Hokkaido, Japan, 29 May-5 June 2020
On behalf of Commission on the Chemistry of Volcanic Gases (CCVG) of the International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI), we are delighted to invite the international geochemical community working on volcanic gases to participate the 14th CCVG Workshop in Hokkaido, Japan, from 29 May to 5 June 2020.

Main aims of the workshop are to share and discuss recent developments in observation techniques, results, and interpretations of volcanic gas studies. Three core activities of the workshop will be composition and flux measurements using direct sampling and remote sensing techniques inactive vents, plume, and soil emissions. The workshop will include two days of scientific presentations and discussions followed by three days of field observations. Measurements will be carried out at Usu, Tarumae, and Tokachi volcanoes.

Pre-workshop observations, mainly devoted to plume measurements using remote sensing techniques, will be offered as an option and will take place at Asama volcano in Central Japan from 26 to 29 May 2020. The excursion includes one day of field work at the volcano and one spare day in case of bad weather conditions.

Registration and Abstract submission will open in November 2019, along with release of the Third Circular to provide detailed information on costs and eventual grant options, as well as deadlines. All information will be made available through the website, here.
