Conflow 1.0.5
01 Feb 2011 | Offline Tools | Contributor(s): Larry Garver Mastin
Conflow is a user-friendly program that calculates flow properties of magma-gas mixtures through eruptive conduits during steady explosive volcanic eruptions. It also calculates physical and thermodynamic properties of magma-gas-crystal mixtures. The attached zip file installs the program on any...

Confort 15 (Conflow improvement)
20 Jan 2015 | Offline Tools | Contributor(s): Silvia Campagnola, Claudia Romano, Larry G Mastin, Alessandro Vona
We present an updated version of the Conflow model, an open-source numerical model for flow in eruptive conduits during steady-state pyroclastic eruptions (Mastin and Ghiorso, 2000). In the Confort 15 program, several updates were considered:The rheological parameters of the model are...

Eruption data for ash-cloud model validation
04 Apr 2013 | *Data Sets/Collections | 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...
