Self-defense before the earthquake,
knowledge about family earthquake prevention and disaster reduction, family fire safety knowledge
Pre-earthquake self-defense refers to the areas where there are backgrounds of medium and short-term earthquake predictions. Before the impending earthquake, the masses spontaneously adopted simple and effective measures for earthquake-resistance and earthquake-resistance measures according to the discovered macroscopic abnormalities.
Earthquakes at home and abroad have demonstrated that macroscopic anomalies such as groundwater, animal behavior, weather, and crustal deformation have occurred before most strong earthquakes. This is a response to drastic changes in various physical and chemical fields in the seismogenic area. Because of its characteristics of regional distribution, large quantities, and time concentration, it is easy to be discovered by the masses of people in extreme earthquake areas.
First, the use of animal anomalies for self-defense
In the Tangshan Earthquake, examples of self-defence using animal anomalies indicate that animals are "live instruments" that predict earthquakes. Cave animals are easy to perceive the subtle changes in the depths of the ground. Therefore, the abnormalities of the rats are numerous and obvious. In addition, the dogs are the Savior; the livestock alarms, both ancient and modern, are known as stories. During the Tangshan earthquake, there were few breeders dead and injured, mostly because the livestock were not quiet at the time of the earthquake and the keepers were intentionally or unintentionally spared their misfortune in dealing with livestock. It can be seen that information on animal anomalies before major earthquakes exists and can be used by people.
Second, the use of groundwater anomaly for self-defense
The sudden change of groundwater before the earthquake is very precious precursor information. However, the appearance of such obvious anomalies is often very short-lived. Therefore, to be able to detect these anomalies in a timely manner and use them for self-defense not only needs vigilant minds, correct judgments, but also timely and effective actions.
Some well water anomalies occur earlier and may be related to the structural locations of these wells. People vividly call these places “sensitive points” or “windows.” Penetrating the underground dynamics through this “window” is a very vivid metaphor, and it is also a place we should pay special attention to in the earthquake self-defense.
Pre-warning and shock absorption
Those who live in cottages, if they are awake at the time of the earthquake, find that the early warning phenomenon is relatively early and that it is easy to open the doors and windows, and it is entirely possible for the crew to immediately run out of the house. The roommates should take care of each other. Those who come back and come back to rescue their loved ones generally do not have the conditions to run out again, and they should adopt indoor suspension methods.
Second, indoor suspension sensitive and decisive
Those who live in cottages, if they find that the early warning phenomenon is relatively late and the ground has been clearly shaken, should adopt an indoor suspension method to quickly lower the center of gravity, and hide under the edge of the curtain and the solid furniture or wall corner. Active shock and shock are not the same.
Third, the machine equipment is favorable shock absorber
In public places such as collective canteens, theaters, conference halls, and large factories, there are earthquakes, people have many narrow doors, and it is inconvenient for them to run out. The door is often a fragile part of the building, and it is easy to cause casualties. Large buildings generally have better seismic performance, and there are more solid machinery and equipment in the room. Therefore, people who are closer to the separation door in an earthquake can wait for an opportunity to run out. Generally, the approach of using indoor near-surface suspension is safer.
Fourth, reduce the focus of the small open space
In the natural warning time of more than ten seconds, it is impossible for the high-rise of the building to survive the shock. The result is most likely to be congested at the stairs where the structure of the building is weak. Even if one can live out, it is often too late to avoid the collapse of the collapsed building. A survey of the survivors of the Tangshan earthquake revealed that the most effective way for impending earthquakes is to quickly avoid the indoor shock absorbers that are prone to triangular space formation. Bathrooms, kitchens, small bays, and corners on the inside are relatively good places for shock absorbers.
V. Once you have crossed the barriers and avoided the new ones, you must move away from the buildings in time to avoid being buried again. As the aftershocks continue after the major earthquakes, buildings that have not completely collapsed should not be easily approached, let alone into dangerous buildings.
