FPLUME is a steady-state 1D cross-section averaged eruptive plume model which accounts for plume bent over, entrainment of ambient moisture, effects of water phase changes on the energy budget, particle fallout, particle re-entrainment by turbulent eddies, different empirical parameterizations...

A fluid-dynamic model is developed to numerically simulate the non-equilibrium dynamics of polydisperse gas-particle mixtures forming volcanic plumes. Starting from the three-dimensional N-phase Eulerian transport equations for a mixture of gases and solid particles, we adopt an asymptotic...

Eruption data for ash-cloud model validation
04 Apr 2013 | Contributor(s):: Larry Garver Mastin, Costanza Bonadonna, Arnau Folch, peter webley, barbara stunder, Michael Pavolonis
This is a collection of data, references, and links to data on well-documented eruptions whose observations can be used to validate ash-cloud transport models. Data include, among other things, plume height, duration, erupted volume, satellite observations, numerical wind fields, and grain-size...

Determination of the largest clasts of tephra deposits for the characterization of explosive volcanic eruptions: report of the IAVCEI Commission on Tephra Hazard Modelling
27 Jul 2011 | Contributor(s):: Costanza Bonadonna, simona scollo, Raffaello Cioni, Laura Pioli, Marco Pistolesi
This report summarizes the results of the field workshop of the IAVCEI Commission on Tephra Hazard Modelling that was carried out in Salcedo, Ecuador (January 16-18, 2006) with the main objective of assessing the best way to characterize the largest clasts of tephra deposits. Defining the largest...
