Small common sense of earthquake safety knowledge?

First, it is a better way to prevent shock, and evacuate to a safe place quickly after the earthquake. This is because the earthquake warning time is very short, people often can't act independently, and it is very difficult to run out of the room because of the deformation of doors and windows. If you are in a building, it is almost impossible to get out. However, if the early warning phenomenon is found in the bungalow and the outdoor is relatively empty, you can try to run out of the shock absorber.

2. Hiding under or beside a solid, hard-to-topple, body-covering object indoors, in a narrow and supportive place; Outdoor away from buildings, empty and safe place.

Third, try to lower your body center of gravity, face down, and don't press your nose and mouth to facilitate breathing; Try to curl up when squatting or sitting down; Grasp the solid objects around you to prevent falling or injury due to body displacement and contact with solid objects.

Fourth, bow your head and protect your head and neck with your hands. If possible, put things around you, such as pillows and bedding, on your head to protect your head and neck. Bow your head and close your eyes to prevent foreign bodies from hurting your eyes; If possible, cover your nose and mouth with a wet towel to prevent dust and toxic gases.

5. Don't light an open flame casually, because there may be flammable and explosive gases in the air; Avoid crowds and don't crowd around. No matter what occasion, street, apartment, school, shop, entertainment place, etc. Because, not only can you not walk out of danger in the crowd, but you may also be injured by falling, trampling and colliding.

Extended data:

Earthquake precursor phenomenon

First, groundwater anomalies.

1, abnormal change of water level and quantity. For example, during the dry season, the well water level rises and the spring water volume increases; In the rainy season, the water level drops or the spring stops flowing. Sometimes the well water flows by itself and sprays by itself.

2. Changes in water quality. For example, well water and spring water change color, taste (such as bitter and sweet), turbidity and odor.

3. The change of water temperature. The water temperature exceeds the normal range.

4. others. Such as flower turning and bubbling, jet ringing, shaft wall deformation, etc.

Second, biological anomalies.

Animals are "living instruments" for observing earthquake precursors. Before the earthquake, they often have various abnormal behaviors, which indicates the coming disaster to people. It has been found that hundreds of animals have some abnormal behaviors before the earthquake, among which there are more than 20 kinds of common abnormal reactions. The most common animal abnormal phenomena are:

1, panic reaction: such as large livestock not entering the circle, dogs barking, birds or insects flying around, abnormal group migration, etc.

2. Suppress abnormality: If the behavior becomes slow, or stunned, I am at a loss; Or refuse to eat, etc.

3, life habits change: such as hibernating snakes out of the hole, mice are not afraid of people during the day, a large number of frogs ashore.

Third, electromagnetic anomalies.

Electromagnetic anomaly refers to the failure of household appliances such as radios, televisions and fluorescent lamps before the earthquake. The most common phenomena are radio failure, cell phone signal weakening or disappearing, and electronic alarm clock failure.

Fourth, the voice of the earth.

Before the earthquake, there were often sounds coming from deep underground, which was the "earth sound". Earthquakes usually occur minutes, hours, days or earlier before earthquakes; It appears at most a few minutes before the earthquake is about to happen.

Five, the ground lighting

Terrestrial light is also a macroscopic phenomenon before the impending earthquake, which was observed before many earthquakes in China. They usually appear before or during the impending earthquake, and some appear a few hours or earlier before the earthquake.

There are many colors of the earth's light, including red, yellow, blue, white and purple, and some are like electric fire. They have different shapes, such as strip lights, sheet lights, spherical lights, column lights, fire lights and so on. 、
