1st IAVCEI/GVM Workshop: "From Volcanic Hazard to Risk Assessment", Geneva, 27-29 June 2018
18 Dec 2018 | Workshops | Contributor(s): E Bruce Pitman, Abani Patra
The complexity of volcanic risk analysis typically resides in the interaction of multiple hazard, vulnerability and exposure aspects dynamically acting over various spatial and temporal scales. Risk analyses provide an evidence-based approach to development and implementation of proactive...

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
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...
bent: A model of plumes in crossflow
11 Nov 2010 | Presentations | Contributor(s): Marcus I Bursik
Bent is an integral trajectory model for calculation of plume parameters in the presence of a crossflow (wind). It has been validated against data for eruptions from Kliuchevskoi and Avachinskiy volcanoes, Russia.

Confort 15 (Conflow improvement)
22 Apr 2016 | Offline Tools | Contributor(s): Marcus I Bursik
We present an updated version of the Conflow model, an open-source numerical model for flow in eruptive conduits during steady-state pyroclastic eruptions (Mastin and Ghiorso, 2000). In the Confort 15 program, several updates were considered:The rheological parameters of the model are...

Estimating Volcanic Risk in the Lesser Antilles
26 Sep 2013 | Publications | Contributor(s): E Bruce Pitman, Abani Patra
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): E Bruce Pitman, Abani Patra
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
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
28 Feb 2021 | Educational Materials
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...
