Question

What methods are used to monitor landslides?

Answer 1

Various methods are used to monitor landslides, including:

1. Ground-based monitoring: This involves installing sensors, such as inclinometers and piezometers, to measure ground movement and water pressure within slopes.
2. Remote sensing: Techniques like satellite imagery, LiDAR, and aerial surveys are used to monitor changes in land surface features that may indicate potential landslides.
3. Seismic monitoring: Seismometers can detect ground vibrations caused by landslides, providing early warning signals.
4. Weather monitoring: Monitoring weather conditions like rainfall intensity can help predict landslide events triggered by heavy precipitation.
5. Geotechnical instrumentation: Instruments like extensometers, tiltmeters, and GPS devices are used to measure ground deformation and movement in landslide-prone areas.
