  1. Natural Hazards Tephra Fallout Lab

    04 Mar 2011 | Educational Materials | Contributor(s): Leah Michelle Courtland

    This lab walks students through using the tephra2 education graphical user interface (gui) to investigate tephra fallout at Colima volcano. By the end of this lab, students should be able to:•understand that every volcanic event is different and so produces a unique deposit•convert from units of...

  2. 1st IAVCEI/GVM Workshop: "From Volcanic Hazard to Risk Assessment", Geneva, 27-29 June 2018

    18 Dec 2018 | Workshops | Contributor(s): Costanza Bonadonna, Sebastien Biass, Eliza S Calder, Corine Frischknecht, Chris Eric Gregg, Susanna Jenkins, Sue C Loughlin, Scira Menoni, Shinji Takarada, Tom Wilson

    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...

  4. 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...

  5. 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...

  10. 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...

    27 Apr 2011 | Presentations | Contributor(s): William I Rose

    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...
