Workshop on the Impacts associated with the primary fallout of volcanic ash and subsequent aeolian remobilisation

19 May 2020 | Workshops | 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...

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...

Probabilistic studies with Eject! for Matlab

25 Jun 2019 | Offline Tools | Contributor(s): Karen Strehlow, Laura Sandri, Jo Gottsmann, Geoff Kilgour, Alison Rust, Roberto Tonini

Using a translation of the code of Eject! (Mastin 2001; 2011) in Matlab (Strehlow et al., 2019), we provide a workflow for probabilistic analyses of ballistic ejections during volcanic eruptions that can be used for hazard assessments. An example for the use of this workflow...

Eject! for Matlab
