[H-DS10] Geohazards in humid, tectonically active countries and their precursors

Sat. Jun 5, 2021 5:15 PM - 6:30 PM Ch.10

convener:Satoru Kojima(Department of Civil Engineering, Gifu University), Taro Uchida(University of Tsukuba), Yoshihiko Kariya(Department of Environmental Geography, Senshu University)

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.
