Maar-diatremes - a course module
13 Jun 2016 | Contributor(s): Greg A Valentine, Alison Graettinger
Maar-diatremes are one of the most common volcanic landforms on Earth, and represent an end-member type of volcano whose eruptions are dominated by explosive, subsurface magma-water interaction. Thus they should form an important component of volcanology courses. The recent decade has...

Tephra isopach, extent and volume calculation in R
04 Mar 2016 | Contributor(s): Qingyuan Yang, Marcus I Bursik
The method presented here is used to interpolate the thickness distribution of tephra fall deposits from point measurements. It first reconstructs the general thickness decay pattern, or "trend," and then models the residuals that cannot be explained by the trend with...

ASHEE
14 Aug 2015 | Contributor(s): Matteo Cerminara, Tomaso Esposti Ongaro
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...

Tephra 2014 - Maximizing the potential of tephra for multidisciplinary science
09 Jan 2014 | Contributor(s): Steven Kuehn, Solene Pouget, Marcus I Bursik
Tephra deposits are used by diverse communities: volcanologists, petrologists, tephrochronologists, paleoclimatologists, paleoecologists and archaeologists. To perhaps be too reductionist, volcanologists are generally interested in tephra to understand eruption behavior, frequency, and hazards;...

An assessment of hydrothermal alteration in the Santiaguito lava dome complex, Guatemala: implications for dome collapse hazards
28 Feb 2013 | Publications | Contributor(s): Jessica L. Ball, Eliza S Calder, Marc Bernstein
A combination of field mapping, geochemistry, and remote sensing methods has been employed to determine the extent of hydrothermal alteration and assess the potential for failure at the Santiaguito lava dome complex, Guatemala. The 90-year-old complex of four lava domes has only experienced...
