  1. Updated version of an algorithm for tephra isopach, extent and volume calculation in R

    18 Oct 2016 | Contributor(s):: Marcus I Bursik, Qingyuan Yang

    We have updated an algorithm that aids in isopach construction, and volume and extent calculation of tephra fall deposits.  The program is written in R.  Documentation has been improved, and we now include example datasets for the North Mono eruption and Fogo A.  The algorith and...

  2. Los depósitos de caída de tefra: Una breve revisión sobre su cuantificación y análisis para la clasificación de erupciones volcánicas explosivas, con ejemplos Latinoamericanos

    15 Nov 2015 | Contributor(s):: Jorge E. Romero

    La cuantificación de los depósitos volcánicos es una de las herramientas más utilizadas en la actualidad para clasificar la magnitud de la actividad volcánica y determinar los peligros volcánicos asociados. En el caso especial de las erupciones...

  3. Spread sheet to calculate tephra volume for exponential thinning

    03 Dec 2014 | Contributor(s):: Manuel Nathenson, Judy Fierstein

    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...

  4. TError: towards a better quantification of the uncertainty propagated during the characterization of tephra deposits

    28 Nov 2014 | Contributor(s):: Sebastien Biass, Gholamohssein Bagheri, William Aeberhard, Costanza Bonadonna

    NOTE The code is now maintained on GitHub: https://github.com/e5k/TErrorFollow updates on: https://e5k.github.io/  Eruption Source Parameters (ESP; e.g. plume height, erupted volume/mass, mass eruption rate, eruption duration) inferred from tephra deposits are associated with large degrees...
