There are likely to be aftershocks after the earthquake, and the location of the aftershocks may not be very close to the source. So learning to save yourself is one of the most important measures after the earthquake.

When an earthquake happens, it is very important to keep a clear head and a calm attitude. Only when you are calm, it is possible to judge the magnitude and distance of an earthquake with the earthquake knowledge you usually learn. Recent earthquakes often start with ups and downs and then swing from side to side. The teleseism is not so bumpy, but it is mainly shaking from side to side, with clear voice and small vibration. Generally, small earthquakes and distant earthquakes do not have to flee.

School shock absorption

When you are in the playground or outdoors, you can squat down in place, protect your head with your hands, and pay attention to avoiding tall buildings or dangerous objects.

Don't go back to the classroom

Evacuation should be organized after the earthquake.

Never jump off a building! Don't stand outside the window! Don't go to the balcony

Classes should be held outdoors when necessary.

Family shock absorption

The earthquake warning time is short, and the indoor shock absorption is more real, and the triangular space formed after the collapse of indoor houses is often a relatively safe living place for people, which can be called shock absorption space. This mainly refers to the space formed by large collapsed bodies and supports.

Indoor triangular space is easy to form:

Under the edge of the kang, close to solid furniture;

Root and corner of interior wall;

Kitchen, bathroom, storage room and other small places.

Shock absorption in public places

Listen to the instructions of the field staff, don't panic, don't rush to the exit, avoid crowding, avoid crowds, and avoid being pushed to the wall or fence.

In theatres, gymnasiums, etc:

Pay attention to avoid hanging objects such as chandeliers and electric fans;

Protect your head with a schoolbag, etc.

After the earthquake, listen to the command of the staff and evacuate in an organized manner.

In shopping malls, bookstores, exhibitions, subways, etc.:

Choose solid counters and commodities (such as low furniture, etc.). ) or pillars, and squat down in the inner corner, and protect your head with your hands or other things; Avoid glass doors and windows, glass windows or counters; Avoid tall and unstable shelves or shelves with heavy objects and fragile items; Avoid tall or hanging objects, such as billboards and chandeliers.

In a moving electric (automobile) vehicle:

Grasp the handrail to avoid falling or bumping; Lower your center of gravity and hide near your seat.

Don't get off until the earthquake has passed.

Outdoor shock absorption

Field selection of outdoor shock absorber;

Squat or get down to avoid falling;

Don't run around and avoid crowded places;

Don't go back indoors casually.

Avoid tall buildings or structures:

Buildings, especially those with glass curtain walls;

Crossing bridges and overpasses;

Under tall chimneys and water towers.

Avoid dangerous objects, towering or hanging objects:

Transformer, telephone pole, street lamp, etc. ;

Billboards, cranes, etc.

Avoid other dangerous places:

Narrow streets;

Dangerous old houses, dangerous walls;

Under the parapet, high gate face and awning;

Bricks, wood and other things piled up.

Workshop worker shock absorption

Workshop workers can hide under cars, machine tools and tall equipment, and don't panic and run around. Workers in special posts should first close the valves of flammable, explosive and toxic gases, reduce the temperature and pressure of high-temperature and high-pressure pipelines in time, and close the operation equipment. Most people can leave the work site, and a few people can stay at the site to monitor the danger at any time under the premise of safety protection, deal with possible accidents in time and prevent secondary disasters.

Emergency shock absorption of running vehicles in earthquake.

(1) The driver should slow down as soon as possible and brake gradually;

(2) Passengers (especially on the train) should firmly grasp the handle, post or seat with their hands, and pay attention to prevent luggage from falling from the luggage rack and hurting people. People facing the driving direction should put their arms on the seat cushion in front, protect their faces, lean toward the passage, and protect their heads with their hands; People with their backs to the direction of driving should protect the back of their heads with their hands, raise their knees to protect their abdomen, tighten their bodies and take a defensive posture.

Emergency shock absorption of people in buildings during earthquakes.

Once an earthquake happens, keep a clear head, judge the vibration in time, and never jump off a building in a panic. Secondly, you can hide under solid furniture, or in a corner, or you can move to a kitchen, toilet and small room with many load-bearing walls for temporary shelter. Because these places have strong binding force, especially the pipeline has good supporting force and large seismic coefficient after treatment. In a word, according to the building layout and indoor conditions, we can evaluate the situation and find safe spaces and passages to avoid and reduce casualties.

Emergency shock absorption in the store during earthquake

The department store kept calm when it was hit by an earthquake. Due to the panic of people and the falling of goods, the refuge passage may be blocked. At this time, you should hide near big pillars and big commodities (avoid commodity display cabinets), or hide in an unobstructed passage, and then bend down and wait for the earthquake to subside. In the upstairs position, in principle, it is best to transfer to the ground floor. However, stairs are often the weak parts of buildings in earthquake resistance. Therefore, we must seize the opportunity to escape. Attendants should organize the masses to avoid nearby and evacuate safely after the earthquake.

Three strategies for shock absorption of high-rise buildings

Strategy 1: Stay calm during the earthquake and go outdoors after the earthquake. This is an international standard for earthquake prevention. Many earthquake examples at home and abroad show that people are most likely to be killed or injured when they enter or leave buildings in a short time. Therefore, experts remind that indoor shock absorption conditions are good, and indoor shock absorption must be selected first. If the building has poor earthquake resistance, try to run out of the room.

According to the relevant national standards, residential buildings in Beijing should have the ability to resist the damage of the 8-degree earthquake. Don't panic when an earthquake happens, keep your vision wide and moving so that the camera can move. Especially don't stay in bed; Don't run to the balcony; Don't run to the corridor where there are many people; Don't jump off a building; Don't use the elevator. If there is an earthquake, you should leave the elevator as soon as possible. If the door won't open, hold your head down. In addition, it is necessary to immediately put out the fire and cut off the power supply to prevent burns, electric shocks and fires.

Strategy 2: The position of shock absorber is very important. If you live in a building shock absorber, you can judge the situation according to the building layout and indoor conditions and find a safe space to escape. It is best to find a place where a triangular space can be formed. It's safer to squat next to the heater, which is very important. The reticular structure and elasticity of metal pipes are not easy to be torn, and it is not easy to be thrown out even if there is a big earthquake. The heating pipe is well ventilated, which is not easy to cause suffocation; The water stored in the pipeline can also prolong the survival period. More importantly, trapped people can send information to the outside world by tapping the heating pipe, and the location of the heating near the external wall is conducive to getting help as soon as possible.

Hiding in a small room like kitchen and bathroom, pay special attention to stay away from stoves, gas pipes and fragile dishes. If the kitchen and bathroom are located in the corner of the building and the partition wall is thin-walled, don't choose it as the best location for shock absorption. In addition, don't get into cabinets or boxes, because once people get into them, they will immediately lose their mobility, their vision will be blocked, and their limbs will be tied, which not only misses the opportunity to escape, but also is not conducive to being rescued; Poor lying posture increases the plane area of human body, and the probability of being hit is five times greater than that of standing posture, making it difficult to maneuver.

Strategy 3: near water is not close to fire, but outside rather than inside. This is an important principle to ensure timely assistance from others in urban earthquakes. Stay away from gas stoves, gas pipelines and household appliances; Don't choose the internal position of the building, try to be close to the external wall, but don't hide under the window; Try to get close to the water source. Once trapped, try to contact the outside world. In addition to using a mobile phone, you can also use water pipes and radiators or turn on a flashlight.

Tips for family shock absorption

1. Take time to avoid danger urgently. If you feel that the shaking is very light, it means that the source is far away. Just hide under solid furniture. The shaking process from the beginning to the end of a major earthquake takes only ten seconds to dozens of seconds, so it is most important to seize the time to prevent earthquakes, so don't delay the time.

2. Choose a suitable shockproof space. The safer indoor earthquake-proof space is: the root and corner of the load-bearing wall; There are water pipes and warm air pipes. The most unfavorable places for shock absorption in the house are: unsupported beds; Under the ceiling and chandelier; On the floor without support around; Next to the glass (including the mirror) and the big window.

3. Do a good job of self-protection. First of all, you should be calm. After choosing the shelter, you should squat or sit down, face down and rest with your forehead on your arm. Or grab a solid object around you, such as a table leg, to avoid falling down during an earthquake or being injured due to out-of-control displacement of the body; Protect your head and neck, bow your head, and protect your head or back neck with your hands; Protect your eyes, lower your head and close your eyes to prevent foreign body injury; Protect your mouth and nose. If possible, cover your nose and mouth with a wet towel to prevent dust and toxic gases.
