Earthquakes can be predicted because there are some omens, such as bees flying around; Dogs will bark, and some livestock will run around in circles; Rats move in groups ... but you have to distinguish between true and false first and run away at the first time. The following comments on some lectures on earthquake prevention and disaster reduction are carefully arranged for everyone. Welcome to check.

Lecture on earthquake prevention and disaster reduction 1 comments

I don't know if you have seen the movie Tangshan Earthquake. This film reproduces17.8 earthquake that occurred in Tangshan, China on July 28th, 1976, killing more than 240,000 people. Those scenes are frightening. They are a reflection of earthquake prevention and disaster reduction-Ping Chen Hao. 20 19 may 12 14: 28: 04, Wenchuan and Beichuan in Sichuan were suddenly attacked by a strong earthquake of magnitude 8. The earth shook, the mountains and rivers changed and were devastated. This is the most destructive and widespread earthquake since the founding of New China. The earthquake hit the land of China, and China has an area of about 500,000 square kilometers. Groups of data and pictures once again sounded the alarm for you to go. An important task in the new century is before us-"earthquake prevention and disaster reduction".

This Spring Festival, my mother took me to visit the exhibition on earthquake prevention and disaster reduction. Through this visit, I understand that animals in nature can be our "correspondents", such as: 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 droves ... if these phenomena occur, we should be vigilant and leave early. Minimize the loss. In addition, Japan, located in the northeast of Asia, has been an earthquake-prone country since ancient times. Repeated earthquake disasters and painful lessons have gradually formed a strong awareness of earthquake prevention and disaster reduction in Japan. They attach great importance to and emphasize "using the most advanced science and technology to resist natural disasters". We can learn from their advanced experience and use it for us. Finally, we can infiltrate the awareness of earthquake prevention into our lives and cultivate the awareness of earthquake prevention and disaster reduction from an early age. Through this visit, my mother smiled and said, I can be a propagandist of "earthquake prevention and disaster reduction"

Thoughts on Lecture 2 on Earthquake Prevention and Disaster Reduction

An earthquake measuring 8.0 on the Richter scale occurred in Wenchuan, Sichuan, killing nearly 70,000 people, injuring more than 370,000 people, and18,000 people were missing. What a disaster this is! The whole country grieved and the world was shocked. In order to alert the world, with the approval of the State Council, May 12 every year has been designated as the National Disaster Prevention and Mitigation Day since 20-20 years. May 12 this year is the eighth disaster prevention and mitigation day in China, with the theme of "reducing disaster risk and building a safe city".

There are inevitably various hidden dangers around us, such as typhoon, rainstorm, fire, earthquake, lightning, traffic accidents and so on. It is necessary to improve self-help and mutual rescue skills, take the initiative to prevent disasters, avoid disasters scientifically, and effectively provide disaster relief. Last week, May 12, we conducted an earthquake emergency drill to train our skills of avoiding disasters and saving ourselves. So, what should we pay attention to when an earthquake occurs?

The first and most important thing is to be calm and not to panic in any sudden emergency.

If there is an earthquake in class, students should hide under the desk as soon as possible and cover their heads with schoolbags; Students who lean against the wall should stick to the root of the wall and protect their heads with their hands; Stay away from windows to prevent glass fragments from hurting people. Students in the corridor or stairs should find a corner to squat down, protect their heads, stay away from the decorations hanging on the wall, and evacuate quickly after the vibration stops.

If you are outdoors, such as a playground, you must not run into the building to avoid danger, nor stay in dangerous places such as billboards and basketball stands. Try to concentrate in an open place. Cover your nose and mouth with towels and clothes to prevent the smoke from choking.

Of course, the probability of a catastrophe in a person's life is very small, so we should pay more attention to small safety problems and raise our awareness of prevention.

1, the stairs are safe. Strictly abide by the system of going up and down the stairs in the school. It is forbidden to walk backwards when going up and down the stairs collectively. Pay attention to order and be cautious to prevent accidents.

2. Traffic safety. Strictly abide by traffic regulations, observe the situation of vehicles before crossing the road, and take the initiative to avoid motor vehicles. Go to school on time and go home. Don't stay outside.

3. Safety against drowning, lightning, infectious diseases and food poisoning in summer.

4, correctly handle the contradictions between classmates. When students encounter contradictions, they should deal with them calmly, rationally and amicably. If they can't handle it well, they should ask the teacher for help. Never get emotional, and settle disputes by violent and illegal means such as fighting.

5. Psychological safety. Students should form positive, healthy, self-confident and optimistic qualities psychologically, seek help from friends, teachers and parents when encountering psychological problems, and don't have bad psychology of self-destruction and self-harm.

Students, life is beautiful, life is colorful, and the premise of having all this is safety. Therefore, we must always strengthen safety awareness, cherish life, strive to enhance our self-prevention ability, always pay attention to disaster prevention and mitigation, and the alarm bell will ring!

Thoughts on Lecture 3 on Earthquake Prevention and Disaster Reduction

Life is precious and priceless. We can enjoy the magnificent mountains and the magnificent sea, because we have life; We can listen to the whispers of the wind and the songs of birds, because we have life; We can feel the greatness of family, the warmth of friendship and the beauty of love, because we have life. Life is so beautiful that it is our most precious wealth.

But at the same time, life is extremely fragile. On May 20, 2008, the 12 earthquake, instantly, landslides, ground fissures, homes were destroyed and life disappeared. The familiar and warm home was torn into the ruins of Shan Ye, the innocent smiling face was taken away from the flower-like childhood, the fresh life was separated from life and death by that moment, and many dreams were brutally destroyed and buried. In the face of disaster, life seems so fragile and vulnerable.

It is precisely because life is only once that we should cherish it. As for disasters, if we can effectively prevent and protect them, I think life may be much more difficult.

For example, from 20 to 2000, May 12 of each year was designated as the national "Disaster Prevention and Mitigation Day". May 9th to15th every year is the publicity week of "Disaster Prevention and Mitigation Day". The establishment of "Earthquake Prevention and Disaster Reduction Day" is not only to commemorate the people who died in the Wenchuan earthquake in Sichuan, but also to remind us to remember the past, learn from the future and enhance the awareness of earthquake prevention and disaster reduction in the whole society. When the earthquake comes, we must be calm. Because the strong vibration lasts only a few seconds to tens of seconds, the time is short, so the method of "damping nearby" should be adopted. If you are unfortunately trapped under a building, you should keep a clear head, try to save your strength and prolong your life.

For fire, we should pay attention to the use of electrical appliances and the discharge of fireworks and firecrackers, learn to use fire extinguishers, and don't play games related to fire at will. In an unfamiliar environment, pay attention to the direction of evacuation routes, safety exits and stairs. In the event of a fire, you need to stay calm, don't panic, and use all available conditions around you to escape. If you are in thick smoke, crawl as low as possible and keep your head as close to the ground as possible.

Of course, the probability of a catastrophe in a person's life is very small, so we should pay more attention to some small safety issues and raise our awareness of prevention, such as not swimming in rivers and lakes at will; Don't enter internet cafes, so as not to affect your study, pollute your physical and mental health and personal injury; Pay attention to the safety of activities, especially in sports activities, to prevent harm to yourself and others.

However, more importantly, we should strengthen the "resilience" of life and take the initiative to undertake the mission and suffering of life. Some students have lost their reason, lost their reason, hurt themselves or others because of their study and emotional problems, and even let their lives disappear in the best time. Isn't it a pity? Therefore, we should not only prevent and reduce external disasters, but also guard against internal disasters. Once there is a problem, communicate with teachers, classmates and parents in time.

Life is irreversible. We should cherish life, live truly and live as wonderfully as possible. After every storm, let the soul feel the jointing of life. Once life comes to this world, it has a serious mission. Therefore, we should learn to prevent and reduce disasters, cherish life, seize every moment of life, and make contributions to ourselves and society with life given by God!

Thoughts on Lecture 4 on Earthquake Prevention and Disaster Reduction

Today, the theme of our speech under the national flag is-flood control and disaster reduction, safety first.

Finally, this week is the safety education week in our school. Yesterday, the city issued an urgent document. Our city has entered a period of frequent strong convective weather in summer, and disastrous weather such as short-term heavy precipitation, hail, thunderstorm and strong wind has occurred many times. According to the forecast of meteorological department, there will be two large-scale precipitation processes in our city on June 28th and June 30th to July 30th,/kloc-0, accompanied by short-term heavy precipitation, hail, thunderstorm and strong wind and other strong convective weather. In order to do a good job in disaster weather prevention, and effectively improve the ability of disaster prevention and mitigation and self-help and safety awareness. According to the requirements of the higher authorities, the school used Saturday and Sunday to timely inspect, repair and reinforce various building facilities such as school buildings, power supply lines, walls and trees, and put forward the following requirements and suggestions to the teachers and students of the school.

1, always pay attention to the weather forecast, pay close attention to the weather changes, understand and master the disaster forecast, go to school on time, arrive at school after 7: 30 am and arrive at school after 2: 20 noon. You must leave school before the bell rings. In case of thunderstorm, hail and other bad weather, I will listen to the arrangement of the class teacher during recess, try not to go out, and ask my parents to pick me up and go to school on time. Teachers should also pay attention to flood control safety when going to work.

2. The head teacher should provide targeted safety education to students in flood season through various forms, and inform parents to pick them up and drop them off on time, so as to enhance their awareness of prevention and self-help and self-care ability, so as to nip in the bud.

3. From today on, all teachers are required to arrive at key positions on time according to the schedule, command in place, earnestly take responsibility, and lead the class to inspect the positions day and night.

4. It is forbidden to organize students to go out and major activities in each class during the flood season. During the holiday period, students are not allowed to organize activities in places with flood disasters without permission.

5. In case of bad weather, don't stay under the tree to prevent lightning strikes and falling branches from hurting people, and don't get close to the place where outdoor wires fall to prevent electric shock accidents.

6, the class teacher should do a good job of class safety investigation and contradictions and disputes, found the problem, report in time.

Teachers and students, at the end of this semester, high temperature will accompany us, and heavy rain and hail will visit us from time to time. Therefore, we should be vigilant and eliminate potential safety hazards. Remember to turn off the lights, fans, etc. Unplug all power plugs and close the doors and windows before leaving school.

Students, the final exam is coming. Let's concentrate on reviewing in the storm, sharpen ourselves in the high temperature, and spend a full, safe and civilized final exam together.

Comments on lectures on earthquake prevention and disaster reduction 5

Today, Chen and I went to Shaoxing Science and Technology Museum to watch the popular science exhibition on earthquake prevention and disaster reduction, and learned some knowledge about earthquakes, which benefited a lot.

As we all know, earthquake is a very harmful natural disaster, so how did it happen? It turns out that the substances in the earth's strata will continue to move violently, thus generating great power and destroying rock formations. When this force accumulates to a certain extent, it will make the rock stratum bend and deform into a rectangle. Once the rock stratum can't bear it, it will break and move, releasing huge energy and producing strong vibration. This is an earthquake.

Earthquakes are very harmful, which can cause houses to collapse, bridges to break, dams to crack and tracks to deform. It can also make the ground crack, collapse, spray water and sand; More seriously, it can destroy natural objects such as mountains, thus causing landslides and landslides; It may even trigger a tsunami and destroy coastal areas. After the earthquake, it will also cause fires, floods and plagues. For example, in the 5. 12 Wenchuan earthquake, how many people were killed? Even if they survived, most of them lost their homes, family and friends, which is beyond our understanding. How much pain they have suffered!

Although the earthquake is very harmful, it is not unpredictable. Before the earthquake, cattle and horses could not enter the circle, jumping around, braying, fidgeting and eating less; Some pigs and sheep don't eat, they are restless and run around; Dogs bark; Chickens don't go into the nest, just cry; Ducks don't go into the water; The rabbit jumped around in panic; A few days before the earthquake, the pigeons were scared away and did not return to their nests; Bees fly away nest by nest; Rats are the most sensitive. A few days before the earthquake, the mice suddenly ran away, and some moved with mice in their mouths. Some hibernating snakes climb out of holes and climb trees; The fish swam to the shore in panic and turned white.

(1) When an earthquake occurs, if we walk in the street, we'd better put our bags or soft articles on our heads, or put our hands on our heads when there are no articles, so as to prepare ourselves as much as possible, and leave the telephone poles and fences quickly and run to a relatively open area to escape.

(2) If we are indoors, once an earthquake occurs, we must first keep a clear and calm mind, identify the vibration in time, and never jump off a building in 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.

(3) If you are buried under the ruins during the earthquake, it is dark around you and there is only a small space. Don't panic, be calm, and establish confidence in survival. I believe that someone will come to save you and do everything possible to protect ourselves. After an earthquake, there are often many aftershocks, and the situation may continue to deteriorate. In order to avoid new injuries, we should try our best to improve our environment.

We should try to get out of danger. If you can't find a way out of danger, save your strength as much as possible, and beat something that can make a sound with a stone to send out a distress signal. Don't cry, don't be impatient, don't act blindly, it will consume a lot of energy and physical strength. Try to control your emotions or close your eyes and wait for rescuers to arrive. If you are injured, try to dress it to avoid excessive bleeding.

(5) Try to make ends meet. If you have been buried under the rubble for a long time, rescuers have not arrived, or you have not heard the distress signal, you must find ways to maintain your life. You must keep water and food in the shockproof bag, try to find food and drinking water, and your urine can quench your thirst if necessary.
