Tips of earthquake safety knowledge?

1. Taking shelter nearby during an earthquake and quickly evacuating to a safe place after an earthquake are the best ways to avoid earthquakes in an emergency. This is because the warning time during an earthquake is very short, people are often unable to move on their own, and doors and windows are deformed, making it very difficult to escape from the room; if you are in a building, it is almost impossible to escape. However, if you find early warning signs in a bungalow and the outdoors is relatively empty, you can try to run out to avoid shocks.

2. Hide indoors under or next to objects that are sturdy, difficult to tip over, and can protect the body, in a small, supported place; outdoors in an open, safe place away from buildings.

3. You should lie down to minimize the center of gravity of your body, face down, and do not press your mouth and nose to facilitate breathing; curl up your body as much as possible when squatting or sitting down; hold on to solid objects around you. , to prevent falling or injury due to body displacement and exposure to solid objects.

4. Lower your head, and protect your head and back of the neck with your hands. If possible, use items around you, such as pillows, bedding, etc., to put it on your head to protect your head and neck; lower your head, close your eyes, and To prevent foreign objects from hurting your eyes; if possible, cover your mouth and nose with a wet towel to prevent dust and poisonous gas.

5. Do not light open fires casually, because the air may be filled with flammable and explosive gases; avoid crowds and avoid crowding. This is true no matter what the occasion, on the street, in an apartment, in a school, in a store, in an entertainment venue, etc. Because, in a crowded situation, not only can you not escape danger, but you may be injured due to falls, tramples, collisions, etc.

Precursors of earthquakes

1. Groundwater anomalies

1. Abnormal changes in water level and water volume. For example, during drought periods, the well water level rises and the spring water volume increases; during wet seasons, the water level drops instead or the spring water stops flowing. Sometimes there are phenomena such as self-flow and spontaneous eruption of well water.

2. Changes in water quality. For example, well water, spring water, etc. change color, taste (such as becoming bitter, sweet), become muddy, have a peculiar smell, etc.

3. Changes in water temperature. The water temperature exceeds the normal range.

4. Others. Such as bubbling, blowing sound, well wall deformation, etc.

2. Biological anomalies

Animals are "living instruments" for observing the precursors of earthquakes. They often exhibit various abnormal behaviors before earthquakes, indicating to people that disaster is approaching. It has been found that hundreds of animals have certain abnormal behaviors before earthquakes, among which more than 20 kinds of abnormal reactions are common. The most common animal abnormalities are:

1. Fright reaction: such as large livestock not entering Circles, dogs barking, birds or insects flying, abnormal group migration, etc.

2. Inhibitory abnormality: such as the behavior becomes slow, or in a daze, at a loss; or refuses to eat, etc.

3. Changes in living habits: For example, hibernating snakes come out of their holes, rats move around during the day and are not afraid of people, and a large number of frogs come ashore to move around, etc.

3. Electromagnetic anomalies

Electromagnetic anomalies refer to the malfunction of household appliances such as radios, televisions, fluorescent lamps, etc. before earthquakes. The most common phenomena are radio failure, cell phone signal weakening or disappearance, and electronic alarm clock failure.

4. Earth Sound

Before an earthquake occurs, there are often sounds coming from deep underground. This is the "earth sound". Ground sounds usually occur a few minutes, hours, days or even earlier before an earthquake; they occur most often a few minutes before an earthquake.

5. Ground light

Ground light is also a macroscopic phenomenon before an earthquake. It has been observed before many earthquakes in China. They usually appear before or during an earthquake. , some appear several hours before the earthquake or even earlier.

There are many colors of ground light, including red, yellow, blue, white, purple, etc., and some also look like electric firelight. They have different shapes, including strip light, sheet light, spherical light, columnar light, fire-like light, etc. ,
