Abstract
No existing research provides an integrated analysis of the key parameters that contribute to long-runout landslides in the Western United States. This study begins the task by assembling a dataset of geological, topographical, and hydrological parameters for landslides from eight study areas. Six measures of mobility were analyzed and two (landslide height drop to runout length ratio, H/L and landslide runout length, L) were selected for further use. Analysis of the correlations of the measured parameters with H/L and L was performed to quantify how well they predict these two mobility measures. The initial slope angle was found to match H/L for small landslides that did not experience a break in slope. Landslides in concave topography, landslides on previously moved material, and landslides in confined topography were found to possess lower H/L values, indicating higher mobility. Finally, landslides occurring on previously moved material and landslides in confined topography were found to possess larger values of L.
