IDL plotting code from NETCDF files generated by Matlab - Generating Probabilities Exceeding Threshold Results
27 May 2016 | Contributor(s):: Peter W Webley
This is the IDL pro files needed to plot the NETCDF outputs from Reza's Matlab code. There is a WORD file that explains each IDL pro file. You will also need the associated PNG files.

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...

17 Jan 2014 | | Contributor(s):: Bettina Martinez-Hackert
This is a first analysis of the crystallinity of the black ash material observed in the column of the Dec 29th eruption of Chaparrastique volcano, El Salvador.

Size of volcanic ash
08 Feb 2011 | | Contributor(s):: William I Rose
Size of ash particles is discussed--ash, lapilli, fine and very fine ash, phi sizes, lognormal distributions and bimodal ones. Patterns of fallout and grain size distributions.
Origin of volcanic ash: Mechanisms for formation
Mechanisms for the formation of volcanic ash are reviewed and discussed, including explosive vesiculation, phreatomagmatic explosions and milling/comminution.
