Accurate and accessible information about landslides is essential for understanding slope instability, reducing economic losses, and preventing fatalities across Alaska. In response to recent catastrophic events, the State of Alaska established the Landslide Hazards Program within the Division of Geological & Geophysical Surveys (DGGS) to assess and communicate landslide risks. A central initiative of this program is the Alaska Landslide Inventory (ALI), a geospatial database that compiles both published and newly identified landslides. By classifying events by movement type and including metadata such as event date, kinematic features, and confidence levels, the ALI provides a critical resource for planners, emergency managers, researchers, and policymakers. This evolving database helps identify landslide-prone areas and supports informed decision-making for hazard mitigation and land-use planning.
