Ground instabilities such as landslides, subsidence, sinkholes, and soil liquefaction are highly sensitive to climate change. In Italy, these phenomena represent a major component of hydrogeological risk, particularly in mountainous and hilly regions where recent extreme events have highlighted the growing influence of climatic stressors on slope instability. Intense and prolonged rainfall acts both as a preparatory factor, gradually weakening slopes, and as a triggering factor, directly inducing failures. Despite the increasing frequency and severity of rainfall extremes, a comprehensive conceptual framework integrating extreme precipitation behaviour into landslide dynamics is still lacking.
