …

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 …

Pore connectivity is a measure of the fraction of pore space (vesicles, voids or cracks) in a
material that is interconnected on the system length scale. Pore connectivity is …

The connectivity of rocks' porous structure and the presence of fractures influence the
transfer of fluids in the Earth's crust. Here, we employed laboratory experiments to measure …

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 …
