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.

Preliminary field report of landslide hazards following Hurricane Helene Preliminary field report of landslide hazards following Hurricane Helene
Executive SummaryThis report reflects our knowledge regarding the widespread landslide activity associated with Hurricane Helene observed during the U.S. Geological Survey’s (USGS) mission assignment to North Carolina in October 2024. The material in this report was originally prepared for the Federal Emergency Management Agency under mission assignment DR-4827-NC. The data and...
Constraining landslide frequency across the United States to inform county-level risk reduction Constraining landslide frequency across the United States to inform county-level risk reduction
Informative landslide hazard estimates are needed to support landslide mitigation strategies to reduce landslide risk across the United States. Whereas existing national-scale landslide susceptibility products assess where landslides are likely to occur, they do not address how often, which is a critical element of landslide hazard and risk assessments. In particular, the U.S. Federal...
Uncertainty reduction for subaerial landslide-tsunami hazards Uncertainty reduction for subaerial landslide-tsunami hazards
Subaerial rock slopes may generate a tsunami by rapidly moving into the water. Large uncertainty in landslide characteristics propagates into large uncertainty in tsunami hazard, making hazard assessment more difficult for land and emergency managers. Once a potentially tsunamigenic landslide is identified, it may not be clear which landslide characteristics contribute most significantly...

Brights Creek, North Carolina
The USGS and its cooperators at the North Carolina Geological Survey have installed instruments in a steep hillside at Brights Creek, approximately 15 km east of Hendersonville, North Carolina. Data collection at this site supports research on hydrologic factors that control landslide initiation and is provided here for situational awareness before and during major storm events.
Shumont Mountain, North Carolina
The USGS and its cooperators have installed instruments in a steep hillside at Shumont Mountain, approximately 4 km north of Chimney Rock, North Carolina . Data collection at this site supports research on hydrologic factors that control landslide initiation and is provided here for situational awareness before and during major storm events.
