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