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...

MeMoVolc workshop on the "Dynamics of volcanic explosive eruptions", Consensual Document

15 Jul 2014 | Publications | Contributor(s): Costanza Bonadonna, Raffaello Cioni, Antonio Costa, Tim Druitt, Jeremy Phillips, Laura Pioli

This workshop served to assess the main advantages and shortcomings of existing eruption classification schemes and to identify open questions and research priorities that could help improve our understanding of volcanic explosive eruptions. We identified the main parameters and processes...

Determination of the largest clasts of tephra deposits for the characterization of explosive volcanic eruptions: report of the IAVCEI Commission on Tephra Hazard Modelling

27 Jul 2011 | Publications | Contributor(s): Costanza Bonadonna, simona scollo, Raffaello Cioni, Laura Pioli, Marco Pistolesi

This report summarizes the results of the field workshop of the IAVCEI Commission on Tephra Hazard Modelling that was carried out in Salcedo, Ecuador (January 16-18, 2006) with the main objective of assessing the best way to characterize the largest clasts of tephra deposits. Defining the largest...

Ash Dispersal Forecast and Civil Aviation Workshop - Model Benchmark Document

15 Feb 2011 | Publications | Contributor(s): Costanza Bonadonna, Arnau Folch

One of the main objectives of the IAVCEI-WMO Ash dispersal forecast and civil aviation workshop was to investigate the variability of existing Volcanic Ash Transport and Dispersal Models (VATDM) in order to identify new improved strategies of dispersal forecasting, e.g. probability/ensemble...

Ash Dispersal Forecast and Civil Aviation Workshop - Consensual Document

15 Feb 2011 | Publications | Contributor(s): Costanza Bonadonna, Arnau Folch

As a result of the serious consequences of the 2010 Eyjafjallajökull eruption on civil aviation, more than 50 volcanologists, meteorologists, atmospheric dispersion modellers, and space and ground-based monitoring specialists from 12 different countries (including representatives from 6...
