A school of fish jumped out of the water in Jingzhou, Hubei, saying "an abnormal animal will inevitably cause disaster", is it a precursor to an earthquake?
A few days ago, a rare "animal anomaly" phenomenon appeared in Honghu Lake in Jingzhou, Hubei. According to the video taken by witnesses, the fish in the lake scrambled to jump out of the water, fell into the water and then jumped out again, as if there was something terrible in the water that made them want to escape. Before the Sichuan earthquake, such anomalies had also occurred in many places in Sichuan. Therefore, many local residents expressed concern, fearing that a major earthquake will occur in Hubei before long. After witnesses posted the video on the Internet, netizens said that this is likely to be an "earthquake precursor" and reminded the local people to pay more attention. In this way, the local people are more worried and feel that this is not a good thing. Phenomenon.
So, is the Jingzhou fish jumping out of the water repeatedly, is it really an "earthquake precursor"? Is the large-scale abnormal behavior of animals really related to the imminent natural disaster?
Before paying attention to the messenger of singularity and grasping the latest scientific information to answer this question, let's briefly review the earthquake situation in Hubei history. Over the past 2,000 years, there have been 33 recorded earthquakes of magnitude 5 or above in Hubei. At the same time, from the perspective of Hubei's geographical location, Hubei is located in the "middle and lower reaches of the Yangtze River Seismic Belt". The characteristic of this seismic belt is that if an earthquake occurs, it will generally be an earthquake with a shallow epicenter and strong destructiveness. Earthquakes of magnitude 6 and above are rare, but as long as an earthquake of magnitude 5 or above occurs, it can cause damage to the epicenter.So, in this case, this time the fish in Jingzhou, Hubei jumped out of the water, are they telling people that an earthquake will soon occur in Hubei?
Actually, the answer is not so. Although Hubei is indeed in the earthquake zone, Hubei is still a very safe province in my country. On the one hand, the current houses have building requirements for earthquake resistance and earthquake resistance. An earthquake of about magnitude 5 will theoretically not cause anything. dangerous. On the other hand, the probability of a strong earthquake of magnitude 6 or above in Hubei is very small. In the past 2,000 years, there have only been two strong earthquakes of magnitude 6 or above, one in 788 AD and one in 1932. After all, a magnitude 6 earthquake will occur only after a thousand years. In addition, the "Jianghan Earthquake Belt" where Jingzhou, Hubei Province is located is itself one of the least active seismic belts in my country. There will only be 2-3 earthquakes a year at most, and the magnitude of the earthquake is below 3, so people cannot detect it at all. arrived. Therefore, a long time ago, the Hubei Earthquake Administration had stated: Hubei is a very safe place, and the possibility of an earthquake of magnitude 5 or higher here is less than 1 in 10,000, which also means that this time the fish in Jingzhou, Hubei jumped Out of the water, it is not an "animal anomaly" phenomenon, nor a "earthquake precursor", but another reason, and you don't need to worry about it.So, what is the "fish jumping out of the water" phenomenon?
Actually, there are many possibilities for the fish to jump out of the water one after another. First of all, if there are natural enemies in the water, or unknown foreign objects, including the noises made by people on the shore, it will cause disturbance to the fish, making them mistakenly believe that danger is approaching, producing a panic-like stress response, and instinctively jumping out On the water, trying to avoid danger. Secondly, if there are fish in the water infected with parasites, or if there is an infectious disease in the fish, the infected fish will jump out of the water because of physical discomfort. I hope that through this repeated jumping, I can get rid of my body. parasites, or relieve itching. This situation is relatively common in artificially farmed fish ponds. Generally, when farmers see such a scene, they will check the fish and put in drugs in time to avoid a large number of fish deaths. In addition, changes in water temperature can cause schools of fish to jump out of the water. Because fish are warm-blooded animals, they have very high requirements for water temperature. Whether it is too hot or too cold, it may cause the fish to have a stress response, especially when the temperature suddenly drops, or before the arrival of heavy rain, at this time, The oxygen content in the water begins to decrease, and the fish cannot get enough oxygen, and they will jump wildly to avoid their own hypoxia and death. In addition, during the breeding season of fish, there will be interactions between male and female fish, especially in the early morning. This phenomenon will be very obvious. They will continue to jump and swim on the water surface. It is also a natural biological phenomenon to reproduce in a playful way.So, what caused the Jingzhou fish to jump out of the water?
After listing and analyzing the above reasons, the messenger believes that the reason why the fish in Jingzhou, Hubei jumped out of the water this time is probably a normal phenomenon in the breeding season. The eyewitness saw it in the early morning, and early autumn is also the main season for fish courtship and mating. Therefore, the scene seen by the eyewitness is very likely that the fish in the lake are competing for mates and spawning and fertilizing. Jump and play on the water. In addition, if the number of fish in the water is too large, causing them to be too densely distributed, or at dusk, a large number of plankton gather on the water surface, which will also cause the fish to jump out of the water. Of course, the above possibilities Sex is also a natural biological phenomenon, and has nothing to do with the occurrence of natural disasters such as "earthquakes".At this time, the question arises. The ancients often said that "an abnormal animal will inevitably cause disaster". Is this sentence reasonable?
Actually, the statement that "anomalies must lead to disasters" is unscientific in the eyes of scientists and geologists alike. Experts from the Sichuan Earthquake Administration said that predicting earthquakes through animal anomalies is the experience of predecessors. In the age when ancient science was not yet developed, people could not use science to explain various natural phenomena, so they thought of the "earthquake before the earthquake". Animal anomalies" phenomenon, a set of rules finally obtained through sorting and analysis, of course, this law is of no value at present. In fact, most of the animals come together because of seasonal migrations, increased numbers of natural enemies, weather changes, and difficulties in foraging, all of which have nothing to do with earthquakes. Therefore, everyone does not need to see the fish jumping out of the water, and think it is an ominous omen. We still need to look at the problem from a scientific point of view, and not let ourselves fall into panic. So friends, do you think animals can predict earthquakes?
