USGS Imagery assessment of landslide extent and severity (as of 07/01/26, 4:30 PM MDT). Verification remains ongoing. Color is based on USGS’s remote assessment. Landslide impact is classified as “Unknown” (yellow), “Minor or none” (green), “Localized” (orange), or “Major or Widespread” (purple).

Large landslide on the southwest side of Mt. King George. The main debris lobe is 1800 m wide, and material would have travelled approximately 6 km from the source area (triangular scar) in the background. Photo courtesy of Yukon Geological Survey.

The 2025 Matai’an landslide in eastern Taiwan represents the largest landslide event ever recorded in the region and initiated a cascading hazard sequence involving landslide-dam formation and repeated dam-breach floods.

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.

Postfire debris flows pose a hazard to human life, property, and infrastructure when they travel from steep source areas to urbanized alluvial fans or other developed areas.

A debris flow recorded by a USGS Landslide Monitoring Station in the 2024 Elk Fire burn area near Dayton, Wyoming. The flow was triggered by intense rainfall during a thunderstorm on the evening of July 15, 2025.
