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

One of the most intriguing and (from the point of view of modeling) poorly understood
aspects of geomaterial mechanics is strain localization. Strain localization is a common …

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 …

Terrestrial volcanic eruptions are the consequence of magmas ascending to the surface of
the Earth. This ascent is driven by buoyancy forces, which are enhanced by bubble …

A major hazard to jet engines posed by volcanic ash is linked to the wetting and spreading
of molten ash droplets on engine component surfaces. Here, using the sessile drop method …

The strength and deformation mode (brittle vs ductile) of rocks is generally related to the
porosity and pressure conditions, with occasional considerations of strain rate. At high …

Gas‐and‐ash explosions at the Santiaguito dome complex, Guatemala, commonly occur
through arcuate fractures, following a 5‐to 6‐min period of inflation observed in long‐period …

There is a rich diversity in lava dome morphology, from blocky domes and lobes to imposing
spine and whaleback structures. The latter extrude via seismically active, gouge-rich conduit …

Shearing of magma during ascent can promote strain localisation near the conduit margins.
Any mechanical and thermal discontinuities associated with such events may alter the …

An emerging elementary particle imaging technique called muography has increasingly
been used to resolve the internal structures of volcanoes with a spatial resolution of less …
