8. Knowledge of natural disasters

Overview of natural disasters (natural disaster/natural hazard) "Natural disasters" are abnormal phenomena that occur in nature on which humans depend. Natural disasters often cause harm to human society. It's shocking.

Among them, there are sudden disasters such as earthquakes, volcanic eruptions, mudslides, tsunamis, typhoons, and floods; there are also land subsidence, land desertification, drought, coastline changes, etc. that will gradually appear over a longer period of time. Gradual disasters; there are also environmental disasters caused by human activities such as changes in the ozone layer, water pollution, soil erosion, and acid rain. There are complex interconnections between these natural disasters and environmental damage.

It is a common theme of the international community that humans should understand the occurrence and development of these disasters from a scientific sense and minimize the harm they cause. Natural variations on the earth, including those induced by human activities, occur all the time and everywhere. When this variation brings harm to human society, it constitutes a natural disaster.

Because it brings varying degrees of damage to human production and life, including the relationship between humans and nature through labor as the medium, and the related relationships between humans. Disasters have negative or destructive effects.

Therefore, natural disasters are a manifestation of the contradiction between man and nature. They have dual attributes of nature and society. They are one of the most severe challenges that mankind has faced in the past, present and future. Major sudden natural disasters around the world include: droughts, floods, typhoons, storm surges, freezing damage, hailstorms, tsunamis, earthquakes, volcanoes, landslides, mudslides, forest fires, agricultural and forestry pests and diseases, etc.

There are many types of natural disasters in China. Earthquakes, typhoons, heavy rains, floods, waterlogging, high temperatures, lightning, heavy fog, haze, mudslides, landslides, tsunamis, icy roads, tornadoes, hail, blizzards, avalanches, ground subsidence, sandstorms, etc., occur every year. It occurs nationwide and in local areas, causing widespread damage or devastating blows in local areas.

my country is the country with the most types of natural disasters in the world, among which there are seven categories of natural disasters that have the greatest impact on our country.

1. Meteorological disasters There are more than 20 kinds of meteorological disasters, mainly including the following types: (1) Heavy rain: flash floods, river flooding, urban water accumulation; (2) Rainfall: waterlogging, waterlogging; (3) Drought: agriculture, forestry , Drought in grasslands, water shortage in industry, cities, and rural areas; (4) Hot and dry winds: drought winds, foehn winds; (5) High temperatures and heat waves: extreme heat, human diseases, burns, and ripening of crops; (6) Tropical cyclones: Strong winds, heavy rains, and floods; (7) Chilling damage: Damage to crops, livestock, and fruit trees due to strong cooling and low temperatures; (8) Freezing damage: Frost damage to crops, livestock, and freezing of water pipes and oil pipes; (9) Freezing rain: Electric wires, Branches and roads freeze; (10) Ice: rivers, lakes, and seas freeze, and roads freeze after rain and snow; (11) Snow damage: blizzards, snow; (12) Hail damage: destroy crops, damage houses; (13) Wind damage: falling trees, houses, overturning cars and boats; (14) Tornado: local destructive disaster; (15) Lightning: casualties caused by lightning strikes; (16) Continuous rain (unpleasant rain): detrimental to crop growth and development, food mildew, etc.; (17) Dense fog: human diseases, traffic obstruction; (18) Low-altitude wind shear: (aircraft) aviation crash; (19) Acid rain: damage to crops, etc.

2. Marine disasters Marine disasters mainly include the following types: (1) Storm surge: including typhoon storm surge and temperate storm surge; (2) Tsunami: remote tsunami and local tsunami; (3) Waves: including three types: wind waves, swells and nearshore waves, which are divided into typhoon waves and cyclone waves in terms of their causes; (4) Sea water; (5) Red tide; (6) Coastal disasters: such as coastal erosion, landslides, Land salinization, seawater pollution, etc.; (7) The harm of El Ni?o. 3. Flood disasters (1) Heavy rain disasters; (2) Flash floods; (3) Snowmelt floods; (4) Ice floods; (5) Dam burst floods; (6) Debris flow and cement flow floods.

4. Earthquake disasters (1) Tectonic earthquakes; (2) Subsidence earthquakes; (3) Mine earthquakes; (4) Reservoir earthquakes, etc.; 5. Crop biological disasters (1) Crop diseases: mainly rice There are more than 240 kinds of diseases, including 50 kinds of wheat diseases, more than 40 kinds of corn diseases, more than 40 kinds of cotton diseases and many diseases of soybeans, peanuts, hemp, etc.; (2) Crop pests; there are mainly 252 kinds of rice pests and 100 kinds of water and wheat pests. There are many kinds of pests, including 52 kinds of corn pests, more than 300 kinds of cotton pests, and various pests of other crops; (3) Crop weeds: about 8,000 kinds; (4) Rat pests. 6. Forest biological disasters (1) Forest diseases: 2918 species; (2) Forest insect pests: 5020 species; (3) Forest rodent pests: more than 160 species.

7. Forest fires. The National Science and Technology Commission, the State Planning Commission, and the National Economic and Trade Commission’s Comprehensive Research Group on Natural Disasters divide natural disasters into seven categories: meteorological disasters, marine disasters, flood disasters, geological disasters, earthquake disasters, and crops. Biological hazards and forest biological hazards and forest fires. However, the disasters that are closely related to our daily life mainly include: 1. Geological disasters. Natural variations and man-made effects may lead to changes in the geological environment or geological bodies. When this change reaches a certain level, the resulting disasters such as landslides, debris flows, Consequences such as ground decline, ground subsidence, rock expansion, sand and soil liquefaction, land freezing and thawing, soil salinization, land desertification, earthquakes, volcanoes, and geothermal damage will cause harm to humans and society.

This phenomenon is called a geohazard. Geological hazards also include derived hazards.

(1) Debris flow. Debris flow is a special torrent containing a large amount of sediment and rocks in mountainous valleys, triggered by heavy rain, melting ice and snow and other water sources.

The formation of debris flow: the following three conditions must be met at the same time: steep topography that is convenient for collecting water and materials; rich loose materials; and a large amount of water source in a short period of time. Debris flows can be divided into three categories according to their material composition: debris flows are composed of a large amount of clay soil and sand and stones of different particle sizes; debris flows are mainly composed of clay soil, containing a small amount of clay particles and stones, and have high viscosity and become thick mud-like The one composed of water, sand and stones of different sizes is called water-rock flow.

The hazards of debris flow: hazards to residential areas; hazards to roads and railways; hazards to water conservancy and hydropower projects; hazards to mines; (2) Landslides. The rocks on the landslide are soft to a certain extent under the action of gravity due to various reasons.

9.60 pieces of geographical knowledge about natural disasters

Tips on earthquake prevention and isolation 1. When an earthquake strikes, hide under tables and other solid furniture, and evacuate quickly after the shaking stops. The open area downstairs.

2. During thunderstorms, lightning rods can only protect buildings, but they are powerless against lightning that intrudes along overhead wires and telephones. For home appliance lightning protection, it is best to cut off the power supply to indoor household appliances and unplug the phone.

3. During thunder and lightning weather, it is best for residents not to come into contact with gas pipes, water pipes and various live devices at home. 4. It is not advisable to use the shower head when there is thunder and lightning, because the huge thunder and lightning will attack the bather along the water flow.

Special reminder to you: when purchasing a house, the developer should be required to provide proof of lightning protection installation facilities in commercial housing, so as to avoid hidden dangers for future residence. Top 10 ways to protect yourself from lightning outdoors Lightning usually hits the spire of the tallest object outdoors, so isolated tall trees or buildings are often the most vulnerable to lightning strikes.

During thunder and lightning, people should abide by the following rules when outdoors to ensure safety. 1. Do not stay on high-rise platforms during thunderstorms, and do not enter isolated sheds, guard booths, etc. in open areas outdoors.

2. Stay away from exposed water pipes, gas pipes and other metal objects and electrical equipment in buildings. 3. It is not advisable to shelter from lightning and rain under a big tree. If you have to, keep a distance of 3 meters from the tree trunk, squat down and keep your legs close.

4. If you feel ants walking on your head, neck, or hands during thunder and lightning. If your hair stands up, it means that a lightning strike is about to occur. You should lie down on the ground quickly to reduce the risk of being struck by lightning.

If you encounter a thunderstorm outdoors and it is too late to leave the tall object, you should immediately find some dry insulators and place them on the ground, and sit on them with your feet together. Do not put your feet on the ground other than the insulators, because water can conduct electricity. .

6. When avoiding thunderstorms outdoors, do not support the ground with your hands; at the same time, hug your knees with your hands, keep your chest close to your knees, and lower your head as much as possible, because the head is most vulnerable to lightning strikes than other parts of the body. 7. When you see lightning and hear thunder within a few seconds outdoors, it means you are in a dangerous environment near a thunderstorm. At this time, you should stop walking, put your feet together and squat down immediately. Do not pull together with others. It is best to use Plastic rain gear, raincoat, etc.

During thunderstorms, it is not advisable to drive a motorcycle quickly, ride a bicycle quickly, or run wildly in the rain, because the larger the body step, the greater the voltage, and the easier it is to injure someone.

10. If you see a high-voltage line broken by a lightning strike outdoors, you should be more vigilant at this time, because there is a step voltage near the high-voltage line. People nearby must not run at this time and should keep their feet together. , fled the scene. Flood prevention knowledge 1. Heavy rainstorm: refers to rain with very heavy rainfall.

So how to measure the amount of rainfall? Meteorological staff place a metal cylinder with a diameter of 20 cm - a rain gauge - in the open air at the ground observation site. The amount of rain it receives 24 hours a day is the daily precipitation, which can be measured with a measuring cup. The Central Meteorological Administration stipulates that daily rainfall below 10 mm is called light rain, 10-25 mm is moderate rain, 25-50 mm is heavy rain, and more than 50 mm is called heavy rain.

Heavy rain is dangerous, but it is not terrible.

As long as various precautions are taken, there will be no danger.

2. How to save yourself when a flood occurs: (1) When the flood comes, move and evacuate according to the planned route, pay attention to supporting the elderly and the young, and help each other. If the flood comes too fast and it is no longer possible to move on foot, you should use prepared boats or floating objects such as door panels and wooden beds as water transfer tools.

(2) When the flood comes quickly and the water has entered the house, you must quickly climb onto the roof, wall or nearby tree to take temporary refuge and wait for the rescue personnel to move. Single swimming transfers are not allowed.

(3) Houses with earth walls, dry fortresses or houses with brick walls with mud joints can only be used as temporary shelters, because they are in danger of collapse at any time if soaked in water. (4) If there are no big trees or courtyard walls, and the roof cannot be climbed for a while, you should hold on to the fixed objects at this time and call for help from others to help you escape.

3. What are the common diseases during disasters: The sanitary conditions in disaster areas are poor, especially the sanitation of drinking water is difficult to guarantee. The first thing to prevent is intestinal infectious diseases, such as cholera, typhoid, dysentery, and influenza A Hepatitis etc. In addition, human and animal diseases and natural foci diseases are also very likely to occur during floods, such as rat-borne infectious diseases: leptospirosis, epidemic hemorrhagic fever; parasitic diseases: schistosomiasis; insect-borne infectious diseases: Malaria, Japanese encephalitis, dengue fever, etc.

Skin diseases are also common during disasters: maceration dermatitis (also known as "rotten feet" and "rotten crotch" among the people), insect bite dermatitis, and cercarial dermatitis; accidental injuries are also prone to occur during disasters: drowning , electric shock, heat stroke, trauma, poisonous insect bites, poisonous snake bites, food poisoning, pesticide poisoning, etc. 4. After the flood, how to prevent the spread of diseases: (1) Remove stagnant water and filth, ventilate and dry, spray disinfectants to prevent the breeding of infectious diseases and mosquitoes and flies; (2) Take preventive drugs to avoid the occurrence of infectious diseases.

If an infectious case occurs, isolation and treatment must be carried out; (3) Household utensils must be cleaned and disinfected, and wet and moldy objects must be ventilated and dried. 5. What to do if the road is blocked on the way to or from school: (1) Floods wash out, the road collapses, or the road is cut off in the middle and there is rapids passing through it. At this time, you can only "temporarily take refuge" in a safe place, and you must not pass by force; (2) When mountain roads are blocked due to landslide accumulation, you should take a detour up the mountain. It is safer to pass through the upper part of the landslide surface; (3) When there is a flood.
