Hurricane Helene Landslide Hazard Map
What it measures. Maps where landslides and debris flows were most likely during Hurricane Helene, based on how much rain fell in early October 2024.
How it's made. Produced by the U.S. Geological Survey using rapid landslide-hazard computer models driven by early rainfall estimates.
How & where you'd use it. Gave emergency teams early awareness of the most dangerous areas and helped plan ground reconnaissance.

Official description
The two modeling approaches used were adapted from existing models and were run in early October 2024 using initial precipitation estimates to produce rapid event-specific landslide hazard estimate maps. These preliminary maps were initially released provisionally to meet the need for timely best science during the emergency response (version 1.0). The outputs were used to provide early situational awareness of what areas may have been more severely impacted by landslides and debris flows. These results were also used in planning reconnaissance.
