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

    21 Jun 2020 | Contributor(s): Qingyuan Yang, E Bruce Pitman, Marcus I Bursik, Susanna Jenkins

    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...

  2. Tephra isopach, extent and volume calculation in R

    04 Mar 2016 | Contributor(s): Qingyuan Yang, Marcus I Bursik

    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...

  3. Tephra2

    20 Apr 2010 | *Tools | Contributor(s): Costanza Bonadonna, Laura Connor, Chuck B Connor, Leah Michelle Courtland

    Tephra2 uses the advection diffusion equation to forecast tephra dispersion in a given location based on a user-defined set of eruptive conditions.

    Tephra2 uses the advection diffusion equation to forecast tephra dispersion in a given location based on a user-defined set of eruptive conditions.Tephra2 codes are now maintained on GitHub: https://github.com/geoscience-community-codes/tephra2 Available are:1-processor...

  5. Tephra2: Student Version

    21 Feb 2011 | *Tools | Contributor(s): Leah Michelle Courtland, Chuck B Connor, Laura Connor, Costanza Bonadonna

    The Tephra2 ash dispersion model run via a GUI designed for student use.

  6. TephraProb: a Matlab package for probabilistic hazard assessments of tephra fallout

    15 Sep 2016 | Offline Tools | Contributor(s): Sebastien Biass, Costanza Bonadonna, Laura J Connor, Chuck B Connor

    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...

  7. TOTGS: Total grainsize distribution of tephra fallout

    20 Jan 2014 | Offline Tools | Contributor(s): Seb Biass, Costanza Bonadonna

    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...
