  1. Natural Hazards Tephra Fallout Lab

    29 Mar 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...

  8. Maar-diatremes - a course module

    29 Mar 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...

  13. Shawn's Contribution

    29 Mar 2020 | Miscellaneous | Contributor(s): Shawn Rice, Nicholas J. Kisseberth

    The contribution process is intended to be much like composing an e-mail: You'll start with writing the introduction and main content of your contribution and later attach files to it (video, PDFs, etc).The abstract is typically a one or two paragraph description of your contribution.

  14. Spread sheet to calculate tephra volume for exponential thinning

    29 Mar 2020 | Offline Tools

    An Excel spread sheet and instructions are provided to calculate tephra volume for exponential thinning on a log(thickness) versus square root of area plot. The spread sheet calculates volumes for a single straight line and for two straight lines. The equations for the calculations are from...

  15. Tephra 2014 - Maximizing the potential of tephra for multidisciplinary science

    29 Mar 2020 | Workshops

    Tephra deposits are used by diverse communities: volcanologists, petrologists, tephrochronologists, paleoclimatologists, paleoecologists and archaeologists. To perhaps be too reductionist, volcanologists are generally interested in tephra to understand eruption behavior, frequency, and hazards;...
