1. Tephra inversion with Tephra2 and the Metropolis-Hastings algorithm

   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...

   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...

3. 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

   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...
