  1. Natural Hazards Tephra Fallout Lab

    04 Mar 2011 | | 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...

    17 Apr 2018 | | 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...

    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...

  15. Maar-diatremes - a course module

    out of 5 stars 

    13 Jun 2016 | | 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...
