Volcanic eruptions are driven by bubbles that form when volatile species exsolve from
magma. The conditions under which bubbles form depend mainly on magma composition …

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 …

Pumice rafts that arrived at the Nansei Islands, Japan, provided a unique opportunity to
investigate the Fukutoku‐Oka‐no‐Ba (FOB) eruption of August 2021. Despite drifting for 2 …

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

The Havre 2012 deep-sea rhyolite eruption went unobserved and was initially recognised
from a massive pumice raft at the sea surface. Havre pumices are predominantly white or …

Traditionally depicted as homogeneous materials, manmade and volcanic glasses are often
subjected to nanostructuration during demixing and crystallization of their parental melt …

Nanometer-sized crystals (nanolites) play an important role in controlling eruptions by
affecting the viscosity of magmas and inducing bubble nucleation. We present detailed …
