  1. Workshop on the Impacts associated with the primary fallout of volcanic ash and subsequent aeolian remobilisation, Consensual Document

    28 Oct 2020 | 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...

  2. Workshop on Wind-remobilisation processes of volcanic ash, Consensual Document

    28 Oct 2020 | 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...

  3. ECMapProb

    28 Oct 2020 | Tools

    Probability map of PDC by using a modifed approach of the energy cone model and topographic information derived from the SRTM 30 m elevation model.

  4. 1st IAVCEI/GVM Workshop: "From Volcanic Hazard to Risk Assessment", Geneva, 27-29 June 2018

    18 Dec 2018 | Workshops

    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...

    This is a repository for the data and script used in, "Effect of particle entrainment on the runout of pyroclastic density currents."Here you will find:1. A compilation of splash function experimental data from this study and data that was extracted from seven other studies:...

  8. Pyroclastic density currents and local topography as seen with the conveyer model

    15 Apr 2014 | Publications

    Pyroclastic density currents (PDCs) are multiphase flows generated during explosive volcanic eruptions, and they move down the volcano, and over the surrounding topography. The flow-topography interaction can play a fundamental role in the sedimentary processes, and in the resulting deposit...

  9. 2nd IUGG-WMO Workshop on Ash Dispersal Forecast and Civil Aviation, Consensual Document

    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...

  10. 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...

  11. An assessment of hydrothermal alteration in the Santiaguito lava dome complex, Guatemala: implications for dome collapse hazards

    28 Feb 2013 | Publications

    A combination of field mapping, geochemistry, and remote sensing methods has been employed to determine the extent of hydrothermal alteration and assess the potential for failure at the Santiaguito lava dome complex, Guatemala. The 90-year-old complex of four lava domes has only experienced...
