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 …

When considering the rheology of a suspension the fundamental physical aspect to be
quantified is the redistribution of strain between the deformable matrix fraction of the …

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 …

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 …

The reliable assessment of volcanic unrest must rest on an understanding of the rocks that
form the edifice. It is their microstructure that dictates their physical properties and …

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 …

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 …

Volcanic eruptions are regulated by the rheology of magmas and their ability to degas. Both
detail the evolution of stresses within ascending subvolcanic magma. But as magma is …

The ease at which exsolving volatiles can migrate though magma and outgas influences the
explosivity of a volcanic eruption. Volcanic rocks often contain discrete discontinuities …
