Swallows are flying all over the sky on the streets of Lijiang, Yunnan. Why are swallows flying all over the sky? Is it related to the earthquake?

On the evening of August 8, a large number of swallows flew around Sanchuan Town, Yongsheng County, Lijiang, Yunnan Province, stopping on the power lines, and there were also a large number of swallows above the street. The scene was spectacular. More netizens expressed their concern and doubted whether there would be an earthquake, which caused many netizens to panic.

Subsequently, the reporter fed back the situation to the Seismological Bureau of Yongsheng County, and the staff replied that from various monitoring instruments, no abnormality was found at present. They also learned through interviews that there are a large number of swallows gathering in the local area every year, which is relatively common and has no direct relationship with the occurrence of earthquakes, and it is impossible to predict earthquakes.

And the staff of the town government also said that swallows gather here every year. Every season, there are many swallows, and every night from 7: to 9: , swallows will fly in groups.

so, why are there so many swallows flying all over the sky?

Usually, swallows fly around, mostly because of the unstable surrounding environment and other factors, and may also be related to climate change, human activities and other factors. Experts said that the situation of flying swallows in Zhumadian, Henan Province was caused by strong convective weather.

As for the similar situation that occurs every year, experts say that it is also possible that food resources are reduced or unevenly distributed, and swallows will fly at low altitude in order to find more food. Biologists also pointed out that this situation may imply food chain disorder or ecosystem imbalance, for example, related to the use of pesticides and the destruction of the ecological environment.

In another case, when a member of the swallow colony is lost, the swallows will fly at low altitude, which is to send a signal and want to establish new contacts or find a new colony. This phenomenon mainly occurs in the breeding season and migration of swallows.

can animals predict earthquakes? I looked up some information, which is also very objective. Let's take a look:

Whether animals can predict earthquakes has always been controversial. Animals do not behave consistently in earthquake prediction, that is, some animals may react and some animals do not.

But some people think that animals have the ability to sense earthquake precursors. For example, you can see the changes of geomagnetic field, groundwater level, microseisms, surface odor and air pressure, sound waves of earthquakes, and so on. These slight phone calls may affect the behavior of animals, and they will have abnormal reactions before the earthquake.

Therefore, whether animals can perceive earthquake precursors or not should be treated with caution. Although some animals do have abnormal behaviors before earthquakes, they are only used as reference and cannot be used as an important basis. In the past, people would sum up the laws according to some phenomena. At that time, there were no advanced scientific instruments, and earthquake early warning was based on some abnormal phenomena before.

The seismologist Joseph once summarized the abnormal behaviors of animals. The earthquake may cause abnormal behaviors of animals, but not all the abnormal behaviors of animals are caused by the earthquake.

I'll give you a simple example, so that everyone will understand: It's like studying to get into Tsinghua University, but not everyone studies to get into Tsinghua.

I'm also very emotional here. Although the earthquake is terrible, we can't judge whether the earthquake is coming simply by the abnormal behavior of animals. This is not a very reliable method.

whether there is going to be an earthquake or not, we should believe in scientific and technological means. We can't cause unnecessary panic by spreading false information, and we can't rely entirely on the reaction of animals to carry out earthquake early warning and prevention. We must combine them as a whole for reference, and then take corresponding measures.
