Will Mianzhu Bat be affected by the Luding earthquake?

At 12:52 on September 5, 2022, a magnitude 6.8 earthquake occurred in Luding County, Ganzi Prefecture, Sichuan Province, with a depth of 16 kilometers. At present, the earthquake has killed 46 people, and the national earthquake emergency response level has increased to secondary.

The earthquake affected the Quartet, and everyone's gaze turned to Sichuan's earthquake. But I never thought that a group of bats nearly 300 kilometers were rushed to the hot search.

On the day before the earthquake, a large number of bats flew over in Mianzhu, Sichuan, causing many citizens to watch. Afterwards, the relevant departments responded to normal and natural phenomena, and in previous years.

Even though science popularizations from all walks of life were broken and shattered, many netizens still did not want to believe that they insisted that the bats of bats would "predict" the occurrence of the Luding earthquake in advance and collectively "run the road."

Coincidentally, it is not uncommon for this kind of news that this is "abnormal before earthquake animals" after the earthquake. Of course, more common animals are considered to be a precursor to the earthquake, but there is no earthquake.

The statement about animals can predict earthquakes for a long time.

As early as 373 BC, a few days before the destructive earthquake occurred, the mouse, weasel, snake, and crickets left the Greek city Heris and went to a safe zone.

From the centuries since then, reports on the "predictive earthquake" of animals appeared from time to time -the catfish moved violently, the chickens stopped eggs, and the bees left the bee nests in panic ... almost all kinds of common animals were reported Pass. Countless pet owners claimed that they had witnessed the strange behavior before the cats and dogs shook on the ground -barking or complaining for no reason, or showing signs of tension and uneasiness.

Can animals predict earthquakes?

Please believe that scientists have started professional research in this area very early.

No relationship between animal abnormalities and earthquakes

Not only in China, there are many countries such as Japan and the United States. There are also a large number of people who believe that abnormal animal behavior is a precursor to the earthquake, which is in sharp contrast to the view of natural science.

American earthquakers have always been skeptical of this. Although the animal behavior recorded in the case before the earthquake was abnormal, the US Geological Survey stated that it has never established a repeated connection between the specific behaviors of the animal and the occurrence of the earthquake. In the 1970s, the U.S. Geological Survey conducted some research on animal predictions, but did not draw any specific results. They faced a large number of "anecdotes", but they could not make related contacts with the time and place where the earthquake occurred.

Animals will respond to many things -hunger, defending their own territory, mating, and predators -they believe that it is difficult to conduct comparison research to obtain accurate animal "predictive signals".

An once popular theory claims that there is a correlation between the loss of pet ads in San Jose Mercury News and the date of the earthquake in the San Francisco Bay Area. However, in 1988, a comprehensive statistical analysis of this theory published in "California Geology" was published in 1988 that there was no such correlation.

In Japan, more earthquakers who are influenced by culture and study abnormal phenomena of nature must be more. The "earthquake cloud" we often say today originated in Japan.

The Japanese legendary earthquake was caused by a catfish in the deep sea, and many earthquakes often occurred in the sea area. Most of the targets that they were "abnormal before the earthquake" were deep -sea fish. Based on a scientific and responsible attitude, scientists have prepared a database with deep sea fish to reveal the phenomenon of the sea, and conduct statistical investigations on such information.

Destroy big catfish and the earthquake retreats! retreat! retreat!

Because deep -sea fish appearance is relatively rare, newspapers are often reported in local newspapers in Japan. The author builds a report database from newspapers, academic articles and marine museums. In this study, it focuses on fish that are generally considered to be related to earthquakes, such as the emperor with fish and slender band fish, and then evaluate the incidence of earthquakes after the occurrence of deep -sea fish.

As a result, no time -space relationship between deep -sea fish and earthquakes were found.

Researchers believe that the occurrence of deep -sea fish in folk legends indicates that earthquake occurs and is superstition.

Animal abnormalities are not a little scientific?

For so many years and so many public recognition that animal abnormalities can predict earthquakes, will it not be a little scientific?

The abnormal behavior of animals that occur within a few seconds before the earthquake has scientific reason.

Because after the earthquake, the smaller P -wave spreads the fastest, and it may be perceived by some sensitive animal animals. Later, the Swap, which has a greater destructive earthquake, has a feeling of more talents.

Some people have reviewed the publications from 180 pre -earth animals (time span from 1756 to 2015), analyzed data such as earthquake magnitude, earthquake distance, and front earthquake activities. Regarding, these animals can perceive the vibration that humans cannot feel, and therefore abnormal behavior.

One of the research results from above: black spots are the report position of animal abnormal behaviors. The gray point is a seismic position greater than 6 from 1900 to 2012. This picture can only show that people who have many earthquakes have observed more animal abnormal phenomena and cannot prove that animal abnormalities can predict earthquakes

As for animals a few days before or a few weeks before the earthquake, the upcoming earthquake, that's another matter.

The supporters of the animal prediction of earthquake claim that animals have abnormal sensations and reactions to the environmental and physical chemical parameters in the process of giving birth to the earthquake, such as geomagnetic and land and so on.

However, in modern earthquake sciences, the seismic monitor and precursor monitor we use can capture changes in vibration and physical chemistry more keenly than animals.

As early as the animal adopted action, the data changes and the record of these parameters had been displayed on the computer of the seismologist. At present, we still have not solved the problem of earthquake forecasting, and naturally it is even more unable to use elusive, difficult to quantitative animals. The abnormal behavior.

Earthquake observation of the earthquake monitor in the mountain cave

In addition, the statement of animal abnormal behaviors is a little psychological, which is the "psychological focus effect". When people encounter major disasters such as earthquakes, they often recall various details before the incident, and tend to think that these details are "rare and abnormal". If nothing happens, people will not remember this strange behavior.

And these "rare and abnormalities" often happen, but people do not usually observe and remember.

Faced with unpredictable earthquake disasters, everyone wants to do their best to reduce disaster losses as much as possible.

But spreading rumors can only increase fear and drowns the correct information. I hope there will be similar information next time. You can distinguish between right and wrong and drink: Hi, they can't wait for the number!
