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...

Estimating Volcanic Risk in the Lesser Antilles
26 Sep 2013 | Publications | Contributor(s): Michal Camejo, Richard E.A. Robertson
The potential catastrophic effects of future volcanic eruptions in the Lesser Antilles can be decreased by the utilisation of effective risk quantification measures and their subsequent incorporation into disaster risk reduction strategies. A volcanic risk study conducted by the Norwegian...

La erupción del volcán Calbuco en 2015: Volcanología, sociedad y ecosistemas
25 Apr 2017 | Publications | Contributor(s): Jorge E. Romero
La erupción del 22-23 de abril de 2015 del Volcán Calbuco tuvo impactos en las actividades sociales y ecosistemas en el sur de Chile y en Argentina, debido a la espesa caída de piroclastos, corrientes calientes de gases y rocas, además de flujos de lodo...
Large Scale Experiments on Volcanic Processes (EOS)
19 Jul 2011 | Publications | Contributor(s): Greg A Valentine
Some of the least understood and most hazardous geologic processes involve complex multiphase flows, particularly those related to explosive volcanic eruptions. These phenomena inherently involve a wide range of characteristic length and time scales, as well as processes that are coupled across...
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...
