  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. Volcanic welding model: VolcWeld

    09 Jul 2019 | Contributor(s):: Jeremie Vasseur, Fabian Ben Wadsworth

    We provide two products to solve a range of volcanic welding problems. (1) Executable files for Linux or Mac products that solve diffusion of water in rhyolitic volcanic particles during welding with outputs of the average remnant water and the porosity with time. (2) An editable Excel file for...
