ASHEE
14 Aug 2015 | Contributor(s): Matteo Cerminara, Tomaso Esposti Ongaro
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...

Pyroclastic density currents and local topography as seen with the conveyer model
15 Apr 2014 | Contributor(s): Domenico M. Doronzo
Pyroclastic density currents (PDCs) are multiphase flows generated during explosive volcanic eruptions, and they move down the volcano, and over the surrounding topography. The flow-topography interaction can play a fundamental role in the sedimentary processes, and in the resulting deposit...

Large Scale Experiments on Volcanic Processes (EOS)
19 Jul 2011 | Contributor(s): Greg A Valentine
Some of the least understood and most hazardous geologic processes involve complex multiphase flows, particularly those related to explosive volcanic eruptions. These phenomena inherently involve a wide range of characteristic length and time scales, as well as processes that are coupled across...

Mapping a 49 year old eruption of a basaltic cone: Pacaya Guatemala
27 Apr 2011 | Presentations | Contributor(s): William I Rose
This presentation summarizes the 50 year eruption and the 3 dimensional map produced. The map, prepared as part of an MS thesis by Ruben Otoniel Matias Gomez, is under review as a Map and Chart Series publication by the GSA. The lecture summarizes the situation at Pacaya, and uses Matias' map as...

eject model
01 Feb 2011 | Offline Tools | Contributor(s): Larry Garver Mastin
Eject is a user-friendly model that calculates the trajectories of blocks that are ballistically ejected from volcanic craters. It has also been used to calculate ballistic trajectories of other objects in other other settings, including missiles and bullets.Details are at:The attached zip...
