Workshop on Wind-remobilisation processes of volcanic ash, Consensual Document
29 Mar 2020
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
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:...
Pyroclastic density currents and local topography as seen with the conveyer model
15 Apr 2014
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...

This workshop was undertaken before the IAVCEI conference in July 2013, complementing the session on "Stress, strain and mass changes at active volcanoes. It brings together seismic and geodetic methods and computational approaches for modelling volcanic processes.Material presented includes:1....
Eruption data for ash-cloud model validation
04 Apr 2013
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
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...
