Landslide Monitoring
Loose sediment, rocks and weathered material usually remain stationary and stable on a slope. However, matter can be disturbed naturally by earthquakes or heavy rainfall, or by human activity such as road construction. When disturbed, the debris is pulled down by gravity and, with water acting as a lubricant, a landslide is created. The damage can be disastrous — wiping out communications networks or causing damage to life and property — but the good news is that, unlike other geological...
