What should we do in the event of a sudden geological disaster landslide?

Sudden disasters sometimes occur in an instant, so we must master the methods of facing some sudden geological disasters. Landslide is a relatively common geological disaster, which mainly refers to the phenomenon that the soil or rock mass on the slope is affected by rivers, groundwater, rain or **, and slides along the slope along the relatively weak part of the slope or as a whole or scattered under the action of gravity. In addition, in some areas, there will be sudden landslides in the mountains after encountering the influence of heavy rain and other weather.

Generally, the local geological department will regularly check the safety factor in places prone to landslides, but there are also some places where landslide disasters will occur suddenly, so we generally do not travel to the mountains after the rain, especially after the rainstorm, and try not to get too close to the mountains. After the occurrence of **, you should also find a flat place to stay, and you can't stand at the foot of the mountain. Moreover, landslides tend to bury the objects below, and landslides are often accompanied by rocks rolling down, which is extremely dangerous.

In the face of a sudden landslide, you should not panic at first, and if you find yourself standing on the landslide, you should move as quickly as possible to a safe place around you.

In general, landslides have enough time to escape except for high-speed landslides, and as long as you look at the surrounding area, you should be able to avoid danger by acting quickly. However, it is best to run to both sides in the direction of escape, because it is dangerous to face a downward landslide, whether it is up or down. If you encounter a sudden high-speed landslide and you don't have time to run around, first calm down, and then find surrounding trees and other objects to hug, and try not to go down with the landslide.

If there are no large trees or other objects that can be used to hold around, try to find some sturdy objects, use them as cover (not on the uphill or downhill slopes of the landslide), and take care to protect your head.

If we find a place where there may be a landslide, we must tell the neighboring residents, the relevant units of the village and township in time, and be careful not to stand in the dangerous area to ensure our own safety. If a sudden landslide ends, the first thing to do is to wait in a safe place, and you can't move around rashly, because the landslide is likely to happen not just once, but continuously.

First of all, it is necessary to be calm, not to panic, and to quickly evacuate to a safe place from the periphery of the boundary on both sides of the landslide; In the event of a landslide, run in the direction perpendicular to the rockfall.

First of all, we try to avoid staying in the area where there is a risk of landslides, if there is a landslide, immediately evacuate the danger area, colleagues should call for help**, try to gather in the town, so that at least there is a response.

Personally, I think that first of all, we should keep our composure, and then we should observe our surroundings in time so that we can find a suitable place to hide in time. Secondly, after finding a place to hide, if there is a signal on the mobile phone, call for help** in time and wait for rescue. Also, wait for the landslide to stop before moving to a safer place, and remember not to run back home because of your own finances.

Debris flows are often characterized by sudden, ferocious and rapid onset. It also has the dual effects of collapse, landslide and flood damage, and its harm degree is more extensive and serious than that of a single collapse, landslide and flood.

One of the most common hazards of mudslides is to rush into villages and towns, destroying houses, factories, enterprises and institutions, and other places and facilities. Drowning people and livestock, destroying land, and even causing disasters such as the destruction of villages and the death of people. Debris flows can directly bury stations, railways, highways, destroy roadbeds, bridges and culverts and other facilities, resulting in traffic interruptions, and can also cause running trains and cars to be subverted, resulting in major personal accidents.

Sometimes, mudslides flow into the river, causing large changes in the river, indirectly destroying roads, railways and other structures, and even forcing roads to be rerouted, causing huge economic losses. In addition, debris flows will wash away hydropower stations, diversion channels and ditch buildings, bury the tail canals of hydropower stations, silt reservoirs, abrasive dam surfaces, destroy mines and their facilities, bury mine tunnels, injure mine personnel, cause shutdown and even scrap mines.

Landslides not only cause loss of people and property within a certain range, but also pose a serious threat to nearby road traffic. Landslides often cause huge losses to industrial and agricultural production, as well as people's lives and property, and sometimes even devastating disasters. The main hazards of landslides to rural areas are the destruction of farmland, houses, harm to people and livestock, destruction of forests, roads, agricultural machinery and facilities, water conservancy and hydropower facilities, etc., and sometimes even cause devastating disasters to rural areas.

Landslides located in towns often bury houses, people and animals, destroy fields, destroy factories, schools, government agencies, etc., and destroy various facilities, causing power outages, water outages, work stoppages, and sometimes even entire towns. Landslides that occur in industrial and mining areas can destroy mine facilities, workers, destroy plants, and stop production of mines, often causing heavy losses.

The following methods can be taken to mitigate landslides, mudslide disasters and reduce losses caused by geological disasters:

1.Geological hazard investigation: Conduct detailed investigation and assessment of potential geological hazard areas to reveal potential geological hazard hazards and provide scientific basis for formulating prevention and response measures.

2.Construction reinforcement works: For example, construction of slope protection, retaining walls and other reinforcement works in potential landslide and collapse areas to enhance the stability and impact resistance of the geological body.

3.River dredging: clean up and strengthen the management of river failure, enhance the stability of water flow and the ability to discharge mud and rocks, and reduce disasters such as floods and debris flows caused by river siltation.

4.Vegetation restoration: Planting trees and other vegetation in mountainous areas or near rivers to enhance soil structure and water retention capacity, and reduce the occurrence of geological disasters such as landslides and mudslides.

5.Early warning and avoidance: Provide early warning of geological disasters to residents in the area, and organize evacuation and evacuation in a timely manner to reduce casualties and property losses as much as possible.

6.Capital investment: The state, local governments and all sectors of society can support relevant scientific research and technology development through capital investment, so as to provide material support for reducing the losses caused by geological disasters and improving response capabilities.

In the on-site rescue, I have to deal with it in accordance with the principle of "saving people first, and then getting out of danger", and the specific rescue operations include the following aspects.

First, arrange for the treatment of the wounded, and let the staff of the village infirmary treat the wounds of the less seriously injured people; Contact the vehicle to arrange for the village cadres to accompany the seriously injured patients and Ling Zao to the hospital in the town, and ask the higher authorities to send a professional medical team to support. At the same time, I will actively reassure the injured people and their families.

Second, help the masses get out of danger. On the one hand, organize villagers to carry out self-rescue work to minimize the loss of life and property. On the other hand, contact the staff of the armed police and the traffic department, and ask them for support to help our village restore traffic as soon as possible and open the passage of life.

In addition, through village broadcasting, cadre mobilization and other means, actively transfer and resettle the masses, take the masses to the high ground or far away from the mountain, and inform everyone of the recent weather and rescue Wang Dou.

Third, in order to prevent more personal and property losses caused by secondary disasters caused by debris flows, I will arrange for villagers to pay close attention to the scene of debris flows and the surrounding mountains along the route, strengthen hidden danger investigation and monitoring and early warning, and inform the incoming and outgoing rescue vehicles to maintain distance and control speed.

When encountering landslides or landslides, the high disturbance mu should run desperately in the direction of rolling stones or slippery Qisen slopes. （）

a.That's right. b.Mistake.

Correct Answer: B

When encountering a landslide, the correct approach is: quickly look around and evacuate to a safer place; Generally, except for high-speed landslides, as long as you act quickly, it is possible to escape from the danger area; When escaping, it is best to run to the sides.

Landslide refers to the effect and phenomenon that a certain part of the rock and soil on the slope of the mountain slope is sheared and displaced along a certain weak structural plane under the action of gravity (including the gravity of the rock and soil itself and the dynamic and static pressure of groundwater). It is one of the common geological hazards.

There are certain signs before a landslide, such as before a large slide. At the foot of the slope at the front edge of the landslide, there is a revival of the spring water that has been blocked for many years, or there are similar anomalies such as the sudden drying up of the spring water and the sudden change in the water level of the well. In the landslide body.

Transverse and longitudinal radial cracks appear in the front, which reflects that the landslide body has been pushed forward and obstructed, and has entered a state of imminent slip.

At the foot of the slope at the front edge of the landslide, the soil body is uplifted, which is the obvious forward pushing phenomenon of the landslide. There are rocks that crack or are sheared and squeezed. This phenomenon reflects deep deformation and rupture.

Animals are very sensitive to this and have abnormal reactions. When it is found that there are any of the above differences, it should be evacuated in time.

The spatial distribution of landslides is mainly related to geological factors and climate.

1. The bank slope area of rivers, rivers, lakes (reservoirs), seas and ditches, canyon areas with large terrain elevation differences, slope sections of mountainous areas, railways, highways and engineering buildings, etc.

2. In the geological structure zone, such as fault zone, ** zone, etc. Generally, areas with a intensity greater than 7 degrees and slopes with a slope greater than 25 degrees are very prone to landslides.

3. Rock and soil distribution areas that are easy to slip (slope). For example, the existence of loose overburden, loess, mudstone, shale, coal measure bridge chain strata, tuff, schist, slate, phyllite and other rocks and soils provides a good material basis for the formation of landslides.

4. Areas prone to heavy rainfall or abnormally heavy rainfall. In these areas, the abnormal rainfall provided favorable triggers for landslides.
