  1. 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...

  2. 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...

  3. 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...

  4. Probabilistic hazard maps of pyroclastic density currents in the Long Valley Volcanic Region

    08 Aug 2019 | Data Sets/Collections | Contributor(s):: Regis Rutarindwa, Elaine Spiller, Andrea Bevilacqua, Marcus I Bursik, Abani Patra

    This is a repository of the maps and graphs of PDC inundation probability distributions and related uncertainty indices for the Long Valley volcanic region, according to the physical and statistical model in: Regis Rutarindwa, Elaine T. Spiller, Andrea Bevilacqua, Marcus I. Bursik, and Abani...

  9. Volcanic welding model: VolcWeld

    09 Jul 2019 | Offline Tools | Contributor(s):: Jeremie Vasseur, Fabian Ben Wadsworth

    We provide two products to solve a range of volcanic welding problems. (1) Executable files for Linux or Mac products that solve diffusion of water in rhyolitic volcanic particles during welding with outputs of the average remnant water and the porosity with time. (2) An editable Excel file for...
