Probability map of PDC by using a modifed approach of the energy cone model and topographic information derived from the SRTM 30 m elevation model.
1st IAVCEI/GVM Workshop: "From Volcanic Hazard to Risk Assessment", Geneva, 27-29 June 2018
18 Dec 2018
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...

Pyroclastic density currents and local topography as seen with the conveyer model
15 Apr 2014
Pyroclastic density currents (PDCs) are multiphase flows generated during explosive volcanic eruptions, and they move down the volcano, and over the surrounding topography. The flow-topography interaction can play a fundamental role in the sedimentary processes, and in the resulting deposit...
Underwater volcano disaster - an Oxford Sparks Animation
19 Mar 2014
A short (2 minute) animation of a subduction zone and volcano, introducing the processes involved in subduction, melting and volcanism.This animation can be used as a stand alone item, or in a classroom. We have developed some class activities around an exercise in volcano monitoring at an...
New Methods and Computer Codes for Volcanic Modelling
18 Jul 2013
This workshop was undertaken before the IAVCEI conference in July 2013, complementing the session on "Stress, strain and mass changes at active volcanoes. It brings together seismic and geodetic methods and computational approaches for modelling volcanic processes.Material presented includes:1....

Mapping a 49 year old eruption of a basaltic cone: Pacaya Guatemala
27 Apr 2011 | Presentations
This presentation summarizes the 50 year eruption and the 3 dimensional map produced. The map, prepared as part of an MS thesis by Ruben Otoniel Matias Gomez, is under review as a Map and Chart Series publication by the GSA. The lecture summarizes the situation at Pacaya, and uses Matias' map as...
