[H-DS14] Geohazards in humid, tectonically active countries and their precursors

Mon. May 27, 2019 10:45 AM - 12:15 PM 106 (1F)

convener:Masahiro Chigira(Disaster Prevention Research Institute, Kyoto University), Hiroshi YAGI(Faculty of Art, Science and Education, Yamagata University), Satoru Kojima(Department of Civil Engineering, Gifu University), Taro Uchida(National Institute for Land and Infrastructure Management), Chairperson:Satoshi Ishimaru

This session covers mass movements of landslide, slope failure, debris flow, and gravitational slope deformation in tectonically active, humid countries, and aims to discuss on their mechanisms, characteristics of occurrence sites, the significance in geological time scale, and the methodology to mitigate their affects by researchers with various related research fields. In particular, papers about 2017 northern Kyushu rainstorm, 2018 Osaka earthquake, 2018 Western Japan rainstorm, and 2018 Hokkaido earthquake are welcome
