1. They typically occur on steep slopes in mountainous regions
2. They involve the movement of rock fragments of various sizes, from small stones to massive boulders
3. They can be triggered by several factors including:
- Heavy rainfall or snowmelt that weakens the soil
- Earthquakes that destabilize the slope
- Freeze-thaw cycles that crack rocks
- Human activities like mining or road construction
- Erosion that undermines support for rocks above
Rockslides can be extremely dangerous, moving at high speeds and carrying enormous destructive force. They can block roads, damage infrastructure, dam rivers (potentially causing flooding), and pose serious threats to people in their path.
In mountainous regions, rockslides are a natural part of the erosion process that gradually reshapes the landscape over time.
