Magma ascent rates in explosive eruptions: Constraints from H2O diffusion in melt inclusions

MCS Humphreys, T Menand, JD Blundy… - Earth and Planetary …, 2008 - Elsevier
The pre-fragmentation velocity of magma ascending during explosive volcanic eruptions
remains difficult to quantify. Here we present a new technique for using syn-eruptive volatile …

On the dynamics of volcanic columns: A comparison of field data with a new model of negatively buoyant jets

G Carazzo, E Kaminski, S Tait - Journal of Volcanology and Geothermal …, 2008 - Elsevier
Explosive volcanic eruptions propel high-velocity turbulent jets into the atmosphere and are
one of the most powerful and dangerous turbulent flows on Earth. Such eruptions are …

Magma yield stress and permeability: Insights from multiphase percolation theory

SDC Walsh, MO Saar - Journal of Volcanology and Geothermal Research, 2008 - Elsevier
Magmas often contain multiple interacting phases of embedded solid and gas inclusions.
Multiphase percolation theory provides a means of modeling assemblies of these different …
