“Landslides are a damaging, disruptive, and potentially deadly geologic hazard. While landslides occur in every U.S. State, their impacts are often a localized and episodic phenomenon, plus landslide types and triggering mechanisms vary widely across the country. Looking at past incidents help us to understand and prepare for landslides, but information about historic landslide events varies in quality, availability, and extent. This makes it hard to get a clear picture of landslide risks across the entire country. To improve this, the U.S. Geological Survey (USGS) studies landslide activity, compiles information about past landslides, and develops tools to predict where landslides might happen in the future. In particular, the two products described and linked here in our interactive online map are the national landslide inventory compilation (Mirus et al., 2020) and the national landslide susceptibility map (refer to Mirus et al., 2024)…Landslide inventories are collections of data about where landslides have occurred and may include other important details. This information on where they occur is essential for scientific research on landslides, as well as risk reduction efforts. Different agencies and groups keep their own landslide records, often in various formats and within specific regions, making it hard to get a complete picture. To address this, the USGS has created a nationwide landslide inventory and made it available online through an interactive map. This map includes digital data from both USGS and other sources, all formatted in a consistent..”
