Earthquake disaster is one of the natural disasters that cause the most serious economic losses and casualties in the world. At present, earthquake prediction is still a worldwide problem. We should strengthen the study of earthquake science knowledge and help us master the correct methods of shock absorption and self-help and mutual rescue.
When an earthquake occurs, the indoor triangular space formed by the collapse of houses is often a relatively safe place for people to live. Especially in architecture, people choose kitchen, bathroom and other places where rooms are not big and easy to collapse, and corners or tables and other places where solid furniture is easy to form a triangular space for shock absorption. In places where there is no table to hide, protect your head with cushions and other things anyway. Never jump off a building and use the elevator blindly.
Natural disasters, including man-made disasters, are man's greatest enemies. There are many natural disasters, such as earthquakes, acid rain, greenhouse effect and typhoons. Man-made disasters include fire, soil erosion and so on. As early as ancient times, people had no awareness of prevention, and they all prayed to God and Buddha for peace. With the development of society, people know how to protect themselves with scientific and practical methods and reduce the threat of disasters to life. Tell everyone how to use scientific methods to prevent earthquakes and reduce disasters, protect themselves and protect their homes.
According to the survey, there are many major earthquakes in China, such as 15 14 Dali earthquake in Yunnan; 1975 Haicheng earthquake in Liaoning province; 1605 Qiongzhou earthquake in Hainan; 1786 Nan Di earthquake in Kangding, Sichuan; 1976 Tangshan earthquake ... so many disasters, so many people were injured, 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, domestic animals such as horses will break free from the reins and run wildly outside; Hibernating snakes will come out of their holes; Bees will fly around; Dogs will bark, and some livestock will run around in circles; Rats move in groups ... these omens can let people know in advance that there will be an earthquake. If these animals are found to have these abnormal phenomena, we must first distinguish between the true and false, and then report to the Seismological Bureau to prevent them from leaving early. An earthquake doesn't mean you will die. In fact, there are many ways to save yourself. For example, you were trapped under the rubble in the earthquake. At this time, you should not act blindly, but be calm. First, take out your hand and move the ruins slowly. First keep breathing smoothly, then try to breathe and call for help. If you are at home during the earthquake, you must immediately enter a hard small room that has not collapsed to avoid injury. Also, stick it on a solid wall or squat at the door, and survive after the house collapses to avoid being hurt. If you are in the wild, you must avoid steep cliffs to prevent yourself from falling down the mountain. There is also the need to prevent landslides, so as not to slide down. If you are at school, you must obey the teacher's instructions, hide under the desk and pay attention to protecting your head. If you go to physical education class, avoid tall buildings and don't get hurt. If you are in the cinema, you should hide under the viewing chair to avoid the shock, avoid the lights hanging on the ceiling and the hanging objects of air conditioners, protect your head with things, and follow the instructions of the commander to evacuate the scene. 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. _ Natural disasters are not as inevitable as earthquakes, and sometimes they can be completely controlled.
There are also many natural disasters, many of which are human's own "masterpieces". So have this knowledge and don't hurt yourself. 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 suggest you do the following:
1. Protect forests, plant trees and protect water and soil.
This factory should not emit too much exhaust gas, but should use inexhaustible solar energy.
In order to protect the ozone layer, cars should not emit exhaust gas.
4, be careful with fire, don't throw cigarette butts.
5. Learn more about earthquake prevention and disaster prevention, and have awareness of prevention.
6. Save water and cherish every drop of water.
Hard work is ruthless, and life is priceless. Students, as minors, we should improve our safety awareness. At ordinary times, we should strengthen the study of safety knowledge, improve the ability of self-help and self-protection, master the ability of witty escape in critical situations, and actively publicize it to parents, friends and neighbors, so that more people can pay attention to safety and cherish their lives. At the same time, I hope all teachers and students can take this earthquake prevention and disaster reduction exercise as an opportunity to further improve the safety work of our school, eliminate all kinds of safety hazards in the bud, and make our school a veritable "safe campus" and "harmonious campus".

After learning earthquake knowledge, I know the types of earthquakes, which are divided into tectonic earthquakes, collapse earthquakes, induced earthquakes and artificial earthquakes. Among them, tectonic earthquakes have the strongest destructive power, accounting for about 90% of the total number of earthquakes in the world, and _ _ earthquakes belong to tectonic earthquakes.
I also know why the earth earthquakes. Earthquake is due to the continuous movement and change of the earth, which gradually accumulates huge energy, causing sudden fracture of rocks or dislocation of primary faults in some fragile areas of the crust. Earthquake is a natural phenomenon, which is as recognizable as typhoon, rainstorm, flood and lightning.
I also learned how to prevent shock! If you are at home and have no time to run after a sudden earthquake, you can hide under or next to solid furniture such as tables and beds, or in corners, kang edges, bathrooms, storage rooms and other places, because small rooms can be relatively supported when houses collapse.
If there is an earthquake in the school, the classroom is a building. Hold your head quickly, close your eyes, hide under or beside the desk, and cover your head with a schoolbag. Don't panic, rush to escape, and don't jump off a building. After the earthquake, the teacher will organize a quick evacuation from the classroom to an open place.
If there is an earthquake in the street, we'd better put a leather bag or something soft on our heads, and we can also protect our heads with our hands when there is nothing to prevent advertising signs, tinplates and neon frames from falling and hurting people.
If there is an earthquake in the theater or gymnasium, we can hide under the row chairs, and the corner is also a suitable shock absorber.
I will definitely read more extracurricular books and learn more knowledge in the future.

In the morning, we are listening to math class attentively. Suddenly, the Chinese teacher walked into the classroom with a serious face and said to the math teacher, "The earthquake drill is about to start. Are the students ready? " The math teacher shook his head and said, "I'm not ready yet." So the math teacher put down the chalk in his hand and said to the students, "Everybody put everything in your schoolbags in your desks, and the earthquake drill will begin soon." Listen up, everyone. The first alarm was to hide under the desk and cover your head with a schoolbag. The second alarm is to evacuate to the playground, and all actions are under command. Do you understand? " "I understand!" The students answered in unison. After that, the classroom was noisy and the ceiling was falling down. Some students are busy packing their schoolbags, while others are whispering. I thought while sorting out my schoolbag: Really, didn't I do it once last year? The headmaster is redundant! But on second thought: the headmaster is also for us. What if the earthquake really comes?
When we are all seated, the math teacher said, "We will have math class later, so just wait for the alarm clock to ring." As soon as the voice fell, the classroom was silent, and you could even hear the sound of a needle falling to the ground. After a while, the shrill alarm finally sounded, and the students quickly and nimbly got under the desks, and I was no exception. I looked around and saw my classmates in front protecting their heads with schoolbags. That action is very standard, no less than professionals! Looking at his deskmate, he smirked and said, "Hey! This' earthquake' is really fun. " I thought to myself: you are such a dead person, you are still laughing when the earthquake really comes, hum! It's too late to cry I looked up and opened XXX on the left, but he couldn't get in. Maybe he has eaten too much recently and got fat.
About a minute later, the second alarm sounded, only to see the math teacher shouting: "Students leave quickly!" " "Hearing this, we were like birds ready to go. We got instructions at once, flew out and followed the teacher downstairs, but when we got downstairs, I didn't know which daredevil said," Run! The Japanese devils have entered the village! " This sentence made us laugh, but we soon calmed down and followed the teacher to a safe place.
When we arrived at the big playground, we all breathed a sigh of relief and put down a big stone in our hearts. Look at the teaching building, the crowds are coming like a flood, which is spectacular! We sat on the ground in anticipation, waiting for the headmaster to speak on the rostrum.
After a while, the headmaster strode onto the platform and said, "Students, this earthquake drill was very successful. Our whole school only took two minutes and fifty seconds! I declare that this earthquake drill has come to a successful conclusion! " Applause suddenly broke out below, magnificent, magnificent and earth-shattering. It was a long time before we reluctantly returned to the classroom.
Through this earthquake drill, I suddenly realized that the headmaster held this activity to let us know that flower of life can only be opened once. If it is lost and withered, it will never be there, so we really should cherish life. At this time, I remembered the May12 earthquake, and scenes appeared in front of me. Pieces of criss-crossing concrete slabs and steel bars seized the fresh life, and my resentment against the principal was immediately thrown out of the clouds. I thought: ah! Let's cherish life. Is life more important than money?

On the afternoon of May 12, an earthquake of magnitude 8 occurred in Wenchuan, Sichuan. Through the uninterrupted TV news, I am saddened to see that there are many schools in the collapsed ruins, and the students who are attending classes are instantly killed by ruthless disasters, and many students are still groaning and calling for help in the ruins of schools ... Seeing this, I shed tears sadly.
I am surprised that the Wenchuan earthquake was not predicted in advance and people were unprepared. Because I know in "100,000 Why" that there will be many omens before an earthquake. For example, there are often small earthquakes before earthquakes, and many animals will show abnormal panic before earthquakes. More importantly, China is relatively advanced in earthquake prediction. Now we have advanced observation instruments and satellite images, but this time there is no prediction. Why? It seems that there is still a big gap between our predictions of natural disasters!
The earthquake is coming, what should we do? Whether to run or hide during an earthquake, most experts in our country believe that it is a better way to avoid nearby during an earthquake and evacuate to a safe place quickly after the earthquake. The shock absorber should be selected in a place that is strong indoors, can cover the body and is easy to form a triangular space. If an earthquake comes, we should hold our heads quickly, close our eyes and hide under the desk under the teacher's command during class. After the earthquake stops, we should evacuate in an organized way. If an earthquake comes, when we are in the playground or outdoors, we can stay where we are, cover our heads with our hands, and pay attention to avoid tall buildings or dangerous things. Evacuation should be organized after the earthquake. Don't go back to the classroom Never jump off a building! Don't stand outside the window! Don't go to the balcony Classes should be held outdoors when necessary. If you are unfortunately buried under waste, you must be strong and don't shout in fear. Save your strength and use all resources to save yourself. In the face of disasters, we should keep our desire to survive and not be intimidated by disasters.
Earthquake is a natural disaster. Although it can't be stopped and changed artificially, we can save ourselves by understanding, recognizing and mastering some relevant knowledge and common sense, so as to minimize the disasters caused by the earthquake and protect our own safety.

Earthquake disaster is one of the natural disasters that cause the most serious economic losses and casualties in the world. At present, earthquake prediction is still a difficult problem, so we should strengthen the study of earthquake science knowledge to help us master the correct methods of shock absorption and self-help and mutual rescue.
In order to improve self-rescue ability, organized by school leaders, our school organized all teachers and students to conduct an earthquake escape drill on June 12.
At nine o'clock in the morning, the exercise officially began. When the alarm sounded suddenly, under the guidance of the teacher, the students quickly picked up books or schoolbags to protect their heads and squatted under the table. Students near the door, after opening the classroom door, try to curl up, lower the center of gravity, and grasp solid objects such as table legs. The whole action should be done in one step. After the noise, the teachers and students fled the teaching building in an orderly manner according to the pre-planned order. The exercise was a great success, and everyone performed well.
I really benefited a lot from my personal experience in this earthquake exercise. Facing the earthquake disaster, we can't stop it from coming, but we can protect our own safety by learning and understanding the escape skills. Through this exercise, students' self-protection awareness and self-protection ability can be enhanced. When disaster comes, we can keep it to a minimum, instead of knowing nothing. This exercise is really necessary.
