4-4-4-4-4-4-4-4-4-4-4-4-4 From: Iona McIntosh <i.m.mcintosh@xxxxxxxxxxxxx> Dear Colleagues, We would like to draw your attention to the following session on magmatic timescales at the 2020 JpGU-AGU Joint Meeting. The abstract submission deadline is Feb 18th at 17:00 JST, and the meeting will be held in Chiba, Japan (close to Tokyo) from May 24th â?? 28th. We look forward to your contributions! *S-VC41 â?? Timescales of magmatism: from genesis to eruption* Scope: Magmatic processes are known to operate across a range of timescales: from thousands to millions of years' residence and evolution within a magmatic plumbing system, through to the hours to minutes prior to eruption. Understanding the timescales of these magmatic processes, including accumulation, ascent, eruption, and final cessation of activity is vital for interpreting and responding to future magmatic activity. Together with thorough dating of deposits that reveal the timing and frequency of past eruptions, this knowledge provides the foundation for improved hazard management in volcanic regions. By using a range of petrological, geophysical, geochemical and geochronological tools, increasingly detailed timescale constraints can be placed on past eruptive episodes. In this session we invite submissions that examine magmatism and volcanism across a variety of timescales; from residence and rejuvenation within the crustal column to eruptive triggering mechanisms and syn-eruptive processes, and their relation to the long-term timing and frequency of repeated activity. Invited speakers: Weiran Li (Earth Observatory of Singapore) Shumpei Yoshimura (Hokkaido University) Conveners: Katy Chamberlain (University of Derby) Iona McIntosh (JAMSTEC) Kenichiro Tani (National Museum of Nature and Science) Akihiko Tomiya (Geological Survey of Japan) 4-4-4-4-4-4-4-4-4-4-4-4-4 ============================================================== 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).
