Landslides

Landslides are a geological event where large portions of ground break loose and slide down a slope. they can cause large amounts of damage, and are generally quite dangerous.

What are signs and warnings for landslides?

Signs and Warnings

If your house is on a hill, you can detect possible slope

failure if you watch for these signs:

  1. Doors or windows stick or jam for the first time.
  2. New Cracks appear on plaster, tile, brick or foundations.
  3. Outside walls, walks or stairs begin pulling away from the building.
  4. Slowly developing, widening cracks appear on the ground or on paved areas such as streets or driveways.
  5. Underground utility lines break.
  6. Fences, retaining walls, utility poles or trees tilt or move.
  7. Water or bulging ground appears at the base of a slope.

How do landslides form?

While gravity and friction will hold loose material, cohesion within rock surfaces is also important. Anything that reduces the friction (such as water), or reduces cohesion (such as a tremor) or adds potential energy (more rock, structures, people, vehicles) can cause the material to slide downhill over the underlying material.

When stress is greater than strength,the slope becomes unstable and slope failure may occur. A landslide is a kind of slope failure.

What causes landslides?

Essentially, a landslide results from the failure of soil and rock on hillsides to remain securely in place, as for one reason or another, they lose cohesion. Another major force is gravity. Gravity causes stress for slope materials such as rocks and soil, because it is constantly acting to try to pull the materials downslope.

Any of the following factors can contribute to landslides:

  • Tree clearing and deforestation: with fewer trees and tree roots to secure the soil, landslides can more easily occur.
  • Earthquakes: earth tremors can destabilise hillsides.
  • Excessive rainfall: super-saturated soils can not hold up against gravity.
  • Use of landfill to build up hillsides and roadways: landfill is not a stable as solid ground or rock.
  • Mining activities, quarrying and excavation: blasting causes vibrations which can have the same effect as eartquakes and tremors, while undermining a slope causes instability.
  • Drought: drier soil is less cohesive than damp soil.

How does deforestation help to cause landslides?

Trees and plants form root systems in the soil. These roots act like nets, helping to hold the soil in place. The roots, along with shade from the trees, also keep the soil moist and healthy so that it can absorb and drain lots of water. When trees and plants get cut down, those root systems die and decompose. The soil dries out and becomes very loose. Then, when a very heavy rain falls, the soil can wash away in a mudslide. This is most likely to happen where the ground is steep, like on the side of a hill or small mountain.
On a slope, tree roots help to hold the land together and pin it to the solid ground well below the surface.

Mass movement is a slow process in the formation of creep.

What are landslides?

Landslides are a mass of moving rocks, debris and soil. Landslides can occur in any area, although some areas are more prone to landslides (for example: California).

A landslide can occur when the force of gravity overcomes the force of friction that holds a sloped mass in place. A landslide could be triggered by the movement created by an earthquake, or simply from saturation by rainfall or other moisture sources.

How are earthquakes landslides tsunamis and plates all related?

Tsunamis and plates are some what related in one way tsunamis are related by the change in the earths epicenter. a landslide is related in two ways by an focus and a fault line. plates are related an forming of mountains and the turning of the types of plates.

Plates shifting causes earthquakes which can cause landslides or tsunamis.

What is the difference between a landslide and mudflow?

A landslide is the most destructive type of mass movement, and a mudflow is the rapid movement of a mixture of water, rock, and soil.

Why landslides occur during rainy season?

The main reason is that when the soil gets water logged it gets heavier. As the top layer gets soaked it will be more prone to slip on what's underneath, it it's on a slope.

Another reason is that water can weaken the force that holds the soil together, again making it more prone to slip. Yet a third is if you get running water cutting channels in the soil, whic will pull chunks and blocks away with it.

What determines the difference between a creep and a landslide?

Generally the speed at which the objects travel and the conclusion of the movement. A creep is an almost unnoticed, slow or gradual approach. It allows for the movement to be contained if necessary. A landslide can be a sudden falling of rock or any other detritus on or from a steep slope and is a dangerous occurrence. It can overwhelm whatever lies in its path.
