What counts as a landslide warnings
Landslide and mudslide warnings follow rainfall thresholds on steep terrain, and are issued by geological surveys, road authorities or civil protection. They are strongly local: a slope can fail while the next valley is unaffected. Deforested hillsides, burn scars and construction sites raise the risk sharply.
