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 …

Magma reservoirs play a key role in controlling numerous processes in planetary evolution,
including igneous differentiation and degassing, crustal construction, and volcanism. For …

The viscosity of magma exerts control on all aspects of its migration through the crust to
eruption. This was particularly true for the 2021 eruption of Cumbre Vieja (La Palma), which …

Magma fragmentation is the breakup of a continuous volume of molten rock into discrete
pieces, called pyroclasts. Because magma contains bubbles of compressible magmatic …

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 …

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 …

A long-standing challenge in volcanology is to explain why explosive eruptions of silicic
magma give way to lava. A widely cited idea is that the explosive-to-effusive transition …

Volcanic rocks and magma display a wide range of porosity and vesicle size, a result of their
complex genesis. While the role of porosity is known to exert a fundamental control on …

Explosivity in erupting volcanoes is controlled by the degassing dynamics and the viscosity
of the ascending magma in the conduit. Magma crystallisation enhances both …

The scientific investigation of magma fragmentation and the development of experiments to
constrain and quantify its mechanisms, dynamics, efficiency and products was ushered in …
