  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...

  5. 1st IAVCEI/GVM Workshop: "From Volcanic Hazard to Risk Assessment", Geneva, 27-29 June 2018

    18 Dec 2018 | Workshops | Contributor(s): Costanza Bonadonna, Sebastien Biass, Eliza S Calder, Corine Frischknecht, Chris Eric Gregg, Susanna Jenkins, Sue C Loughlin, Scira Menoni, Shinji Takarada, Tom Wilson

    The complexity of volcanic risk analysis typically resides in the interaction of multiple hazard, vulnerability and exposure aspects dynamically acting over various spatial and temporal scales. Risk analyses provide an evidence-based approach to development and implementation of proactive...

  6. A new method to identify the vent location of tephra fall deposits based on thickness or maximum clast size measurements (SVL)

    17 Apr 2018 | Offline Tools | Contributor(s): Qingyuan Yang, Marcus I Bursik, E Bruce Pitman

    This tool presents a new method to identify the vent location of tephra fall deposits based on thickness or maximum clast size measurements. It is temporarily named "svl", which is short for Source Vent Locator. The method estimates the vent location by coupling semi-empirical models...

  14. Maar-diatremes - a course module

    13 Jun 2016 | Educational Materials | Contributor(s): Greg A Valentine, Alison Graettinger

    Maar-diatremes are one of the most common volcanic landforms on Earth, and represent an end-member type of volcano whose eruptions are dominated by explosive, subsurface magma-water interaction.  Thus they should form an important component of volcanology courses.  The recent decade has...
