COUPLING OF VISCOUS AND DIFFUSIVE CONTROLS ON BUBBLE GROWTH DURING EXPLOSIVE VOLCANIC ERUPTIONS

Blower J.D.; Mader H.M.; Wilson S.D.R. (2001)

The coupling of viscosity and diffusivity during explosive volcanic degassing is investigated using a numerical model of bubble growth in rhyolitic melts. The model allows melt viscosity and water diffusivity to vary ...
EXPERIMENTAL OBSERVATIONS OF THE EFFECT OF CRYSTALS AND PRE-EXISTING BUBBLES ON THE DYNAMICS AND FRAGMENTATION OF VESICULATING FLOWS

Mourtada-Bonnefoi C.C.; Mader H.M. (2004)

The effect of crystals and pre-existing gas phases on the dynamic degassing and fragmentation of magmas in a volcanic conduit have been simulated by analogue experiments. A series of decompression experiments of viscous ...
THE EVOLUTION OF BUBBLE SIZE DISTRIBUTIONS IN VOLCANIC ERUPTIONS

Blower J.D.; Mader H.M.; Phillips J.C.; Keating J.P. (2003)

We review observations of bubble size distributions (BSDs) generated during explosive volcanic eruptions and laboratory explosions, as inferred from vesicle size distributions found in the end products. Unimodal, polymodal, ...
THE ROLE OF LABORATORY EXPERIMENTS IN VOLCANOLOGY

Mader H.M.; Manga M.; Koyaguchi T. (2004)

Experiment is central to scienti¢c methodology. Within science in general, experiments are used for four primary purposes, i.e. as a tool to explore novel phenomena and to provide systematic observations of processes, to ...
