Four-level earthquake prevention and disaster reduction composition 450 words 1 students, have you thought it over? What are the disasters? What if there is a disaster? Let me tell you something about it.
Disasters include earthquakes, fires, car accidents and floods. Some are caused by ourselves, and some are natural disasters, which can be prevented.
Do you remember? Dehui Trade City was caused by a fire. In order not to have a fire, we should not play with fire and stamp out the cigarette butts smoked by our parents, otherwise it will lead to great disaster.
5. 12 earthquake affected children in Sichuan. Although the earthquake didn't happen because we didn't want it to happen, China has implemented the "earthquake-resistant housing" project. Bought us insurance. Let me tell you the "three noes" during the earthquake: don't panic, don't run around and don't listen to the command.
When there is a flood, you should be calm, obey the command of rescuers, don't run around, and don't refuse to leave for money. Life comes first!
We can also prevent drought, which is caused by human destruction of the ozone layer. As long as we don't litter and spit everywhere ... in fact, these little things can prevent drought.

On May 2, 2008, at 6: 438 and 4: 28, an earthquake of magnitude 8.0 occurred in Wenchuan County, Sichuan Province, China. In just a few seconds, the area around Wenchuan was in ruins. 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. ...
Earthquakes are unpredictable If human beings can predict the time, magnitude and region of earthquakes, and if we learn to save ourselves, then many lives will not disappear. We are not reconciled. Although we can't predict the coming earthquake, we can arm ourselves with the knowledge of earthquake prevention to accurately prevent and reduce the losses caused by the earthquake.
So, what should we do when the earthquake disaster comes?
People can't predict the disaster, so we can only rely on ourselves to prevent the losses caused by the earthquake.
Four levels of earthquake prevention and disaster reduction composition 450 words 3 earthquake prevention and disaster reduction Sichuan area since 7. The earthquake of magnitude 8 made people panic, but everyone didn't wait for death, and people from all directions came to support. This is called: if one party is in trouble, all parties will support it. Now I'm going to tell you how to prevent earthquakes and reduce disasters. If an earthquake comes, how to avoid it?

1. If you are in the classroom, you must follow the teacher's instructions, hide under the desk and pay attention to protecting your head.
2. If you are going to physical education class, avoid tall buildings and don't get hurt.
3. If you are in the cinema, you should hide under the viewing chair to absorb shock, avoid hanging lamps, air conditioners and other items on the ceiling, protect your head with things, and listen to the commanders to evacuate the scene.
4. If there is an earthquake in the shopping mall, avoid glass cabinets, commodities, billboards, lights and other objects.
5. If there is an earthquake in the bus, hide under the chair or squat down, keep the center of gravity stable and hold the handrail.

If before the earthquake, horses and other livestock will break free from the reins and run out crazily; A hibernating snake will come out of the hole; Bees will fly in horror; Dogs will bark, and some domestic animals will run around in circles; Rats will act in a hurry. If this situation is found, it should be reported to the Seismological Bureau in time to prevent it from leaving as soon as possible.

Fourth grade earthquake prevention and disaster reduction composition 450 words 4 earthquake, this word is very familiar to us. Causing serious accidents such as house collapse and casualties. How should we prevent earthquakes?
There are two major seismic zones in the world: the Eurasian seismic zone and the Pacific Rim seismic zone. The Eurasian seismic belt spans Europe and Asia, and the Pacific Rim seismic belt is a seismic belt around China, Japan, the United States and some small island countries at sea. These two seismic zones just put China in the middle, so there are more than a dozen earthquakes in China every year, which bring unexpected losses to human beings.
We should calmly face the sudden earthquake and not listen to rumors. When there is a small earthquake before the earthquake, you should quickly turn off the heating, kettle, gas and power supply, then hide under solid furniture such as tables, chairs and beds, and then run to parks, squares, playgrounds and other wide places after the earthquake, keep your head down and pay attention to the above preventive measures, so as to survive in the earthquake.
A long time ago, China had an earthquake prevention organization, which is equivalent to the current Seismological Bureau. During the Eastern Han Dynasty, scientist Zhang Heng also invented the "seismograph", which pushed China's scientific career to a peak. We should learn from Zhang Heng's scientific spirit, not believe in cults and rumors, and use scientific methods to prevent earthquakes, prevent earthquakes and reduce disasters, so as to build a better tomorrow for our country.
Disasters are people's greatest enemies, such as earthquakes, tsunamis and fires. Disasters will bring great losses to people, including human life, so all of us should know the knowledge of earthquake prevention and disaster reduction and learn to protect ourselves.
The school organized many activities for all of us to learn the knowledge of earthquake prevention and disaster reduction, such as asking the uncle of the fire brigade to explain the knowledge of escape in case of fire, conducting escape drills in case of fire, covering your mouth with a towel in case of fire, standing in a row, and running quickly to the playground from the safe passage. The school also invited the traffic police uncle to explain the traffic safety knowledge to all of us, so as to avoid traffic accidents for all of us.
Some disasters can be prevented, and all our schools have some unsafe factors. For example, the stairs of the school are crowded into a pot of porridge every time they go downstairs, which is the most prone to trouble. The fan in the classroom, when it is turned on to the maximum, swings on the roof as if it were about to fall off. Every time the classroom door is windy and slams, the glass on the door can be shattered. Chasing and fighting in the corridor, it is easy to accidentally fall and hurt each other. These are all unsafe factors around us and can be prevented. Please read the following:
1, don't chase and fight at school.
Go downstairs one by one, don't crowd together.
Don't slam the door when it is windy, but hold the door with a chair.
We should all protect the public facilities of the school. Caring for the school means caring for ourselves and making our school better!
