The project will examine landslide reoccurrence in southwestern Pennsylvania and its interaction with human landscape modifications. By analyzing regional landslide data and conducting spatial analysis, the project seeks to identify patterns and develop mechanistic models of reoccurrence. Multivariate analysis will compare environmental factors between reoccurring and stable/new landslides. The results will identify high-risk areas, guiding mitigation efforts and informing effective repair methods in landslide-prone areas.
