Landslide Hazards Program
The primary objective of the National Landslide Hazards Program is to reduce long-term losses from landslide hazards by improving our understanding of the causes of ground failure and suggesting mitigation strategies.

Multi-site evaluation of a postfire debris-flow runout forecast method Multi-site evaluation of a postfire debris-flow runout forecast method
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. Existing methods for rapid (
Landsliding follows signatures of wildfire history and vegetative regrowth in a steep coastal shrubland Landsliding follows signatures of wildfire history and vegetative regrowth in a steep coastal shrubland
Five years after the deadly and destructive 9 January 2018 Montecito debris flows (Santa Barbara County, California, USA), an atmospheric river storm on 9 January 2023 triggered widespread landsliding that affected many of the same drainages in the Santa Ynez Mountains. Using high-resolution aerial imagery, we identified >10,000 landslides over an ∼160 km2 area. Most of the landslides...
Dynamic feedbacks between river meandering and landsliding in northwestern Washington glacial terraces Dynamic feedbacks between river meandering and landsliding in northwestern Washington glacial terraces
Landsliding in river valleys poses unique risks for cascading hazards and can damage infrastructure and cause fatalities. In postglacial valleys, many landslides are posited to occur in relation to lateral river erosion, but the dynamics of fluvial-hillslope interactions are not well understood. Here, we investigate a section of the Nooksack River in western Washington State where the...

2026 Nepal Debris Avalanche and Flash Flood
On Wednesday morning (local time), 26 August 2026, a catastrophic debris flow and flood was likely triggered by rapid slope failure involving a glacier in Lāṅṭāṇ National Park, Nepal, near the border with China. This debris flow and flooding travelled nearly 100 km and impacted populated areas downstream along the Lende Kholā and Trishuli̇̄ Kholā rivers, including the Rasuwāgaḍhi̇̄ border post...

2026 Venezuela Sequence Earthquake-Triggered Landslide Hazards
On Wednesday, June 24th, 2026, a pair of earthquakes of Magnitude 7.2 and Magnitude 7.5 occurred in northern Venezuela, west of Caracas. The U.S. Geological Survey (USGS) Ground Failure product estimated that landslides triggered by this earthquake would likely be significant in number and/or spatial extent. This landslide event page serves to communicate timely science information to our partners...
