crolli

Crolli is the Italian plural noun derived from crollo, meaning collapse or fall. In geology and geomorphology, crolli designate mass-wasting events in which rock, soil, or debris detaches from a hillside and moves downslope under gravity. The term is used broadly to describe natural slope failures and, in civil engineering, failures of engineered structures.

These events range from small rockfalls to large landslides and debris flows. They can be sudden or gradual and may be triggered by factors such as heavy rainfall, rapid snowmelt, earthquakes, freeze-thaw cycles, or human activities that destabilize slopes.

Crolli pose hazards to life and infrastructure. Hazard assessment relies on field observations, historical records, rainfall thresholds, geological mapping, and remote sensing, while early warning systems employ sensors, rainfall data, and slope-stability models to evaluate risk and guide mitigation.

Crolli is also an Italian surname. It is relatively uncommon and has been recorded in Italian genealogical sources; the etymology is not always clear but it most likely reflects a toponymic or descriptive origin. Individuals bearing the name have appeared in regional contexts in Italy.
