Quick Answer: What Is Landslide And Its Effects?

What is landslide and its causes and effects?

Abstract.

Landslides can cause seismic disturbances; landslides can also result from seismic disturbances, and earthquake-induced slides have caused loss of life in many countries.

Slides can cause disastrous flooding, particularly when landslide dams across streams are breached, and flooding may trigger slides..

What is landslide and its types?

TYPES OF LANDSLIDES. The term “landslide” describes a wide variety of processes that result in the downward and outward movement of slope-forming materials including rock, soil, artificial fill, or a combination of these. The materials may move by falling, toppling, sliding, spreading, or flowing.

What is landslide disaster?

Landslides occur when ground on slopes becomes unstable. The unstable ground collapses and flows down the side of a hill or mountain, and can consist of earth, rocks, mud and any debris which may be caught in its wake. If a landslide occurs near inhabited areas, it can cause a great deal of damage.

What are the 3 causes of earthquakes?

Causes of Earthquakes in GeneralInduced Earthquakes. Induced quakes are caused by human activity, like tunnel construction, filling reservoirs and implementing geothermal or fracking projects.Volcanic Earthquakes. Volcanic quakes are associated with active volcanism. … Collapse Earthquakes.

What causes a 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 the harmful effects of landslides?

The impact of a landslide can be extensive, including loss of life, destruction of infrastructure, damage to land and loss of natural resources. Landslide material can also block rivers and increase the risk of floods.

What are the 10 causes of earthquake?

Things that cause earthquakesGroundwater extraction – decrease in pore pressure.Groundwater – increase in pore pressure.Heavy rain.Pore fluid flow.High CO2 pressure.Building dams.Earthquakes.No earthquakes (Seismic quiescence)More items…•

What are the causes and effects of earthquakes?

The environmental effects of it are that including surface faulting, tectonic uplift and subsidence, tsunamis, soil liquefaction, ground resonance, landslides and ground failure, either directly linked to a quake source or provoked by the ground shaking.

How can landslides be prevented?

To prevent shallow slides, you can do a few things on slopes that are on your property:Maintain as much vegetation as possible on the slope to help retain the soil.Do not put yard waste on the slope.Do not add additional water from downspouts to slopes from storm water runoff being directed to a hillside.More items…•

What should we do when landslide occurs?

What to Do if You Suspect Imminent Landslide DangerContact your local fire, police, or public works department. Local officials are the best persons able to assess potential danger.Inform affected neighbors. … Evacuate. … Curl into a tight ball and protect your head if escape is not possible.

What are the two types of landslides?

Landslides in bedrockRock 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.

How do landslides affect the environment?

Landslides can overwhelm, and even pollute streams and waterbodies with excess sediment. In extreme cases they can dam streams and rivers, impacting both water quality and fish habitat. Landslides can wipe out large tracts of forest, destroy wildlife habitat, and remove productive soils from slopes.

What are the 4 types of landslides?

Landslides are part of a more general erosion or surficial pro- cess known as mass wasting, which is simply the downslope movement of earth or surface materials due to gravity. They are classified into four main types: fall and toppling, slides (rotational and translational), flows and creep.

What are the human activities that causes landslides?

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.

Where do landslides happen most?

The primary regions of landslide occurrence and potential are the coastal and mountainous areas of California, Oregon, and Washington, the States comprising the intermountain west, and the mountainous and hilly regions of the Eastern United States. Alaska and Hawaii also experience all types of landslides.

How does earthquake affect us?

Some of the common impacts of earthquakes include structural damage to buildings, fires, damage to bridges and highways, initiation of slope failures, liquefaction, and tsunami. … Buildings can be designed to withstand most earthquakes, and this practice is increasingly applied in earthquake-prone regions.
