Most people will react, and it is best to add how long it usually happened before the earthquake.

Will human beings be abnormal before the earthquake? Experts say that this abnormal reaction of human beings may exist, and the specific performance and sensitivity vary from person to person, but it cannot be verified. According to Sun, some people also had obvious abnormal reactions before the earthquake, such as inexplicable panic and fear a few minutes or more before the earthquake. 1938+0976 After the Tangshan earthquake, some people claimed that they were extremely flustered and felt when the earthquake was coming. Even fight all over. It is reported that some amateur earthquake prediction researchers often think that an earthquake is about to happen according to their abnormal feelings. "This abnormality varies from person to person, maybe only a few people," he said. "Maybe some people can have this abnormality, but we don't know."

As for how to explain these problems, he said: "It is difficult to explain. Some people are far away from the earthquake zone, but there will be anomalies before the earthquake. " He told reporters that there was once a person who felt uncomfortable in his brain and found an earthquake. Later, as soon as he felt uncomfortable in his brain, he went to the hospital to do EEG, and then predicted the earthquake according to the EEG he did every time. An earthquake of magnitude 5.9 occurred in Dongwuzhumuqin Banner, Inner Mongolia. About a week before the earthquake, the man thought that an earthquake might happen in Liaoning in the next few days according to his abnormal reaction. When the earthquake occurred, there were obvious earthquakes in some areas of Liaoning. Another person can feel the difference of abnormal electromagnetic waves emitted from the deep crust, and can judge the earthquake time and analyze the magnitude (approximate area) of the earthquake in combination with the terrain. Three or four days before the earthquake,

Sun believes that one of the main problems of human abnormal response before the earthquake is that there is no way to verify this abnormality of human beings. "The abnormality of animals can be proved, but there is no way to prove the abnormality of human beings before the earthquake." He said that some people will have abnormal feelings, which is for sure, because the human body is different, and some people are very easy to accept the changes before the earthquake. For example, a few days before the earthquake, electromagnetic waves were abnormal, which is for sure.

Why did such animal anomalies occur before the earthquake? Why is the abnormal reaction of human not as prominent as that of animals? How to effectively prevent earthquakes by using animal anomalies before earthquakes?

Sun believes that the ultimate survival of living things in the long evolution process of hundreds of millions of years is the result of natural selection. Their survival is closely related to the whole earth environment, and earthquakes and other activities on the earth will have an impact on the creatures living in them.

In the process of earthquake preparation, many physical and chemical changes will occur, which are directly or indirectly related to animal anomalies. He explained to reporters that the abnormality of some animals is mainly directly related to the sensory activities of animals, which may be due to the changes of sound, light, electricity, ground temperature and smell, leading to changes in the living environment of animals and directly stimulating the relevant sensory organs of animals. For example, before the Haicheng earthquake, the ground temperature in the earthquake area increased by 2~3℃. This may cause hibernating snakes to come out of their caves. For example, before the earthquake, in-situ stress will deform and rupture the caves where animals live, causing the invasion of groundwater or underground toxic gases, directly affecting cave animals and leading to their abnormal reactions. The abnormality of other animals may be due to the change of electromagnetic field and electrostatic field before the earthquake, which directly stimulates the central nervous system of animals, thus leading to the sudden disorder of its central nervous system function. For example, the abnormality of electromagnetic waves may directly stimulate the central nervous system of mice and make them live in groups.

"The physical and chemical phenomena we observed before the earthquake were accompanied by animal anomalies. If we draw the distribution of animal anomalies on the map, we can find that they are consistent with other anomalies, "Sun said.

As for why the abnormal reaction of human beings before the earthquake was not as prominent as that of animals, he thought it might be because some organs of animals were developed. Take the earth sound as an example. Due to factors such as sound pressure and frequency band, it is likely that some earth sounds that are not within human hearing range can be heard by some animals. In addition, although the auditory sensitivity of some burrowing rodents is similar to that of human ears, their sensitivity to sound reverberation and resonance can be greatly increased. Similarly, some

Since the abnormal response of human beings before earthquakes is not as sensitive as that of animals, how to make full use of animal anomalies to effectively prevent earthquakes? Sun told reporters that the prediction of 1975 Haicheng earthquake is the only successful earthquake prediction in the world so far. In the whole prediction process, it is very important to carry out mass monitoring and mass prevention before the earthquake and carry out a lot of popular science propaganda to let people know that there will be animal anomalies before the earthquake. Therefore, a large number of animal anomalies will immediately arouse people's vigilance the day before the earthquake. "If you can master some knowledge about earthquakes,
