Volcanic unrest: Interfacing science and decision-making

Sun. 18 November
Leader: Jo Gottsman
Cost: No cost to VUELCO participants. US$10 cost for lunch/coffee for non-participants (payable on the day).

Volcanic unrest is a complex multi-hazard phenomenon of volcanism. Our knowledge of the causative links between subsurface processes, resulting unrest signals and imminent eruption, today, is incomplete to deal effectively with crises of volcanic unrest.

When a volcano develops from dormancy through a phase of unrest important scientific, political and social questions need to be addressed. Scientific questions relate to the processes behind unrest and their associated surface signals (if any), their future evolution and their significance as precursor for eruptive phenomena. Political and social questions are related to: (i) how epistemic and aleatory uncertainties surrounding data and processes are employed in the light of probabilistic assessment of outcomes of unrest periods, (ii) how these uncertainties are communicated and (iii) how evolving crises are best managed depending on the forecasted scenario.

The purpose of this workshop is to sample and discuss the state-of-the-art and future challenges of volcanic unrest research by an amalgamation of contributions from the natural and social sciences and from non-scientific stakeholders.

We aim at bringing together natural and social scientists, decision makers and policy makers to discuss issues relevant to the scientific, risk and managerial aspects of volcanic unrest. We particularly welcome contribution from cross-boundary research across the disciplines relevant for the study of volcanic unrest and its management.

This workshop is sponsored by the European Commission under the 7th framework programme for research and technological development via the "VUELCO" project.

Volcano Monitoring Techniques

Sat. 17 November 2012
Leaders: Jeff Johnson & Nick Varley
Cost: US$50 for salaried participants & US$25 for students including lunch and materials.
50 people

Innovation in volcano monitoring techniques is rapid. In the search for eruption precursors, the more traditional areas of seismicity, geodesy and geochemistry are now routinely complemented by studies of acoustic or thermal emission. We are also beginning to better understand the significance of many other detectable geophysical signals, including deformation, gravity, and electromagnetic signals. In recent years there has been a move to more remote sensing techniques, which allow a wider coverage and a decreased risk for the volcanologist. The usage and applications of satellite data is also increasing dramatically. Much more attention is being placed on the integration of diverse monitoring techniques both for improved monitoring capabilities and understanding of eruption dynamics.

This workshop will summarize the state-of-the-art of the most important areas of volcano monitoring. The day will be divided into the following themes with specialists presenting the theory and implementation of the various techniques. We hope to attract graduate students and observatory staff who require some refreshment regarding what data is available, how it can be obtained and then integrated into models of volcano behaviour.

Workshop of the Volcanic Ashfall Impacts Working Group and International volcanic Health hazards Network

Sun. 18 November
Leaders: Thomas Wilson, Kristi Wallace, Graham Leonard, Claire Horwell & Peter Baxter
Cost: US$15, including lunch.
40 people

The Ash Impacts Working Group is formally hosted by the Cities and Volcanoes (CAV) Commission of IAVCEI. It is an international consortium of multi-disciplinary geoscientists including membership from several other working groups and commissions which helps to create transparency between groups and show collaboration on common missions. The core objective of the working group is to improve ash fall impact data, data collection, warnings and other mitigation strategies.

The International Volcanic Health Hazard Network ( was established a decade ago and is the umbrella organisation for all volcanic health-related research and dissemination. As well as providing public information during volcanic crises, IVHHN facilitates urgent analyses during eruptions, collaborating with governments, health agencies and NGOs, and provides guidelines and pamphlets on health strategies.

This workshop will cover 6 core themes:
Theme 1: More Effective Ash Fall Warning Messages
Theme 2: Protocols for Ash Fall Data Collection and Analysis
Theme 3: Checklist of Topics & Indicators to Collect Impact Data Following Eruptions
Theme 4: Ash Impacts Loss-damage Functions for Risk Calculations
Theme 5: Improve International Ash Fall Impact Data - Image Repository - Communications
Theme 6: Assessing ash impacts in a crisis – national and international communication and dissemination

VHub: A Platform to Share, Compare, Validate, and Verify Models and Information

17:00 – 19:00 Sun. 18 November
Leader: Sylvain Charbonnier
No cost.

VHub (online at is a virtual organization and community cyberinfrastructure designed for collaboration in volcanology research, education, and outreach. One of the core objectives of this project is to accelerate the transfer of research tools to organizations and stakeholders charged with volcano hazard and risk mitigation (such as volcano observatories). VHub offers a clearinghouse for computational models of volcanic processes and data analysis, documentation of those models, and capabilities for online collaborative groups focused on issues such as code development, configuration management, benchmarking, and validation. VHub supports computer simulations and numerical modelling at two levels: (1) some models can be executed online via VHub, without needing to download code and compile on the user’s local machine; (2) other models are not available for online execution but for offline use in the user’s computer. VHub also has wikis, blogs and group functions around specific topics to encourage collaboration, communication and discussion.

This two-hour workshop will focus on the uses and applications of online simulation tools and other Vhub features for assessing volcanic hazards. Attention is drawn to the minimum computational resources needed by the user to carry out such analyses, and to the tools and media provided to facilitate the effective use of VHub’s infrastructure for hazard and risk assessment.

The workshop will consist of 2 hours of presentations plus a Q&A session. There will be four 20-minute presentations that focus on of useful aspects of VHub:

1)   Introduction to VHub - Sylvain Charbonnier 20 min
2)   Use of TITAN on VHub - Sylvain Charbonnier 20 min
3)   Use of Tephra2 on VHub - Leah Courtland 20 min
4)   Use of GeoProMT on VHub - Chris Renschler 20 min
5)   Discussion and questions (VHub team) 40 min including live demonstrations
