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...
TError: towards a better quantification of the uncertainty propagated during the characterization of tephra deposits
28 Nov 2014 | Contributor(s):: Sebastien Biass, Gholamohssein Bagheri, William Aeberhard, Costanza Bonadonna
NOTE The code is now maintained on GitHub: https://github.com/e5k/TErrorFollow updates on: https://e5k.github.io/ Eruption Source Parameters (ESP; e.g. plume height, erupted volume/mass, mass eruption rate, eruption duration) inferred from tephra deposits are associated with large degrees...
Estimation and propagation of volcanic source parameter uncertainty in an ash transport and dispersal model: application to the Eyjafjallajokull plume of 14--16 April 2010
19 Sep 2012 | Contributor(s):: Marcus I Bursik
Data on source conditions for the 14 April 2010 paroxysmal phase ofthe \eyja~ eruption, Iceland, have been used as inputs to atrajectory-based eruption column model, . This model has inturn been adapted to generate output suitable as input to the volcanicash transport and dispersal model, , which...
