A new method to identify the vent location of tephra fall deposits based on thickness or maximum clast size measurements (SVL)
17 Apr 2018 | Offline Tools | Contributor(s): Qingyuan Yang, Marcus I Bursik, E Bruce Pitman
This tool presents a new method to identify the vent location of tephra fall deposits based on thickness or maximum clast size measurements. It is temporarily named "svl", which is short for Source Vent Locator. The method estimates the vent location by coupling semi-empirical models...

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...

ASHEE
14 Aug 2015 | Offline Tools | 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...

Maar-diatremes - a course module
13 Jun 2016 | Educational Materials | 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...
