[H-DS07] Landslides and related phenomena

Tue. May 24, 2022 1:45 PM - 3:15 PM 201B (International Conference Hall, Makuhari Messe)

convener:Masahiro Chigira(Fukada Geological Institute), convener:Gonghui Wang(Disaster Prevention Research Institute, Kyoto University), Fumitoshi Imaizumi(Faculty of Agriculture, Shizuoka University), Chairperson:Fumitoshi Imaizumi(Faculty of Agriculture, Shizuoka University)

Landslides, such as rockslides, rockfalls, and debris flows, have been occurring extensively in a large number of countries, typically Asian countries, causing heavy damage. Landslides have been studied in various research fields, such as geomorphology, geology, geophysics, Sabo engineering, geotechnics, but we need a common platform to exchange research results and make discussion to strengthen our activity. This session is such a place and we invite contributions that report and discuss on landslides and related phenomena, focusing on improved understanding of their characteristics; new insights into landslide mechanisms; the development of new approaches to monitoring; novel approaches to behavior forecasting and prediction; studies of successful landslide management; and the development of methods for hazard and risk evaluation.
