National Landslide Preparedness Act Reauthorization Act of 2025

National Landslide Preparedness Act Reauthorization Act of 2025

This bill renews and continues a federal program focused on helping the United States better understand, prepare for, and respond to landslides. Originally established under the National Landslide Preparedness Act, the program coordinates efforts across multiple government agencies — primarily through the U.S. Geological Survey (USGS) — to improve landslide science, early warning systems, and hazard maps. By reauthorizing the program, Congress is essentially giving it a fresh mandate and continued funding to keep this work going.

The bill supports activities like creating more detailed maps that show which areas of the country are at higher risk for landslides, developing better tools to warn communities before a landslide occurs, and funding research to improve our overall understanding of how and why landslides happen. It also encourages coordination between federal agencies, state and local governments, universities, and other partners to share information and build expertise.

The people most directly affected are those who live in landslide-prone regions, which include large parts of the Pacific Coast, Appalachia, Alaska, and other mountainous or hilly areas across the country. State and local emergency managers, land-use planners, and transportation officials would also benefit from improved data and tools to make safer decisions about roads, buildings, and communities in vulnerable areas. Researchers and universities involved in earth sciences may also see continued grant and partnership opportunities through the program.

The bill passed the Senate by unanimous consent, meaning no senators objected, suggesting broad bipartisan support. It has been sent to the House, where it is awaiting further action.
