What is sel, and how to be saved from this phenomenon?

Do you know what is sel? It is an avalanche of impending soil, which has destructive power. It can arise suddenly, its speed reaches 10 meters per second, and the height of a five-story house. The main danger of mud flows Is a direct impact on the obstacles, for example, buildings, structures, life support systems, including people.

What is sel, and where does it come from?

Selham refers to the flow of a mixture of a large number of pieces of rocks and water that has arisen for a while. The debris can look like clay particles, large blocks and stones. Suddenly appearing mudslides are observed in the hollows and river beds located in the region of the mountains. Often, avalanches from the ground come off in some areas of the Far East and Siberia, the Urals, and the North Caucasus.

The stream of mudflow is born from abundant and prolonged rains, breakthrough of water bodies, volcanic eruptions, earthquakes, intensive melting of glaciers or snow. The nature of the occurrence of the avalanche of the ground is sudden, its speed is large. Most often, the selenium passes not by one wave, but by several in a time interval of 10 minutes to 10 hours.

In the conditions of a disaster, due to the descent of a large amount of soil, there may be a large number of people. After all, what is sel? This is a stream, the roar and roar of which are audible at great distances and can cause panic even among those whom it does not touch.

Consequences of the spontaneous phenomenon

What dangerous consequences can a mud landslide (sel) bring? Due to the descended avalanche of soil, the following factors are always expected:

- a large number of human casualties and injuries;

- destruction of dangerous objects, as well as bridges, roads, structures and buildings;

- grandiose blockages with a mass of stones and dirt;

- destruction of forest tracts;

- significant losses in agriculture.

The threat of mudflow: the actions of the population

When there is information that it is possible for the avalanche to converge in the near future, you should behave as follows:

1. Listen attentively to the information offered by the radio and TV channels concerning the situation. Memorize recommendations about necessary actions.

2. Stay calm, warn neighbors, provide the necessary assistance to children, elderly people and people with disabilities.

3. Explain to those who do not understand what is sel, that to be saved from it is possible only by flight. If there is time to prepare, plan the methods of evacuation of the population.

Thus, it is possible to help people who are nearby.

Individual preparatory actions

If you are threatened by landslides, landslides, sat down, you should do this:

1. Prepare clothes, money, gather valuable and necessary The minimum stock of water and products for a few days, a flashlight, a receiver, a stock of batteries, medicines.

2. Turn off the house gas, electricity, water.

3. Tightly close the windows, ventilation holes, doors.

4. Remove from the premises toxic preparations and flammable substances. In case of this possibility, they should be hidden in a cellar or cellar.

5. Independently go to the hill in a safe place during an emergency evacuation. Its route should be known to you in advance.

Actions in case of sudden convergence of a stream of a ground

When the village starts to descend spontaneously, it is necessary first of all not to give in to panic, to remain calm. As soon as you hear the noise of the approaching stream, you must immediately rise from the low (from the bottom of the hollow) up the avalanche to a height of at least 50 meters. Beginning the process of ascent, it should be remembered that from the lightning-moving mass of the ground large stones threatening life can be thrown out for long distances.

What to do after the descent of the village?

After the movement of the avalanche of mud and stones stopped, try to help the victims and assist the bodies and formations that will deal with the debris and drifts. If in the process of descent of the village you become the victim of the disaster yourself, try to provide yourself with pre-medical help yourself. Later, please contact the doctor.

Sel: examples of the magnitude of the disaster

When describing the convergence of mud flows, we can not fail to mention the recent tragedies. One of them occurred in Afghanistan on October 5, 2011. As a result of the descent from the mountains in the town of Charikar (Parwan Province), 2 people were killed and 12 were injured. The disaster happened when people were already sleeping. More than 1,000 houses in which the city's population lived, were destroyed.

As an example of the action of the elements, one can also cite the case that occurred in Azerbaijan on June 22, 2011. Not one village on that day was flooded with streams of mud in the Ismayilli region. The cause of the disaster were prolonged downpours, the flows of which, mixed with the ground, washed away roads and bridges, de-energized four villages.

Ways to prevent mudflows

In areas where the ground may descend, it is necessary to arrange mud dams and dams, construct bypass canals, strengthen the land on the slopes by planting trees, and reduce the level of mountain lakes. Also it is necessary to conduct constant observations, plan possible evacuation and organize warning systems of the population.
