Landslide Hazards - Maps | U.S. Geological Survey - USGS.gov
We used aerial photos, topographic maps, LiDAR data, satellite images, and field ob. This report presents a preliminary map of landslide deposits in the Mesa Verde National Park area (see map sheet) at a compilation scale of 1:50,000.
In any type of landslide hazard assessment, there is a need to consider topography and other factors that influence the propensity to landslide activity (susceptibility factors), as well as landslide triggering factors (precipitation, earthquakes, human activity).
