On May 28th, 2008, an earthquake measuring 8.0 on the Richter scale occurred in Wenchuan County, Sichuan Province, China. In just a few seconds, at this moment, the surrounding area of Wenchuan became a ruin. How many people lost their loved ones, how many people died, and how many people became disabled ... This earthquake shocked the people of the whole country and left an indelible shadow in the hearts of Sichuan people.
According to the statistics of relevant personnel, when the earthquake occurred, the real loss caused by the disaster itself was not great, so what caused so many deaths? It turns out that the real "killer" is panic. Panic makes many people just follow the actions of others and can't think calmly. Driven by the instinct of escape, people either jumped off the building in a hurry, or trampled on each other to die, or failed to escape to a relatively safe place in time before the building collapsed. ...
So, what should we do when the earthquake disaster comes?
First of all, the most important thing is to keep calm, keep a clear head, identify the vibration situation in time, and never panic, lose your mind, and don't panic. This is particularly important. Secondly, according to the building layout and indoor conditions, size up the situation, find a safe space and passage to escape, and quickly evacuate to a safe place after the first round of earthquake waves to reduce casualties. It can be sheltered under solid furniture, and can also be moved to corners, kitchens, bathrooms and other places where there are many beams or columns and small bays. Because these places have strong bonding ability, especially after pipeline treatment, the supporting force is good and the seismic coefficient is large. Third, don't hide near places with insufficient bearing capacity and easy to collapse, such as doors, windows and stairs. Don't jump off a building and don't panic. Don't stay near buildings and telephone poles to prevent falling objects from hurting people. Fourth, keep the stairs, corridors and other passages unblocked at ordinary times, and don't pile up items in the corridors, which will affect escape in an emergency.
Let's take action, seriously study the knowledge of earthquake prevention and disaster reduction, arm ourselves with scientific knowledge of earthquake prevention and disaster reduction, and defend our lives!

At noon today, we organized a science and education film on earthquake prevention and disaster reduction, from which I learned a lot.
When an earthquake comes, you shouldn't panic. You should find some reasonable places to hide. What are the reasonable places? Let me tell you something I saw on TV.
At school, when the earthquake comes, we should hide under the desk in time and protect our heads, because the heads are the most important part of our bodies. At home, when an earthquake is coming, you should hide under a solid table or under a bed in time, but remind everyone not to hide on the balcony at home. Because the balcony is not closely connected with the main body, it is easy to cause casualties. So, what can we do outside? Don't worry, if you are outdoors, you should squat on the lawn without buildings nearby and hold your head. It's safer. If you are in the cinema, don't panic. You can hide under the chair. I know how to protect myself when the earthquake comes, but when buying a house, what kind of house should I choose to safely and effectively prevent the impact of the earthquake? Don't worry, let me tell you:
When buying a house, you should choose the following houses: bamboo house, low-rise house and so on. Know what kind of house to choose. Someone will definitely ask, how did the government predict the earthquake? Don't worry, don't worry, let me tell you.
The government made effective use of earthquake waves. Jump a few times in front of the seismic wave instrument, and there will be seismic waves on this instrument. Don't worry, it's not a real earthquake. In fact, China's knowledge torch was lit in ancient times. The ancient technology was not very developed, but this seismograph can predict earthquakes millions of kilometers away, and it is very accurate. Will there be an earthquake in the water?
But uninhabited underwater generally does not affect human life and death. But if there is an earthquake along the coast, it will trigger a tsunami and threaten mankind.
Students, we must know more about natural phenomena and lay a solid foundation for effectively protecting our bodies when natural disasters come.

I picked up this heavy pen in my hand, but I didn't know how to write it. What emerges in my mind is still shocking pictures, and what I hear in my ear is still screaming at the top of my lungs, crying with heart-wrenching pain, and moaning tragically. ...
"Disaster", what a terrible word! Life, in the face of this sudden catastrophe, is so small and fragile. Even if we try our best to fight, how many young lives can we call back and make the fallen lives stand up again? In the face of natural disasters, earthquakes, tsunamis, floods and fires, how small human beings are ... all kinds of disasters occur frequently. At the moment of disaster, suddenly, dark clouds were gathering, and the next moment, everything was fragile. In just a few minutes, the once prosperous city suddenly turned into ruins, the once beautiful home instantly turned into the grave of death, and the once laughter, peace and tranquility disappeared instantly. Panic is everywhere, and the number of dead and missing people is repeatedly reported in the news ... since you can't control the natural disaster, start from yourself!
We should focus on the basic elements of disaster prevention. When disaster is imminent, we must not panic, let alone wait for death. That's the stupidest behavior. We should make various responses to various disasters. For example, in the event of an earthquake, if possible, put soft items on your head, hide them under tables and other items, and run to an open place immediately when you have time; In case of sudden tsunami and flood, try to run as high as possible or hold a solid table tightly; In case of fire, cover your nose and mouth with a wet towel and run to an open place. Never take measures to jump off a building. We must keep these measures in mind and stop being at a loss for the coming disaster. creek
When we face the test of disaster, should we reflect? The occurrence of disasters has a lot to do with our environment. We can't stop destroying the environment, otherwise, nature will repay us bit by bit. What a terrible thing! However, what is even more frightening is that we are reckless and destroy the environment-human beings! We always ignore other details for our own benefit, and always make actions to break the external environment inadvertently. It is precisely because of these casual actions on weekdays that the current results have been led. Don't you think it's ridiculous that we destroy the environment to gain our own interests, and the environment slowly returns to us, and then we exchange our former interests for life?
What a wonderful world it used to be. It's a pity that those beautiful things only belong to the past ... Now, the environment is getting worse and worse because of human behavior, so nature begins to retaliate against human beings, which is the price after we destroy the environment! Is it worth it? Answer: not worth it!
Oh, as long as each of us changes a little, I believe that the world will definitely return to its previous appearance!
Let's remember this slogan: care for life, prevent and reduce disasters!

With a pen in my hand, I feel so heavy that I don't know where to start. Horrible images are constantly emerging in my mind, and the cry for help is ringing in my ears from time to time; That cry of pain; Hysterical phone calls for relatives. ...
This is a disaster, and these two words alone can make everyone fear, not to mention that disaster has really befallen us. Disasters include many kinds: natural disasters such as earthquakes, fires, typhoons and mudslides. As early as ancient times, people had no awareness of prevention and did not know how to prevent it. They all prayed to God for peace. With the development of social science and technology, people know how to protect themselves with scientific principles, predict disasters in advance and reduce life risks. This article will tell you how to use scientific methods to prevent earthquakes and reduce disasters, protect yourself and protect your home.
According to the survey, there have been many major earthquakes in many places in China, such as: 1975 Haicheng earthquake in Liaoning, 1976 Tangshan earthquake, Wenchuan earthquake in 2008 ... There were so many disasters and so many casualties, especially the Tangshan earthquake, which killed more than 200,000 people.
In fact, some disasters can be prevented. Before the earthquake, there will be some signs. For example, a hibernating snake will come out of the hole; Bees will fly around; Dogs will bark, and some livestock will run around in circles; Ants move in groups ... these omens can let people know in advance that there will be an earthquake, so as to avoid it and evacuate early. An earthquake doesn't mean you will die. In fact, there are many ways to save yourself. For example, when an earthquake strikes, you are crushed under the rubble. At this time, you should not act blindly, but be calm. Take out your hand first, move the ruins slowly, keep breathing smoothly, find some hard wooden sticks or steel bars to support the surrounding ruins to prevent aftershocks, and then look for food or water nearby. If you are at home during the earthquake, you must immediately enter a small room that is strong and has not collapsed to avoid injury. There was an earthquake in the shopping center. Avoid glass cabinets, commodities, billboards, lights and other items. If you are on the bus, you should hide under the chair or squat down, keep your center of gravity stable and grab the handrail.
Other natural disasters are not as inevitable as earthquakes, and sometimes they can be completely controlled. Not only natural disasters, but also man-made disasters. Such as fire, debris flow, soil erosion, etc. It is human beings who cut down trees themselves and cause unnecessary losses. Therefore, I call on you to do the following:
1. Protect forests, plant trees and protect water and soil.
This factory should not emit too much waste gas.
3. In order to protect the ozone layer, drive the car correctly.
4. Learn more about earthquake prevention and disaster prevention, and have awareness of prevention.
5. Save water and cherish every drop of water.
6. Save electricity.
For our tomorrow, let's take action to prevent disasters and make tomorrow's earth more brilliant!

Today, we all conducted an emergency drill for earthquake prevention and disaster reduction in Dafang Primary School!
The exercise has begun. At this time, there was a sound of "Oh-Woo-"on the radio. For the students in our class, it is like the end of the world. King Dog covered his head and nose with a towel in his right hand and hid under the table, making a banging noise. The classroom is full of students' panic! How great I am! After a while, the "air raid alarm" sounded. One by one, we stood up and screamed, and we hurried into the corridor like we were in a hurry. One by one, orderly, lined up into the stairwell, which was blocked! I look forward to it, I look forward to it, wow! This is a spectacular scene. The front is dark, like a big black cloth. The students are very scared. They covered their noses with their hands and waited for three or four seconds to "open to traffic". Under the guidance of the teacher, we finally opened to traffic! We all hurried downstairs and didn't dare to neglect at all!
Downstairs, we found that the playground was covered with orange smoke, just like an orange veil. The playground is crowded with people, all squatting with towels over their noses after working overtime. We walked through the crowd and came to our area. After a big circle, Liu Liangrong, the squad leader, began to count carefully, and we all squatted and waited for the "lifting alarm" to sound. Students, began to talk in succession, the playground was crowded with people, and the comments spread all over the playground! The teacher doesn't know how to say "get down!" I remembered that the stairwell was really dangerous just now. Fortunately, we have the guidance of the teacher, otherwise we would have been injured in the real earthquake! Alas, I still need to learn more about earthquake prevention in the future! Otherwise, in the real disaster, we humans are so small!
I was just thinking about it when I suddenly thought of "disarming the alarm". We lined up in two neat teams, braved the drizzle and prepared to go back to the classroom. This drill is really meaningful! I think we should learn more knowledge about earthquake prevention in the future, otherwise we can't protect ourselves in the disaster.
