AZGS Document Repository: Building a Statewide Inventory of Landslides in Arizona. “Landslides in Arizona are an under-appreciated geologic hazard. Prior to this project, the nature and extent of landslides was limited to an incomplete array of geologic maps and reports. To address this knowledge and data gap, the Arizona Geological Survey (AZGS) initiated a Landslides Hazards Program. Working with our partner agency, the Arizona Division of Emergency and Military Affairs (DEMA), we compiled the first comprehensive landslide inventory for the State of Arizona.” The freely-available document attached to this page is a PDF, but includes links to the online database.
