[H-DS08] Landslides and related phenomena

Fri. May 29, 2026 9:00 AM - 10:30 AM Exhibition Hall Special Setting (3) (Exhibition Hall 7&8, Makuhari Messe)

Chairperson:Wang Gonghui(Disaster Prevention Research Institute, Kyoto University), Chigira Masahiro(Fukada Geological Institute), Imaizumi Fumitoshi(Faculty of Agriculture, Shizuoka University), SAITO Hitoshi(Graduate School of Environmental Studies, Nagoya University)

Landslides, rockfalls, debris flows, and other types of mass movements occur worldwide and have caused severe disasters throughout history. In particular, countries in Asia, including Japan, experience significant damage from these events almost every year. Research on mass movements has been conducted across a wide range of disciplines, such as geomorphology, geology, geophysics, erosion and sediment control engineering, and geotechnical engineering. However, further advances in understanding and societal contributions can only be achieved through interdisciplinary discussions that bridge these fields.
This session aims to provide a platform for presenting and discussing the latest research related to mass movements, with the overarching goal of deepening scientific understanding and contributing to disaster risk reduction. Topics of focus will include, but are not limited to: new insights into failure mechanisms, advances in monitoring and observation techniques, development and refinement of predictive methods, slope stabilization and hazard control measures, and approaches to hazard and risk assessment.
