Isn't there any preventive measures for earthquakes? What's the difference between Tangshan earthquake and Wenshan earthquake? Why did so many people die?

First, do a good job in earthquake prediction.

There are omens before the earthquake. Now we know that this omen is: the groundwater becomes turbid, the flowers turn over, bubbles, and tastes bad; Chickens, ducks, pigs and sheep run around screaming; The mouse escaped and the fish jumped around on the water. This situation indicates that the earth's crust will bend, fold and fracture, and earthquakes will occur. At present, it is difficult for any country in the world to accurately predict earthquakes, and China's earthquake prediction can be said to be in the leading position in the world. Most earthquake predictions can show that earthquakes may occur in a certain area within a certain period of time. 1976, before the Tangshan earthquake, there was an earthquake of magnitude 6 or above in Haicheng, Liaoning Province. Before the earthquake, the government repeatedly urged all indoor personnel to be placed in the earthquake shed and repeatedly preached earthquake knowledge to minimize casualties. Therefore, the key to earthquake prevention lies in timely prediction, full preparation, and mastering the knowledge of earthquake rescue.

Second, make a family earthquake prevention plan.

Once an earthquake occurs, our power supply, water supply, heating system, transportation system, daily necessities supply system, information system and medical and health system may be damaged to some extent, affecting people's normal life. Therefore, it is necessary to make a good family earthquake prevention plan.

First of all, it is necessary to eliminate hanging objects in high places indoors, items placed vertically on cabinets and wooden frames, and change their placement positions and ways so that they are not easily knocked down and injured. At the same time, all inflammable and explosive articles should be removed. The bed should be removed from the glass window. Stick a piece of shatterproof tape on the window. Shockproof equipment should be packed in a place where it is easy to grab. In order to get out of danger, you may only have time to grab one item, and all the emergency items are in it, which will help you tide over the difficulties. These items include cash, drinking water and medicines to prevent influenza and dysentery.

Third, schools should be prepared before the earthquake.

Knowledge of earthquake prevention should be popularized in primary and secondary schools, and schools in earthquake-stricken areas should have earthquake prevention training programs. If there is an earthquake in class, the teacher should immediately give students a simple and clear instruction to close their eyes and squat under the desk. When an earthquake is likely to occur in an area within a certain period of time. Families and schools should communicate frequently. Schools with conditions in the earthquake zone should prepare disaster relief items, such as first-aid medical supplies, cold-proof and rain-proof supplies and tools. , and distributed by class or classroom until reaching individuals.

How can we protect ourselves if there is an earthquake?

Once an earthquake happens, if you are outdoors, don't go near any tall buildings or trees that may collapse, such as buildings, chimneys, telephone poles, etc. It is safer to leave bridges and interchange roads and go to open fields. Although earthquakes are natural disasters that cause casualties, they are not inevitable. If we can grasp the opportunity and use the knowledge of earthquake prevention, we can protect ourselves, such as observing the abnormal restlessness of birds and animals before the earthquake; Squatting under the table during an earthquake can reduce the damage caused by the earthquake. It can be seen that it is very important to learn earthquake knowledge.
