[S-VC33] Monitoring and assessment of volcanic activities

Fri. May 26, 2023 10:45 AM - 12:00 PM 303 (International Conference Hall, Makuhari Messe)

convener:Akimichi Takagi(Meteorological Research Institute, Japan Meteorological Agency), Hiroshi Munekane(Geospatial Information Aurhotiry of Japan), Takao Ohminato(Earthquake Research Institute, Tokyo University), Chairperson:Akimichi Takagi(Meteorological Research Institute, Japan Meteorological Agency), Akihiko Terada(Volcanic Fluid Research Center, Tokyo Institute of Technology)

Volcanism is a natural phenomenon that sometimes causes disasters, but volcanology is not yet at the stage of reliably predicting its sequence. In order to better understand the mechanism of volcanic activity and enable prediction of its sequence in the future, this session will review the current state of volcanic monitoring and discuss how volcanology and technology can contribute to activity assessment. The subjects are volcanic monitoring technology, analysis technology for contributing to activity evaluation, and case studies that contribute to the interpretation of volcanic activity. We also welcome monitoring cases at individual volcanoes.
