VUELCO deliverable 7.5: Guidelines for the best practice of scientific management of volcanic unrest
09 Sep 2015 | Contributor(s): dmitri rouwet
Volcanic eruption forecasting and hazard assessment are multi-disciplinary processes with scientific and social implications. Our limited knowledge and the randomness of the processes behind a volcanic eruption yields the need of quantifying uncertainties on volcano dynamics. With deterministic...

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...
Underwater volcano disaster - an Oxford Sparks Animation
19 Mar 2014 | Contributor(s): David Pyle
A short (2 minute) animation of a subduction zone and volcano, introducing the processes involved in subduction, melting and volcanism.This animation can be used as a stand alone item, or in a classroom. We have developed some class activities around an exercise in volcano monitoring at an...

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...

This series of two lectures summarizes the sequence of events asssociated with the 1980-86 eruptions of Mount St Helens, Washington State, USA. It is intended as a refresher for students and researchers.Lipman, Peter W., and Mullineaux, Donal R. (eds.), 1981, The 1980 Eruptions of Mount St....
GeoProMT v1.0 - Geospatial Project Management Tool
26 Apr 2011 | *Data Sets/Collections | Contributor(s): Chris S Renschler, Fernando Rios, Graham S Hayes, Jorge Valentin Bajo, Thomas W. Slomka, Michael Sheridan
The Geospatial Project Management Tool (GeoProMT) is a web-based tool for management of shared geo-spatial and multi-temporal data such as GIS data and remotely sensed images. Integral to the GeoProMT framework is role-based access control (RBAC), where data access permissions and data users are...
