  1. A new method to identify the vent location of tephra fall deposits based on thickness or maximum clast size measurements (SVL)

    17 Apr 2018

    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...

    15 Sep 2016

    Download the code on GitHub: https://github.com/e5k/TephraProbFollow updates on: https://e5k.github.io/TephraProb is a toolbox of Matlab functions designed to produce scenario–based probabilistic hazard assessments for ground tephra accumulation. The toolbox includes a series of...

  6. Maar-diatremes - a course module

    25 Feb 2020

    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...

  7. Tephra isopach, extent and volume calculation in R

    25 Feb 2020

    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...

    25 Feb 2020

    Download the code on GitHub: https://github.com/e5k/CareySparks86_MatlabFollow updates on: https://e5k.github.io/   This file is a Matlab implementation of the Carey and Sparks (1986) model to estimate i) the plume height above sampling altitude and ii) the wind speed at the...

  9. Tephra 2014-2020 Document Repository

    01 Jul 2015

    Beginning with the consensus document (with three appendices) resulting from the Tephra 2014 Workshop, this is the document repository for the Tephra 2014, 2017 and 2020 Workshops on standardization.The immediate goal of the tephra standardization effort is to translate checklists...

  10. Spread sheet to calculate tephra volume for exponential thinning

    10 Apr 2015

    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...

  12. TOTGS: Total grainsize distribution of tephra fallout

    20 Jan 2014

    NOTE The code is now maintained on GitHub: https://github.com/e5k/TOTGS Follow updates on: https://e5k.github.io/  Quantifying the total grainsize distribution (TGSD) is a necessary step to achieve a thorough characterization of a given tephra deposit. Several methods exist to...

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

    09 Jan 2014

    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;...

  14. An assessment of hydrothermal alteration in the Santiaguito lava dome complex, Guatemala: implications for dome collapse hazards

    28 Feb 2013

    A combination of field mapping, geochemistry, and remote sensing methods has been employed to determine the extent of hydrothermal alteration and assess the potential for failure at the Santiaguito lava dome complex, Guatemala. The 90-year-old complex of four lava domes has only experienced...
