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...

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...

VUELCO deliverable 7.5: Guidelines for the best practice of scientific management of volcanic unrest
09 Sep 2015 | Publications | Contributor(s): dmitri rouwet
Volcanic eruption forecasting and hazard assessment are multi-disciplinary processes with scientific and social implications. Our limited knowledge and the randomness of the processes behind a volcanic eruption yields the need of quantifying uncertainties on volcano dynamics. With deterministic...
