    08 Dec 2014

    Guidebook for the field trip to Mount Saint Helens conducted 4-August-2014 as part of the Tephra 2014 workshop.

  2. 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 2019 Workshops on standardization.The immediate goal of the tephra standardization effort is to translate checklists...

  3. Tephra 2017 Workshop : Best practices in tephra collection, analysis, and reporting leading toward better tephra databases

    15 Jun 2017

    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...

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

    16 Jan 2022

    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...

  6. Tephra isopach, extent and volume calculation in R

    16 Jan 2022

    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...

  13. Volcanic clouds observed by the A-Train satellite constellation

    16 Jan 2022 | Data Sets/Collections

    A collection of images showing volcanic eruption clouds detected by NASA's A-Train satellite constellation, which includes the Aqua, CALIPSO, CloudSat and Aura satellites. These examples demonstrate the unique ability of the A-Train to provide coincident, multi-spectral, active and passive remote...
