What is varnes classification?
VARNES´ CLASSIFICATION OF SLOPE MOVEMENTS Falls are abrupt movements of. masses of geologic materials, such as rocks and boulders, that become detached from steep slopes or cliffs.
What are the three natural causes of landslide?
Landslides are caused by disturbances in the natural stability of a slope. They can accompany heavy rains or follow droughts, earthquakes, or volcanic eruptions. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris.
What is landslide PDF?
A landslide occurs when stability conditions of the slope is disturbed either by the increase. of stress imposed on the slope and / or by the decrease in strength of the earth material. building up the slope and it involves enmass downward movement of earth material under. the influence of gravity.
What is topple landslide?
Topples. Topple failures involve the forward rotation and movement of a mass of rock, earth or debris out of a slope. This kind of slope failure generally occurs around an axis (or point) at or near the base of the block of rock. A good example of a site experiencing topple failures is Aldbrough, UK.
What is landslide PPT?

What are the 6 types of landslide?
Types of Landslides These include falls, topples, translational slides, lateral spreads, and flows.
What are the 5 types of landslides?
Landslides in bedrock
- Rock falls. Single and small rock falls from cliffs build up to form aprons of scree or talus, sometimes developing over long time periods.
- Rock slope failures. This group of landslides varies greatly in features.
- Rotational landslides.
- Debris flows.
- Creep.
- Solifluction.
- Translational slides.
What is the most human activity that triggers landslide Why?
Construction works, legal and illegal mining, as well as the unregulated cutting of hills (carving out land on a slope) caused most of the human-induced landslides.
How do human activities trigger landslide?
Yes, in some cases human activities can be a contributing factor in causing landslides. They are commonly a result of building roads and structures without adequate grading of slopes, poorly planned alteration of drainage patterns, and disturbing old landslides.
