Cascading River Hazards from Seismic and Tropical Cyclone Triggered Landslides in Taiwan

This talk focuses on cascading river hazards in Taiwan generated by landslides triggered by earthquakes and tropical cyclones. Drawing on case studies from Typhoon Morakot and the 2024 Hualien earthquake, I explore how sediment pulses move through river systems, reshaping channels and sustaining hazard long after the initial event. Together, these examples show how extreme events can produce lasting and evolving impacts in steep landscapes.
