Swallows are flying in the streets of Lijiang, Yunnan. Why are swallows flying everywhere? 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 line, and there were also a large number of swallows above the street. The scene is spectacular. More netizens expressed concern and doubted whether there would be an earthquake, which caused many netizens to panic.

Subsequently, the reporter reported the situation to the Earthquake Administration of Yongsheng County, and the staff replied that from various monitoring instruments, no abnormalities were found at present. They also learned through interviews that a large number of swallows gather 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.

Moreover, the staff of the town government also said that there are swallows gathering here every year, and there are many swallows in every season. Swallows fly around in groups from 7: 00 to 9: 00 every night.

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

Swallows usually 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 Feiyan in Zhumadian, Henan Province was caused by strong convective weather.

For similar situations that occur 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 point out that this situation may mean food chain disorder or ecosystem imbalance, for example, related to the use of pesticides and the destruction of the ecological environment.

On the other hand, when a swallow group loses a member, the swallow will fly at low altitude, which is to send a signal to establish new contacts or find a new group, and this phenomenon mainly occurs during the breeding season and migration of swallows.

Can animals predict earthquakes? I looked up some information, objectively speaking. Let's see:

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 may not.

However, some people think that animals have the ability to sense earthquake precursors. For example, the changes of geomagnetic field, groundwater level and microseisms, as well as the changes of surface odor and air pressure, and the sound waves of earthquakes. These slight phone calls may affect the behavior of animals, and there will be abnormal reactions before the earthquake.

Therefore, whether animals can perceive earthquake precursors should be treated with caution. Although some animals did behave abnormally before the earthquake, it was only used as a reference and could not be used as an important basis. In the past, people would sum up laws according to some phenomena. At that time, there were no advanced scientific instruments, and the earthquake early warning was based on some abnormal phenomena before.

Seismologist Joseph once summed up the abnormal behavior of animals. Earthquakes may cause abnormal behaviors of animals, but not all abnormal behaviors of animals are caused by earthquakes.

Let me give you a simple example to make you understand: Just like you have to study to get into Tsinghua, not everyone studies to get into Tsinghua.

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

Whether there will 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 for earthquake early warning and prevention. We must learn from them as a whole and then take corresponding measures.
