A Conceptual Event-Tree Model for Coseismic Landslide Dam Hazard Assessment

, 2014
peer reviewedAbstract Earthquakes may trigger a series of multiple cascading geohazard phenomena. For example, coseismic landslides may block rivers and form landslide dams, which occur frequently in tectonically active mountains with narrow and steep ...

Limits to coseismic landslides triggered by Cascadia Subduction Zone earthquakes

Geomorphology, 2022
Landslides are a significant hazard and dominant feature throughout the landscape of the Pacific Northwest. However, the hazard and risk posed by coseismic landslides triggered by great Cascadia Subduction Zone (CSZ) earthquakes is highly uncertain due ...

Evaluation of coseismic landslide susceptibility by combining Newmark model and XGBoost algorithm. [PDF]

PLoS One
Coseismic landslides are among the most perilous geological disasters in hilly places after earthquakes. Precise assessment of coseismic landslide susceptibility is crucial for forecasting the effects of landslides and alleviating subsequent tragedies. This research formulates a comprehensive landslide hazard assessment model by integrating the Newmark

On the Dynamic Fragmentation and Lubrication of Coseismic Landslides [PDF]

Journal of Geophysical Research: Solid Earth, 2018
AbstractThe three‐dimensional discrete element method has been employed to analyze the dynamic fragmentation and lubrication mechanisms of coseismic Tangjiashan landslide induced by the 2008 Ms 8.0 Wenchuan earthquake. The numerical results show that the internal rock damage occurs and propagates gradually along the basal failure plane due to seismic ...
