AZGS geologists Ann Youberg and Joe Cook compiled a database of more than 8,000 landslide features observed in Arizona as part of the Arizona Statewide Landslide Inventory Database (AzSLID) program. The data are available to scrutinize and download at the interactive Natural Hazards of Arizona Viewer - http://uagis.maps.arcgis.com/apps/webappviewer/index.html?id=98729f76e46... .
This map shows the distribution of all identified landslide features (red) and a severely underrepresented sampling of debris flows (yellow).
