10-10-10-10-10-10-10-10-10-10-10 From: "Meredith, Elinor (UT-ITC)" <e.s.meredith@xxxxxxxxxx> The Cities and Volcanoes (CAV) Commission is sponsoring four sessions this year. The deadline for abstracts is *Friday 10 January*. We encourage you to submit an abstract to one of our sessions: *Advances in volcanic impact and risk assessments: dynamic and complex methods for dynamic and complex systems* Our understanding of volcanic impacts to surrounding communities, assets, and systems has increased substantially over recent decades. Emerging research is challenging the traditional view of volcanic impact and risk assessment by characterising dynamic, multi-hazard impact and risk across multiple vulnerability dimensions. This session will provide an opportunity to share novel quantitative and qualitative methodologies for the assessment of complex and dynamic volcanic impact and risk. We are particularly interested in approaches that explore cascading and systemic impacts and risk, longitudinal impacts, and co-production of tools and knowledge (including the weaving of indigenous understanding) to enhance volcanic risk management. This session will be comprised of presentations that focus on innovative volcanic impact and risk research, including examples of implementation in practice and policy. This will be followed by lightning talks that will open brief discussions identifying knowledge gaps and collaborative opportunities. We invite abstracts for talks and titles for lightning talks. This session is sponsored by the IAVCEI Commissions on Cities and Volcanoes, Volcanic Hazards and Risk, and Statistics in Volcanology. CONVENERS Alana Weir (University of Geneva, Geneva, Switzerland) Heather Craig (University of Canterbury, Christchurch, New Zealand) Pablo Salgado (National Scientific and Technical Research Council of Argentina, Buenos Aires, Argentina) Eleanor Tennant (Nanyang Technological University (NTU), Singapore, Singapore) Beth Bartel (United States Geological Survey (USGS), Vancouver, United States) *Operational hazard forecasts: source parameters and model evaluation* Volcanic eruptions can last from minutes through decades, and produce hazards that can impact hundreds of square meters through to the entire globe. While an eruption is imminent and/or ongoing, there is a need to produce authoritative, timely, and accurate hazard forecasts for potentially affected areas. Operational forecasts follow an established protocol (generally specific to the responsible entity) for the generation and issuance of the forecast, using an identified numerical model(s). The model requires the input of event-specific parameters, such as vent location, mass eruption rate (effusion rate), eruption duration, and other parameters specific to the hazard. We welcome contributions on how initial model parameters are selected, how parameters are input and updated in near real time, and how operational model performance is evaluated and improved upon. We particularly invite contributions from volcano observatories, Volcanic Ash Advisory Centers, and others with mandates to generate and disseminate operational hazard forecasts. This session is sponsored by the World Organization of Volcano Observatories (WOVO), the World Meteorological Organization Advisory Group on Volcanic Science for Aviation Applications (WMO AG-VSA), and the IAVCEI Commission on Tephra Hazard Modelling. CONVENERS Natalia Deligne (U.S. Geological Survey â?? Hawaiian Volcano Observatory, Hilo, Hawaii, United States) Thomas Aubry (University of Exeter, Penryn, United Kingdom) Samantha Engwell (British Geological Survey â?? Edinburgh, Edinburgh, United Kingdom) Annalisa Cappello (Istituto Nazionale di Geofisica e Vulcanologia â?? Catania, Catania, Italy) *What should we do? Communication of volcanic hazard and risk for decision-making* Volcano science holds crucial information for decision-makers of all levels, from the common citizen to community-scale organizations, civil protection agencies, national leaders, and international bodies such as the United Nations. Our approach to communicating volcano science must keep pace with evolving technologies and our understanding of how this information is used. In this session, we welcome presentations of research on, experience in, and/or vision for how to produce useful decision-making tools: what tools effectively inform long- and short-term decisions; how user engagement and co-creation inform these communication practices; when and how to move beyond hazards and incorporate risk into communication of threats; and how we can utilize or imagine new technologies that facilitate information exchange. Contributors of all career stages are welcome, though students and early career scientists are especially encouraged to participate. What is the future of communication of volcanic hazard and risk? This session is sponsored by the IAVCEI Commission on Cities and Volcanoes. CONVENERS Beth Bartel (USGS Volcano Hazards Program, Vancouver, WA, United States) Omari Graham (UWI Seismic Research Centre, St. Augustine, Trinidad and Tobago) Rebecca Fitzgerald (GNS Science, Lower Hutt, New Zealand) Alana Weir (University of Geneva, Geneva, Switzerland) Daniel Sierra (IGEPN, Quito, Ecuador) *Low-probability high-impact eruptions* Past large-scale eruptions such as the VEI 7 Rinjani and Tambora eruptions in 1257 CE and 1815 CE caused catastrophic global impacts. Although the probability of a future VEI 7 eruption is quite low (1 to 2 per millennia), such events would cause widespread cascading effects and impacts on hemispherical to global scales. Growing population exposures to volcanic hazards and increasing dependence on interconnected infrastructure systems and economic sectors amplify these risks. This potential for severe and far-reaching impacts necessitates diligent mapping and monitoring, preparedness, and international planning and cooperation. This session aims to explore strategies to better understand and prepare for low-probability high-impact eruptions. Topics include analysis of past events and their frequencies (including studies describing the spatial and temporal evolution of discernible eruptive phases); geochemical-geophysical observations; numerical hazard modelling; risk, exposure, and impact assessments; climatic effects; and strategies for effective communication, preparedness, and overall risk assessment. This session is sponsored by the IAVCEI Commission on Cities and Volcanoes.
