Subject: COV10 Session S1.33 Volcanic Degassing: Insights into Volcanic Processes, Impacts and Hazard
***************************************************************************************************************
Dear Colleagues,
We would like to announce the Session - S1.33 Volcanic Degassing: Insights into Volcanic Processes, Impacts and Hazard - at the next Cities on Volcanoes conference held in Naples (Italy) from 2 - 7 September 2018. For more information on the conference, please visit:http://www.citiesonvolcanoes10.com
The deadline to submit abstracts is 10 May 2018. For further information, please feel free to contact the conveners.
Session description:
Volcanoes release gas, ash and aerosols particles into the atmosphere during explosive episodes and quiescent stages from vents, fumarole and soil diffuse degassing. Understanding gases dissolved in magma, and measuring their emissions is crucial to characterising states of unrest and evaluates impacts on health, atmospheric composition and the environment. Ranging from astonishing plume emissions to silent exhalation through soils, volcanic degassing exerts a dominant role in forcing the timing and nature of unrests and volcanic eruptions. Volcanogenic emissions have strong impacts on the Earth’s radiation budget and climate over a range of temporal and spatial scales. Sulphate may lead to global dimming and a decrease in Earth’s surface temperatures for years, similarly halogens can perturb the troposphere causing depletion of stratospheric ozone layer. Direct and indirect gas effects may also impact on local-to-regional air quality seriously affecting biosphere and environment, and the continuous release of gas from soil may pose long-term health-hazards in both outdoor and indoor environment. Gases are measured and monitored via a range of direct-field, remote sensing and laboratory sampling techniques, such as to gain insights into both subterranean-surface processes and the extent of real-time and time-averaged volcano’s impacts in concert with geophysical data and modelling. This session focus 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 contribution discussing how we go from observations to synoptic understanding of volcanic processes and their impacts.
We hope you consider submitting an abstract and attending the conference.
Sincerely,
Giuseppe Salerno, Carlo Cardellini, Fàtima Viveiros, Pasquale Sellitto, Andrew MCGonigle ad Franco Tassi
