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...

Abstracts from the UK community meeting on the Eyjafjallajökull eruption, April 2010.

28 Feb 2011

This is the meeting abstract volume from a rapidly assembled UK community-wide meeting to discuss the Eyjafjallajökull eruption and its consequences. The meeting was supported by the UK National Centre for Earth Observation (NCEO; Natural Hazards theme, http://comet.nerc.ac.uk) and the...

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

28 Feb 2013

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...

Detecting volcanic ash from space

How satellites detect, map and measure volcanic ash in volcanic clouds. HYSPLIT and volcanic cloud satellite observations. Volcanic cloud stages. Infrared satellite detectors, split window. Evolution of volcanic clouds from space platforms.Rose, W I, G J S Bluth, D J Schneider, G G J Ernst, C M...

Direct sampling of volcanic clouds

08 Feb 2011

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...

eject model

28 Jan 2021

Eject is a user-friendly model that calculates the trajectories of blocks that are ballistically ejected from volcanic craters. It has also been used to calculate ballistic trajectories of other objects in other other settings, including missiles and bullets.Details are at:The attached zip...

Eruption data for ash-cloud model validation

28 Jan 2021

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...

Mapping a 49 year old eruption of a basaltic cone: Pacaya Guatemala

28 Jan 2021

This presentation summarizes the 50 year eruption and the 3 dimensional map produced. The map, prepared as part of an MS thesis by Ruben Otoniel Matias Gomez, is under review as a Map and Chart Series publication by the GSA. The lecture summarizes the situation at Pacaya, and uses Matias' map as...
