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 2014 - Maximizing the potential of tephra for multidisciplinary science
09 Jan 2014 | Contributor(s): Steven Kuehn, Solene Pouget, Marcus I Bursik
Tephra deposits are used by diverse communities: volcanologists, petrologists, tephrochronologists, paleoclimatologists, paleoecologists and archaeologists. To perhaps be too reductionist, volcanologists are generally interested in tephra to understand eruption behavior, frequency, and hazards;...

Long Valley volcanic region: geochemical data, cluster analysis and illustrations
24 Apr 2012 | Data Sets/Collections | Contributor(s): Solene Pouget, Marcus I Bursik, Galina Rogova
Separate batches of differentiated magma are often delineated by looking at clusters of points on binary oxide diagrams. However, these are neither directly amenable to statistical analysis, nor do they use all the data available at the time to form the clusters. It is possible to...
