, 2021 International audienceWe address, through quantitative analysis of results from independent studies, the control of the discharge rate of explosive volcanic eruptions on the runout distance of highly hazardous pyroclastic density currents.

A numerical investigation of constant-volume non-Boussinesq density currents [PDF]
, 2010 The time-dependent behaviour of non-Boussinesq high-Reynolds-number density currents of density ρc, released from a lock of height h₀ and length x₀ into a ambient of height H and density ρₐ, is considered. We use two dimensional Navier-Stokes simulations

Behaviours of pyroclastic and analogue materials, in dry and wet environments, for use in experimental modelling of pyroclastic density currents [PDF]
Modelling pyroclastic density currents (PDCs) is a challenging yet essential element of hazard assessment. PDCs are unpredictable and internal processes are often difficult to measure directly.

Explaining the origin of deposit-derived pyroclastic density currents
Bulletin of VolcanologyAbstract Pyroclastic density currents (PDCs) generated by the collapse of incandescent volcanic deposits represent a widespread but poorly understood hazard at active volcanoes. Their dynamics remain less constrained than those of dome- or column-collapse PDCs.

Pyroclastic density currents (PDCs) are complex, multiphase systems where density strati cation controls the ows' mixing, deposition, and runout, presenting signi cant challenges in hazard forecasting.

, 2011 The interaction between pyroclastic density currents and buildings is investigated by means of numerical simulation and large-scale experiments. Numerical simulation is performed with the Euler-Lagrange approach using a two-way coupling between gas and ...

Turbulent particle-gas feedback exacerbates the hazard impacts of pyroclastic density currents [PDF]
Causing one-third of all volcanic fatalities, pyroclastic density currents create destruction far beyond our current scientific explanation. Opportunities to interrogate the mechanisms behind this hazard have long been desired, but pyroclastic density ...
