Earthquakes are preceded by omens. Now we know this omen is: the groundwater becomes muddy, turn flowers, bubbling, tasteless; chickens, ducks, pigs and goats running around screaming; rats fleeing, fish jumping on the water surface. This situation indicates that the earth's crust will be bent, wrinkled and fractured, and an earthquake will occur. At present, it is difficult for any country in the world to accurately forecast earthquakes, and China's earthquake forecasting can be said to be in the world's leading position. Most of the earthquake forecast can point out that a certain area in a certain period of time may occur. 1976, before the Tangshan earthquake, Liaoning Province, Haicheng area had a magnitude 6 or more earthquake, before the quake, the government has repeatedly urged all the indoor people resettled in the seismic shed, and repeatedly preach the earthquake know only, the result is that casualties have been reduced to a minimum. Therefore, the key to preventing earthquakes lies in timely forecasting, adequate preparation, and knowledge of earthquake rescue.
Two, the development of family earthquake prevention program.
Once an earthquake occurs, it may make our power supply, water supply, heating system, transportation system, the supply system of necessities, information system, and medical and health care system be damaged to some extent, affecting the normal life of the people, so we should make a family earthquake prevention plan.
First of all, we should exclude the hanging objects in the high places of the room, and the objects placed vertically on the cabinets and wooden shelves, and change the position and way of placing them, so that they are not easy to be shaken down and hurt people. At the same time to remove all flammable and explosive items. The bed should be moved to a place far away from the glass window. Put shatterproof tape on windows. Shock-absorbing gear bags are placed where they can be easily grabbed. In order to get out of danger, you may only have time to grab one item, emergency items are included and it will help you get through. These items include cash, drinking water, and medicines against flu and dysentery, among others.
Third, schools should be prepared for an earthquake.
In secondary and elementary school should popularize knowledge of earthquake prevention, schools in earthquake zones should have a program of earthquake prevention training, if an earthquake occurs while a class is in session, the teacher should immediately give a simple and clear instruction to students to close their eyes on the spot and crouch under their desks. An area where an earthquake may occur at a certain time. Families and schools should communicate frequently. Schools in earthquake zones that are in a position to do so should have disaster relief items, such as first aid medical supplies, cold and rain supplies, tools, etc., and distribute them by class or classroom until they are in the hands of individuals.
How to protect yourself if an earthquake occurs?
In the event of an earthquake, if you are outside, do not approach buildings, chimneys, utility poles, or any other tall buildings or trees that may collapse, and leave bridges and overpasses and go to an open field where it is safer. Although earthquakes are natural disasters that cause deaths and injuries to people, they are not unpreventable. If you can seize the moment, the use of earthquake knowledge can protect themselves, such as the earthquake occurred before the observation of birds, animals, abnormal agitation; crouching under the table when the earthquake occurred can reduce the damage caused by the earthquake. It can be seen that learning about earthquakes is very important.
