Introduction: Earthquakes are natural disasters that are unavoidable and the biggest enemy of mankind. The following is an 800-word popular science composition on earthquake prevention and disaster reduction. Welcome to refer to it. Article 1: An 800-word popular science essay on earthquake prevention and disaster reduction for high school students

On the earth we live on, there are various weather conditions and surface movements, and earthquakes are one of them.

We will never forget May 12, 2008. It was a heartbreaking day. The Wenchuan Earthquake took away so many lives, tore apart so many families, and how many people. Children become orphans as a result, and many people will be alone for their entire lives. We cannot turn back time, and we are powerless to change this fact. Only by facing it with strength can we survive this tragic moment and live bravely.

We cannot change disasters, but we can avoid them. Before an earthquake occurs, there will be some warning signs. For example, horses and other livestock will break free from their reins and run wildly; hibernating snakes will rush out of their holes; bees will fly away and flee; dogs will bark, and some domestic animals will break out of the pen and run around; rats will swarm. Move in groups...

Death is not certain when an earthquake occurs. In fact, there are many ways to save yourself. For example: There is an earthquake and you are trapped under the rubble. At this time, don't move blindly. Be calm. Take your hands out first and slowly move the rubble. Keep your breathing smooth first, and then find a way to breathe and call for rescue. you. If you are at home when an earthquake occurs, you must immediately get into a small room that is hard and has not collapsed to avoid being injured. Also, stick to a solid wall or find a soft object to prop your head on, such as a pillow. After the house collapses, try to survive without getting hurt. If you are in the wild, be sure to avoid steep cliffs to prevent falling down the mountain. There is also the need to prevent landslides to avoid sliding down. If you are in school, you must follow the teacher's instructions, hide under the desk, and protect your head. If you are in physical education class, avoid tall buildings to avoid being injured.

Earthquakes are a common natural phenomenon that bring great natural disasters to human beings. Our country is located between the world’s seismic zones and is a country with many earthquakes. Predicting and predicting earthquakes is now an important task. Work.

For a long time, the threat of earthquakes has been as powerful and unavoidable as a thunderstorm on a summer afternoon.

There are also many man-made disasters. Fires, mudslides, soil erosion, etc. are all caused by humans cutting down trees.

Therefore, I suggest that everyone do the following:

1. Protect forests, plant trees, and protect water and soil.

2. Factories should not emit too much waste gas and use inexhaustible solar energy.

3. To protect the ozone layer, cars should not emit exhaust gas.

4. Be careful with fire and don’t throw cigarette butts around.

5. Learn more about earthquake and disaster prevention and be aware of prevention.

6. Save water and cherish every drop of water.

If these points are done first, the occurrence of disasters will be reduced, or many lives will be saved once a disaster occurs.

In short, the earth is our beautiful home, but sometimes accidents occur. Only by actively facing them, developing science and technology, and benefiting mankind can we live happily in this beautiful home. Chapter 2: An 800-word popular science essay on earthquake prevention and disaster reduction for high school students

At 14:28 on May 12, 2008, a major earthquake measuring 8.0 on the Richter scale struck Wenchuan County, Sichuan Province, my country. It took only a few seconds. time, and at this moment, the area around Wenchuan turned into ruins. How many people have lost their loved ones, how many people have passed away, and how many people have become disabled... This earthquake shocked the people across the country and left an indelible shadow in the hearts of the people of Sichuan.

According to statistics from relevant personnel, when an earthquake occurs, the real damage caused by the disaster itself is not great, so what is it that kills so many people? It turns out that the real "killer" is panic. Panic causes many people to just follow others' actions instead of thinking calmly. Driven by the instinct to escape, people either jumped from the building in a hurry, or trampled each other to death, or did not escape to a relatively safe place in time before the building collapsed...

Earthquakes are unpredictable. Human beings can predict the time, magnitude and area of ??earthquakes. If we learn to save ourselves, so many lives will not be lost. We are not reconciled. Although we cannot predict the arrival of earthquakes, we can arm ourselves with earthquake prevention knowledge to accurately prevent and reduce the harm caused to us by earthquakes.

So, what should we do when an earthquake disaster strikes?

Disasters are unpredictable, and we can only rely on ourselves to prevent the damage caused by earthquakes. Instead of It is better to panic or wait for rescue than to try your best to save yourself.

I believe that once an earthquake occurs, the first and most important thing is to stay calm, keep a clear and cool mind, and judge the vibration situation in time. Don’t panic, lose your mind, or panic. This is particularly important.

Secondly, you can assess the situation based on the building layout and indoor conditions, find safe spaces and passages to avoid, and quickly evacuate to a safe place after the first round of earthquake waves to reduce casualties. You can hide under solid furniture, or you can move to a corner with many load-bearing walls and small bays with beams or pillars, the kitchen, or the bathroom to take temporary shelter. Because these places have strong bonding capabilities, especially the pipes that have been treated, they have better support and larger seismic resistance coefficients. Third, do not hide near doors, windows, stairwells, or other places with insufficient load-bearing capacity and prone to collapse. Do not jump off buildings or get stuck in a panic. Do not stay near buildings, electric poles, etc. to prevent injuries caused by falling objects from high altitudes. Fourth, keep stairs, corridors and other passages clear at ordinary times, and do not accumulate items in the corridors, which will affect escape in an emergency. Fifth, after becoming familiar with various self-rescue measures, government units, schools, factories and other densely populated units should organize earthquake self-rescue drills so that the knowledge of written self-rescue measures can be trained and practiced skillfully.

The teachers and students of Sangzao Middle School are examples of using knowledge to protect themselves. An County, where the school is located, is close to Beichuan, where the earthquake was most severe. Due to many daily drills, after the earthquake, all teachers and students in the school, including more than 2,000 students and hundreds of teachers, rushed to the playground from different teaching buildings and different classrooms, and stood in class units. The attack lasted one minute and thirty-six seconds, and no teachers or students in the school were injured or injured, creating a miracle.

Let the whole people take action, seriously study the knowledge of earthquake prevention and disaster reduction, arm yourself with scientific knowledge of earthquake prevention and disaster reduction, and defend your own life! Part 3: 800-word essay on earthquake prevention and disaster reduction for high school students

May 12, 2008, 14:28:04, a moment embodying sadness and carrying grief, a moment that Chinese people will never forget!

I still remember that Sichuan was full of wind that day. The weather was beautiful, the sun was shining brightly, the birds were singing and the flowers were fragrant, and life was full of vitality. However, at that moment, a magnitude 8 earthquake suddenly hit. The earth trembled, mountains and rivers were dislocated, devastation was everywhere, life and death were separated, and in the southwest, state-owned enterprises were in ruins! This was the destruction since the founding of New China. The earthquake with the strongest impact and the largest impact. The earthquake severely damaged about 500,000 square kilometers of China!

As of 10:00 on April 25, 2009, 69,227 people were killed, 374,643 were injured, and 17,923 were missing. Among them, 68,712 compatriots in Sichuan Province were killed, and 17,921 were missing. Compatriots are missing, and 5,355 students in Japan were killed or missing. Direct economic losses amounted to approximately 845.1 billion yuan. This is the earthquake with the greatest impact since the founding of the People's Republic of China.

It can be seen from this that the harm caused by earthquakes to us is huge, and earthquakes are natural disasters that are unavoidable and are the biggest enemy of our mankind. Although we cannot avoid it, with the development of society, we should know how to use scientific principles and methods to protect ourselves, reduce disasters, and avoid threats to our lives. Let’s learn together how to use scientific methods to prevent earthquakes and reduce disasters, protect ourselves, and protect our homes.

Before an earthquake, there will be some abnormalities in groundwater and animals. As long as we observe carefully, we will find that the groundwater is bubbling, muddy, smelly, etc. Animals are jumping around, frightened, etc. These are signs before an earthquake comes. Before an earthquake strikes, we must master the knowledge of earthquake prevention and disaster reduction and improve our awareness of self-protection; clarify evacuation routes and shock-absorbing places during earthquakes; be clear of debris in corridors and in front of doors; properly dispose of flammable and explosive items in the house, turn off gas, and cut off power. Extinguish the stove fire, etc.; put a list of family members, workplace, communication passwords, etc. in your pocket; write down your blood type if necessary.

When an earthquake occurs, there is usually 12 seconds from the start of the earthquake to the collapse of the house. At this time, you must stay calm and do the following:

When you can evacuate, evacuate quickly. Evacuate to selected safe areas in an orderly manner and avoid crowding on stairs and aisles.

If there is no time to evacuate, you should avoid the earthquake nearby and quickly go to a safe place after the earthquake. For example: At home you can hide under a bed or desk or in a smaller room such as the bathroom. In the classroom, you can hide under the desk or in the corner. Hide under chairs in theaters and restaurants.

Personnel who have evacuated or are evacuating outdoors should choose an open area to take refuge.

When avoiding shocks, pay attention to protecting your head, such as placing pillows, washbasins, schoolbags, etc. on top of your head, or protecting your head with both hands.

After an earthquake, people who were buried under collapsed buildings in a major earthquake should strengthen their confidence in being rescued, protect themselves properly, and actively implement self-rescue as long as they are conscious.

I believe that if everyone can do it, then we will no longer appear so small in the face of disasters, and we will never bow in the face of disasters.

Earthquake prevention and disaster reduction, create a better home!
