Because the level of earthquake prediction, especially the level of imminent earthquake prediction, is not high enough, what are the macro signs before the earthquake?

Before the earthquake, water will change, organisms will have a series of abnormal reactions, and the weather will be abnormal.

1. earthquake pioneer: on the water

Groundwater includes well water, spring water, etc. The main anomalies are bubbling, rolling, warming, discoloration, odor, sudden rise, sharp decline, sudden exhaustion or spring explosion. People summed up the proverbs about borehole changes before the earthquake. "Well water is a treasure, and pioneers will come soon." "No water, no water, no water, no water." The color and taste change slightly.

? 2. Pioneers of earthquakes: biological anomalies

For example, jellyfish in the ocean can predict storms, while rats can avoid the collapse of mines or the invasion of harmful gases in advance. In each animal, the organs of vision, hearing, touch, vibration and balance that play the primary and secondary roles may be different. Physical and chemical changes accompanying vibration (vibration, electricity, magnetism, weather, abnormal water, phlegm, etc.). ) it usually stimulates some sensory organs of some animals and causes abnormal reactions. When local gravity is deformed, some animals can feel it by balancing organs. The auditory organs of some animals can detect abnormal vibrations. Every day before the earthquake, the underground rocks are moving slowly to show their crawling movement. Because of the strong friction between the state surface and the defect surface, some people think that the low-frequency sound waves that can only be felt several to ten times per second in the defect surface of the friction surface will be lower than human hearing. People can feel sound waves more than 20 times per second, but animals can't. When they feel this sound wave, very sensitive animals will feel scared and violent. In winter, snakes come out of holes, fish jump on the water, pigs jump, deep-sea fish or shallow-water strange fish. Exceptions are like chickens flying and dogs jumping. There are many kinds of abnormal animals, including large livestock, poultry, latent animals, hibernating animals, fish and so on.

3. Pioneer of earthquake: abnormal weather

People usually describe earthquake prediction technicians as "the air in the pipeline under the pipeline". Before the earthquake, the weather was abnormal. Mainly before the earthquake, a lot of heat will be generated, and people will feel anxious and irritable. It won't rain after a long drought.

4. Pioneer of earthquake: ground acoustics

The sound on the ground is the sound made underground before the earthquake. It sounds like thunder, but heavy cars, strong winds, etc. When an earthquake occurs, sects are released from the source and spread along the ground, causing air vibration. Although this sect is very fast, it is very weak. People can only hear their own voices and move unconsciously. Therefore, the epicenter usually has a record similar to "all impacts, there is a sound underground, and the air is like tinkling boiling water". If you are in the epicenter, you will often hear a magnitude 3 earthquake. Underground sound is the result of underground rock structure and tectonic changes and the movement of liquid and gas contained in it, and a large part of sound is seismic signal. Mastering the knowledge of geosynthetics can improve the prediction and prevention of earthquakes. What caused the earthquake? What are the abnormal signs before the earthquake?

5. Pioneer of earthquake: ground light anomaly

Earthquake anomaly refers to the light emitted by the basement before the earthquake, which has various colors and is rare in daily life, but mainly appears in the form of mixed colors (such as silver, white and purple, but mainly red and white). It has belt, ball, cylinder and diffusion type. Usually, the range of light seems to be very large, and it occurs within a few hours to a few minutes after an earthquake. China Haicheng, Longling, Tangshan, Songpan and other earthquakes occurred before and after. Underground often involves earthquakes, landslides, landslides, collapses or natural phenomena such as sand blasting and jet flow. , usually occurs in fault areas or regular movement areas, and its causes are always related to other macro and micro anomalies. Has been synchronized. Perceptual movement is closely related. Geological conditions, as well as surface and atmospheric conditions, may cause different degrees of damage to people, animals and plants. The unusual report is about the ground lighting from a few seconds to a minute before the earthquake. The Haicheng earthquake, Lancang earthquake and Gengma earthquake also collected similar reports.

? The reason for the earthquake is that the earth movement protrudes or stretches between the earth plates, and people can't stop the earthquake. As long as the earth is moving, earthquakes will happen at any time. Earthquakes can happen at any time, so as long as the above signs appear, we should pay attention to them, and the sooner we know, the better.
