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 …

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 …

An increasing number of studies are being presented demonstrating that volcanic glasses
can be heterogeneous at the nanoscale. These nano-heterogeneities can develop both …

Mineral-hosted melt inclusions have become an important source of information on
magmatic processes. As the number of melt inclusion studies increases, so does the need to …

Although gas exsolution is a major driving force behind explosive volcanic eruptions,
viscosity is critical in controlling the escape of bubbles and switching between explosive and …

Aluminosilicate glasses and melts are of paramount importance for geo-and materials
sciences. They include most magmas, and are used to produce a wide variety of everyday …

Degassing dynamics play a crucial role in controlling the explosivity of magma at erupting
volcanoes. Degassing of magmatic water typically involves bubble nucleation and growth …

Magma from Plinian volcanic eruptions contains an extraordinarily large numbers of
bubbles. Nucleation of those bubbles occurs because pressure decreases as magma rises …

Abstract The 2020–21 eruption of La Soufrière, St Vincent began with extrusion of a viscous
lava dome, which was destroyed upon transition to a major explosive phase. Here we …

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