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

    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...

    Fluid-solid coupling drives the dynamic systems of volcanoes, earthquakes, and tsunamis. Magma-filled dikes propagate within active volcanoes. Megathrust earthquakes shift the seafloor and excite...
