Rockfall

A rockfall occurs when rocks or fragments detach from a steep or rocky surface, such as a cliff or mountainside, and rapidly fall down due to gravity. This natural process can be triggered by weathering, freeze-thaw cycles, natural vibrations, or earthquakes, weakening the rock's stability. Rockfalls pose hazards to roads, trails, and structures below, requiring monitoring and mitigation to reduce risk. They are a common part of mountain and cliff erosion, shaping landscapes over time, but can be sudden and potentially dangerous when occurring unexpectedly.
