  4. Pyroclastic density currents and local topography as seen with the conveyer model

    24 Jan 2021 | Publications

    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...

  5. Shawn's Contribution

    24 Jan 2021 | 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.

  6. Spread sheet to calculate tephra volume for exponential thinning

    24 Jan 2021 | 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...

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

    24 Jan 2021 | 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;...

  9. Tephra 2014 Field Trip Guide

    Best practices in tephra collection, analysis, and reporting: Leading toward better tephra databasesThis is a page for the Tephra 2017 workshop, held in Portland, OR, 19 August 2017.  The workshop was a follow-on to the Tephra 2014 workshop, held 3-7 August 2014, also in...

  12. Tephra Impact Lab - Taupo Volcano

    06 Dec 2011 | Educational Materials

    This lab requires students to produce a pre-eruption tephra risk assessment for Taupo volcano, using Tephra2. It requires students to consider the eruptive history of Taupo volcano and a volcanic unrest scenario is provided, so that students must decide what magnitude and style of eruption is...

  14. Tephra inversion with Tephra2 and the Metropolis-Hastings algorithm

    24 Jan 2021 | Offline Tools

    We couple the Metropolis-Hastings algorithm (Hastings, 1970) with the volcanic ash transport model Tephra2 (Bonadonna et al, 2005; 2010), and present the coupled algorithm as a new method to estimate the Eruption Source Parameters (ESPs) of volcanic eruptions based on mass per unit area...

  15. Tephra isopach, extent and volume calculation in R

    24 Jan 2021 | Offline Tools

    The method presented here is used to interpolate the thickness distribution of tephra fall deposits from point measurements. It first reconstructs the general thickness decay pattern, or "trend," and then models the residuals that cannot be explained by the trend with...
