Workshop on the Impacts associated with the primary fallout of volcanic ash and subsequent aeolian remobilisation, Consensual Document
10 May 2021 | Publications
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
10 May 2021 | Publications
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...
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): Marcus I Bursik
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): Marcus I Bursik
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...

18 Feb 2014 | Workshops
An international expert community of volcano observatories, academic scientists, volcanic ash advisory centres and representatives of aviation regulators, engine manufacturers and airlines met in Geneva on 18-20 November 2013 to discuss progress on ash dispersal forecasting and produce a roadmap...
Eruption data for ash-cloud model validation
04 Apr 2013 | Data Sets/Collections
This is a collection of data, references, and links to data on well-documented eruptions whose observations can be used to validate ash-cloud transport models. Data include, among other things, plume height, duration, erupted volume, satellite observations, numerical wind fields, and grain-size...
Volcanic clouds observed by the A-Train satellite constellation
12 Mar 2012 | Data Sets/Collections
A collection of images showing volcanic eruption clouds detected by NASA's A-Train satellite constellation, which includes the Aqua, CALIPSO, CloudSat and Aura satellites. These examples demonstrate the unique ability of the A-Train to provide coincident, multi-spectral, active and passive remote...

05 Aug 2011 | Workshops
A workshop at the 2011 IUGG General Assembly in Melbourne, Australia, lead by Andrew Tupper (Australian Bureau of Meteorology), Fred Prata (Norwegian Institute for Air Research), and Arnau Folch (Barcelona Supercomputing Center).The Eyjafjallajokull eruption, resulting in ground and air...
Large Scale Experiments on Volcanic Processes (EOS)
19 Jul 2011 | Publications
Some of the least understood and most hazardous geologic processes involve complex multiphase flows, particularly those related to explosive volcanic eruptions. These phenomena inherently involve a wide range of characteristic length and time scales, as well as processes that are coupled across...

Direct sampling of volcanic clouds
08 Feb 2011 | Presentations
Volcanic clouds have only sporadically been directly sampled. Sampling is advantageous to validate remote sensing. Direct sampling was more common in the 1978-1984 period before the hazards to jet aircraft were understood and when piston aircraft sampling was more prevalent. This sampling...
