Catastrophic, caldera-forming explosive eruptions generate hazardous ash fall, pyroclastic
density currents and, in some cases, tsunamis, yet their dynamics are still poorly understood …

Abstract The Minoan eruption of Santorini is one of the largest Holocene volcanic events
and produced several cubic kilometers of pyroclastic flows emplaced on the submerged …

The dynamics of geophysical dilute turbulent gas‐particles mixtures depends to a large
extent on particle concentration, which in turn depends predominantly on the particle settling …

Explosive volcanic eruptions can inject sulfur dioxide (SO2) into the stratosphere to form
aerosol particles that modify Earth's radiation balance and drive surface cooling. Eruptions …

Volcanic eruption columns typically have unsteady source conditions, where mass and heat
fluxes from the vent evolve or fluctuate on time scales from seconds to hours. However …

A multiphase fluid dynamic model is used to explore the effects of entrainment of granular
debris into sustained volcanic jets such as those which produce sub-Plinian to Plinian …

We estimated geometric plume heights for the daytime eruptions of La Soufrière in April
2021 using visible red band geostationary side views and geostationary–polar orbiter stereo …

For decades, scaled analog experiments have improved the understanding of a broad range
of multiphase volcanological processes in controlled laboratory environments. Successfully …

Numerical modelling of tephra fallout is a fast-developing research area in volcanology.
Several models are currently available both to forecast the dispersion of volcanic particles in …

Explosive eruptions expel volcanic gases and particles at high pressures and velocities.
Within this multiphase fluid, small ash particles affect the flow dynamics, impacting mixing …
