7-7-7-7-7-7-7-7-7-7-7-7-7-7 From: Giuseppe Salerno <giuseppe.salerno@xxxxxxx> Dear all, Your abstract submissions are very welcome for the S1.15 Volcanic Degassing: Insights into Volcanic Processes, Impacts and Hazard" at the next COV-11 that will be held in Crete from 23 to 27 May 2020, https://pcoconvin.eventsair.com/volcanoes11/ Deadline: 25 January 2020 Session's description: Volcanoes release gas and aerosol particles into the atmosphere during eruptive episodes and by quiescent emissions. Volcanic degassing exerts a dominant role in forcing the timing and nature of unrests and volcanic eruptions. Understanding the behaviour/exsolution of gases dissolved in magma, and measuring their emissions is crucial to characterise eruptive mechanism and evaluate impacts on health, atmospheric composition and environment. Emissions range from silent exhalation through soils to astonishing eruptive clouds that release gases and particles into the atmosphere exerting a strong impact on the Earthâ??s radiation budget and climate over a range of temporal and spatial scales. Volcanic sulphate aerosols may lead to decrease in Earthâ??s surface temperatures for years, and emitted halogens can perturb atmospheric chemistry. Through direct exposure and indirect effects, volcanic emissions may influence local-to-regional air quality, seriously affect the biosphere and environment, and the release of gas from soil may pose long-term health hazards. Gases are measured and monitored via a range of in-situ and remote sensing techniques, to gain insights into both the subterranean-surface processes and quantify the extent of volcanoâ??s impacts. Modelling of the subsurface and atmospheric processes, as well as laboratory experiments, are fundamental to the interpretation of the field-based and satellite observations. This session focuses on the state of the art and multi-disciplinary science concerning all aspects of volcanic degassing and impacts of relevance to the volcanology, environment, atmospheric/climate science and hazard assessment. We invite contributions discussing how we go from observations to the synoptic understanding of volcanic processes and their impacts. Core connection between the proposed session and societal risk mitigation: health, atmospheric composition and environment. We look forward to meeting you in Crete! 7-7-7-7-7-7-7-7-7-7-7-7-7-7 ============================================================== Volcano Listserv is a collaborative venture among Arizona State University (ASU), Portland State University (PSU), the Global Volcanism Program (GVP) of the Smithsonian Institution's National Museum of Natural History, and the International Association for Volcanology and Chemistry of the Earth's Interior (IAVCEI).
