[S-VC47] [JJ] Active volcanism

Tue. May 23, 2017 1:45 PM - 3:15 PM Convention Hall A (International Conference Hall 2F)

convener:Yuta Maeda(Nagoya University), Yosuke Aoki(Earthquake Research Institute, University of Tokyo), Chairperson:Hiroshi Ichihara(Kobe University), Chairperson:Yuki Suzuki(Department of Earth Sciences, Faculty of Education and Integrated Arts of Sciences, Waseda University)

This session discusses various phenomena associated with active volcanisms including, but not limited to, geophysical and geochemical observations, geology, historical eruptions, and development of modern instruments. We also welcome contributions on recent eruptions.
