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...
Workshop on the Impacts associated with the primary fallout of volcanic ash and subsequent aeolian remobilisation, Consensual Document
19 May 2020 | Publications | Contributor(s):: Lucia Dominguez, Costanza Bonadonna, Donaldo Bran
The inherent complexity associated with volcanic eruptions and their relationship with societies requires innovative strategies about how we assess and manage risk. The 2011 Cordón Caulle eruption (2011-CC) demonstrated the additional complexity associated with secondary hazards and...
Workshop on Wind-remobilisation processes of volcanic ash, Consensual Document
20 Feb 2020 | Publications | Contributor(s):: Costanza Bonadonna, Paul A Jarvis, Lucia Dominguez, Corine Frischknecht, Pablo Forte, Donaldo Bran, Rigoberto Aguilar, Frances Beckett, Manuela Elissondo, Jack Gillies, ulrich kueppers, Jonathan Merrison, Nick Varley, Kristi L Wallace
Explosive volcanic eruptions can eject large quantities of tephra into the atmosphere that can be dispersed and deposited over wide areas. Whilst the hazardous consequences of primary tephra fallout are well known, subsequent remobilisation of ash by aeolian processes can continue to present an...
