  1. Natural Hazards Tephra Fallout Lab

    25 Nov 2020 | Educational Materials

    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): 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...

  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

    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...

  12. 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...

  13. 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...

  14. Maar-diatremes - a course module

    25 Nov 2020 | 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...
