It has been 10 years since the ash cloud from the eruption of Eyjafjallajökull caused
unprecedented disruption to air traffic across Europe. During this event, the London Volcanic …

Eruptive column models are powerful tools for investigating the transport of volcanic gas and
ash, reconstructing past explosive eruptions, and simulating future hazards. However, the …

Explosive volcanic eruptions inject hot mixtures of solid particles (tephra) and gasses into
the atmosphere. Entraining ambient air, these mixtures can form plumes rising tens of …

Real-time estimation of eruptive source parameters during explosive volcanic eruptions is a
major challenge in terms of hazard evaluation and risk assessment as these inputs are …

It is increasingly recognized that the gravitational stability of explosive eruption columns is
governed by complex ash-pumice-gas (multiphase) interactions as well as the mechanics of …

Accurate forecasting of volcanic particle (tephra) dispersal and fallout requires a reliable
estimation of key Eruption Source Parameters (ESPs) such as the Mass Eruption Rate (QM) …

When volcanic gases enter the atmosphere, they encounter a drastically different chemical
and physical environment, triggering a range of rapid processes including photochemistry …

Volcanic ash in the atmosphere is a hazard to aviation. To predict which areas of airspace
are most likely to be affected by the presence of ash, Volcanic Ash Advisory Centers …

We have developed an aggregation scheme for use with the Lagrangian atmospheric
transport and dispersion model NAME (Numerical Atmospheric Dispersion modelling …

Turbulent buoyant plumes moving through density stratified environments transport large
volumes of fluid vertically. Eventually, the fluid reaches its neutral buoyancy level at which it …
