Causes of Landslides
Landslides can be caused by poor ground conditions, geomorphic
phenomena, and natural physical forces and quite often due to
heavy spells of rainfall coupled with impeded drainage.
A Checklist of Causes of Landslides
Ground Causes
| • |
Weak, sensitivity,
or weathered materials
|
| • |
Adverse ground structure
(joints, fissures etc.)
|
| • |
Physical property variation
(permeability, plasticity etc)
|
Morphological Causes
| • |
Ground uplift
(volcanic, tectonic etc)
|
| • |
Erosion (wind, water)
|
| • |
Scour4. Deposition loading
in the slope crest5. Vegetation removal (by forest fire, drought
etc)
