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...

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...

PYFLOW_2.0. A new tool for estimating the impact parameters and the deposition rate and time of dilute PDCs based on field data

22 Nov 2017 | Offline Tools | Contributor(s): Fabio Dioguardi, Daniela Mele, Pierfrancesco Dellino

PYFLOW_2.0 is a hazard tool for the calculation of the impact parameters of dilute pyroclastic density currents (DPDCs). DPDCs represent the dilute turbulent type of gravity flows that occur during explosive volcanic eruptions; their hazard is the result of their mobility and the capability...

Confort 15 (Conflow improvement)

22 Apr 2016 | Offline Tools | Contributor(s): Silvia Campagnola, Claudia Romano, Larry G Mastin, Alessandro Vona

We present an updated version of the Conflow model, an open-source numerical model for flow in eruptive conduits during steady-state pyroclastic eruptions (Mastin and Ghiorso, 2000). In the Confort 15 program, several updates were considered:The rheological parameters of the model are...
