| Session Description | Catastrophic landslides frequently occur in high mountain areas, especially in active tectonic regions, impacting on lives and the earth’s surface ecosystem. Extensive researches attempted to explore the temporal occurrence, spatial distribution, triggering mechanisms and kinematics of historic cases. Meanwhile, lots of attention also paid on predicting the susceptibility, magnitude and social impact of potentially large landsliding. However, increasing the knowledge about the phenomena related to catastrophic landslides is still urgent either from the hazard mitigation or scientific view point. This session calls for presentations of large landslide researches, especially on: 1. Field investigation and recognition of types of catastrophic landslides. 2. Mechanism for earthquake and rain triggering catastrophic landslides, including liquefaction of surface deposits, dramatic high-velocity weakening of rock interfaces like bedding planes. 3. Recent advances on laboratory tests and new findings that contribute to the study of catastrophic landslides. 4. Numerical simulation of landsliding, transportation, deposition, and growth of catastrophic debris flow from shallow landslides. 5. Historic case with focus on the temporal or spatial occurrence of catastrophic landslides. 6. Monitoring and prediction of the potentially occurrence of catastrophic landslides, its consequence, and disaster mitigation measure. |
