Matlab Codes for Volcanology - Magma Density
13 Aug 2013 | Contributor(s): Tom D Pering
A simple Matlab function for calculating the density of the magma. It is based on the method of Bottinga & Weill (1970) - Densities of silicate systems calculated from partial molar volumes of oxide components. American Journal of Science 269, pp. 169-182It requires the...

Normalising datasets in Matlab
13 Aug 2013 | Contributor(s): Tom D Pering
A very brief and simple Matlab function for normalising a dataset. I have often wondered why Matlab doesn't include this in the main package, so here is a simple code to achieve this.

Preliminary results of satellite and model blending
09 Aug 2013 | Contributor(s): Michael Pavolonis
The objective satellite analysis techniques of Pavolonis et al. and ash probability maps generated from PUFF simulations were combined to produce a better estimate of the horizontal position of the Eyjafjallajokull ash cloud over Europe in regions with mid to high level meteorological cloud...

Matlab Codes for Volcanology - Stokes Rise Calculations for Bubbles
09 Aug 2013 | Contributor(s): Tom D Pering
A series of Matlab codes for the determination of the rise speed of stokes bubbles at a single point (i.e. at a given depth and set radius) and over a range of depths. The aim of these files is to allow the calculation of rise speed given the overall bubble composition and the proportions or mass...

Deep Magmatic Unrest: ground uplift and magma rise at Uturuncu volcano
07 Aug 2013 | Contributor(s): James Hickey, Jo Gottsmann, Rodrigo del Potro
Uturuncu volcano in southern Bolivia has been steadily inflating since at least 1965, and combined with shallow seismicity and near-summit active fumaroles represents a volcanic system showing significant signs of unrest. This study focuses on the mechanism driving the 70 km wide region of ground...

Experimental approach to constrain phreatic eruption processes on White Island, New Zealand (IAVCEI 2013 poster presentation)
06 Aug 2013 | Contributor(s): Klaus Mayer, Betty Scheu, Yan Lavallee, Ben Kennedy, H. Albert Gilg, Michael Heap, Mark Letham, Cristian Montanaro, Laura Jacquemard, Noemie Pernin, Donald D. Dingwell
White Island is New Zealand's most active volcano and primarily characterised by phreatic and phreatomagmatic eruptions. A phreatic eruption on August 2nd, 2012 ended an eleven year quiescence. More than 100 years ofintense hydrothermal activity from magmatic fluids and groundwater has created a...

What good are (PDC) models?
31 Jul 2013 | Contributor(s): Tomaso Esposti Ongaro
This slides have been presented to the W06 workshop on "Benchmarking volcano models" at IAVCEI 2013 (Kagoshima, Japan). The presentation introduces a hierarchy of fluid dynamics models for pyroclastic density currents (PDC) and the problem of estimating their related uncertainties. A validation...
