Landslides and extreme weather
Conveners : Hiroshi Fukoka ; Gabriele Scarascia Mugnozza
Session description :
Most landslides are associated with heavy rainstorms, while the frequency of extraordinary severe rainfall events associated with numerous landslides are apparently increasing in most countries for these decades. This session is devoted to the advances in mechanism, mapping and hazard assessment of landslides induced by extreme weather conditions. Topics include recent developments in regional and global monitoring of precipitation, based on ground-based radar network and satellite sensors, enables larger area landslide prediction and early warning when combined with regional or global databases of various geophysical properties. On the other hands, field observations, laboratory experiments, and numerical simulation have provided various aspects of landslide dynamics, this session will present papers focusing on empirical, probabilistic or hydrological models of landslide triggered by rainfall. This session also focuses on predictions of landslide location, size and time of failure, magnitude-frequency relationship, and assessment of the run out area, which are important indicators for improved hazard and risk mitigation.
