natural environment, even now, in the twenty-first century, a man is able to present dangerous surprises.Not all effects can be prevented in time and protect people from the consequences.However, as you know, it forewarned - is forearmed.Acquainted with the fact that such a landslide, and how you can cope with it.

Feature

Places and houses located on the banks of rivers, lakes, seas, ravines or steep hill, may become victims of this disaster.It manifests itself most imperceptible way, in what lies the danger.Over time, the ground begins to move, dragging all ground construction.Wherein the layer of soil entrained by force of gravity may move slowly or fast, a few meters per year, or per minute.The reason for the phenomenon lies in the destructive effects of water.She tempted slopes or rocks, imbues them with moisture.Thus, we can define what a landslide that still considered the "calm" disaster.This phenomenon is not that other, as an abrupt displacement of masses of loose soil or rock on the inclined plane.

Causes of landslide

Move layer of earth or stone rocks may be an earthquake.Also it can have a devastating impact human activity.For example, blasting.This natural phenomenon may occur if the resistance broken rock or soil, especially if the slope has a waterproof layer consisting of clay.It acts as a lubricant.With strong moistening the soil increases the danger of slipping.Between the clay particles reduces adhesion.We can say that atmospheric water, underground springs and the winds serve as a catalyst for the development of natural hazard.Therefore, sliding soil is most often observed in the spring after the snow melts or after heavy rains.The fact that such a landslide, and how to behave when it occurs, should be aware of people whose activities are connected with the mountains, or the inhabitants of coastal areas.If the soil is moved at a speed of more than a meter a day, you need a pre-designed plan.In the case of the threat of collapse is conducted evacuation.

Consequences

natural phenomenon leads to the fact that a so-called "landslide body."It takes the form of half-rings.In his mid-generated slide.As a result of avalanches and landslides lead to serious consequences.Broken pipes, houses, roads, cause serious damage to agricultural land.The worst of the consequences of these disasters - loss of life.But the first phenomenon is different from the second speed vanishing mass of soil or rock.With the collapse, which occurs most often in the mountains, everything happens much faster.

most dire consequences of landslides

As an example of the destructive power of this natural phenomenon is the case of the Crimea in 2005.This region, especially its southern part is the most prone to slipping soil layers.In 1994, natural disasters have become a real disaster for Kyrgyzstan.Landslides, moving at a speed of several hundred meters per minute, destroyed many houses, there were no casualties.In Russia, the most dangerous regions of the Volga region are considered - Saratov region, Volgograd, the valley of the Kuban and the many areas of Siberia.Krasnodar region and the Black Sea coast - the place of frequent occurrence of landslides.In 2006, after the melting of snow and rain in the mountains of Chechnya, there was a mass gathering.The rocks, the thickness of which is up to two meters, down from the slopes and caused the destruction of about six dozen of houses in several villages.In the current 2014 there was a huge landslide in Afghanistan, which has suffered as a result of more than two thousand people and destroyed hundreds of homes.

Guide to Action

Examine what a landslide, and exploring this natural disaster, scientists and professionals working in special landslide stations.Approximation hazard may signal the following features.Doors and windows in rooms jammed.Because of the slope, from which is about to collapse landslide begins to ooze water.About what is happening you need to notify the Ministry of Emergency Situations.It should act according to the situation.If you received an alert about the danger, you must first disconnect the house, turn off the gas and water network.After that, prepare for evacuation from the premises, caught in the zone of natural disaster.After the landslide is very dangerous to be in the room, which suffered from a natural phenomenon.Doing this is only if the threat has passed.But it is always worth checking the integrity of the pipeline and wiring.Then, be sure to inspect the integrity of the walls and ceilings.During the rescue operation is recommended to give all possible assistance to the specialists, which eliminate the effects of landslides, recovered from the landslide-affected people.
