A landslide is the mass movement of rock, soil, and debris down a slope due to gravity. It occurs when the driving force is greater than the resisting force.It is a natural process that occurs in steep slopes. The movement may range from very slow to rapid. It can affect areas both near and far from the source.
Landslide materials may include:
- Soil
- Debris
- Rock
- Garbage
- Natural triggers
- Intense rainfall
- Weathering of rocks
- Ground vibrations created during earthquakes
- Volcanic activity
- Man-made triggers
Movement can occur in many ways. It can be a fall, topple, slide, spread, or flow.
