August 21, 1986 , Lake Neos in Cameroon, Africa killed more than 1,700 villagers in surrounding villages overnight. Many villages were directly destroyed and no survivor was found. What is even more creepy is that all the dead died in their sleep, and " Killing Lake " killed people invisibly in silence.
When relevant institutions came to check the situation, they found that the lake water turned into a terrifying blood orange color, a large number of animals died, and the lake's radius of 20 kilometers turned into no-man's land , and only plants and buildings still exist.
Before this disaster, Lake Neos, as a famous tourist attraction, was once very prosperous and was an important income-generating project for Cameroon . Why did Lake Neos suddenly become a "killer lake"? How do lakes kill people?
Sudden disaster
Lake Neos is located on the plateau of Cameroon. It has beautiful scenery and clear lake water. It is a very famous natural scenic spot and has attracted many tourists to visit. In addition to the natural beauty, the soil and natural resources around Lake Neos are also very rich. People living nearby can live on the two paths of agriculture and tourism, which can be considered as having no worries about food and clothing.
If we look at it now, Lake Neos is definitely a good place that can bear many people and meet people's basic production and living needs. However, in in the 1970s and 1980s, the development in Africa was not as complete as it is now, many infrastructure construction was not complete, and the location of Lake Neos was too remote, so there was not much room for development.
The people living in the local area have lived in and passed down for hundreds of years, and have intermarriage and connections with each other, and seeking survival among this lake together. By relying on the mountains to eat the mountains and water to eat water, Lake Neos has given the residents of the neighborhood many benefits, and various rich products can also help them get rid of hunger. The only problem with is that water columns often gush out of the lake.
In addition, small animals drinking water by the lake sometimes die, and people working between lakes sometimes have accidents. However, these are small problems for the local people. The current situation has already satisfied them. Lake Neos has helped them a lot. They can accept some surprises, as long as they can live a life.
Until 1, August 21, 1986 , the people around Lake Neos finished their day's work and gradually began to fall asleep. The village was peaceful and quiet. It was raining in the sky at this time, and a landslide occurred on a hillside next to Lake Neos. Many stones fell into the lake, causing the lake to shake, and a large number of water columns suddenly burst out from the lake surface.
Then an unusually dull scent floated from the lake, spreading towards the surrounding area under the blessing of wind, constantly harvesting life. The villagers who were still sleeping did not realize what was going on, but lost consciousness in their sleep and died silently. Only a few lucky people escaped the disaster and barely saved their lives.
The next day, the government outside sent staff to check and found that more than 1,700 people in the surrounding villages had lost their lives, and the bodies of poultry and various animals were everywhere, and the whole world looked like a doomsday scene. Inside the village, both adults and children have ferocious faces and pale faces, as if they had suffered inhuman torture during their lifetime, and the scene was very tragic.
The center of the disaster is obviously Lake Neos . As the rescuers got closer and closer to the center of the lake, the scene they saw became more and more tragic, like walking in hell. The pungent smell that the people smelled before became even stronger. It was this smell that killed so many people and animals, and a large amount of mud was exposed by the lake. The dead fish were rumbling on their belly, and the scene was in a mess.
This was caused by the big explosion. The gas in Lake Neos was stimulated by a large amount of rockfall, and then a strong air wave burst out, sweeping across the surrounding villages and causing a large number of casualties. Moreover, the lake water gradually shifts towards blood-red over time, which looks very strange, obviously the source, and there must be something hidden in the lake water.
Different guesses
Before entering the disaster area, there were conspirators who were speculating whether Lake Neos was attacked by bombs from a certain country, and then the bursting air waves killed the surrounding residents. But after actually entering this land, all kinds of special scenes declared the failure of this speculation. There were no bullet holes in the corpses of humans and animals. It was definitely not the bomb that caused such a scene.
As for the speculation that human poison gas is used, it is not reliable, because there is no poison gas that can spread for such a long time, causing thousands of deaths in an instant. What's more, the pungent smell that the rescue team smelled was not like weapons such as poison gas bombs, but like the smell of rotten eggs emitted by sulfides. Although it is also poisonous, it is not within the business scope of poison gas bombs and is also excluded.
Then eliminate all possibilities, the fact that in front of you is that Lake Neos in front of you has caused such great damage. This is a natural disaster of . So naturally, the smell of rotten eggs that I smelled before was put on the list of suspicions. Did there be a large amount of sulfide hidden under Lake Neos, which burst out poisonous gas under the impact of the stones, killing a large number of villagers?
However, the sulfide dissipates very quickly with the wind and does not have that much lethality. The researchers also found an abnormality after the autopsy. The villagers did not die of sulfide poisoning. In fact, the concentration of carbon dioxide in the surrounding areas of Lake Neos seriously exceeds the standard. This harmful gas can also kill people after reaching a certain dose.
By looking up geological data, scientists found that Lake Neos was caused by crust changes. It was previously an extinct volcano , but it became the current lake under the gathering of rainwater. Although the volcano is dead, there are still a large amount of magma buried underground, bringing a large amount of carbon dioxide accumulated in the lake water, resulting in a high carbon dioxide concentration.
At the beginning of the disaster, Lake Neos produced a sound of gas explosion and a large number of water columns were churned out, which was caused by carbon dioxide. At the same time, due to the particularity of crater lake , in addition to carbon dioxide, some other toxic gases are also preserved between the various layers of the lake according to their chemical properties, maintaining a dynamic balance, waiting for the right time to erupt.
This opportunity is the stones that fell that day. A large number of stones hit the water surface, destroying the gas balance, and then an explosion occurred. The power of the gas bomb is very terrifying. The toxic gas carried in it continues to sweep across the coast, causing a large number of casualties. The majestic air waves destroy everything, blasting a large pit into the lake, and the trees, flowers and plants were destroyed.
As for the lake water seen by the rescuers, there is also a scientific explanation. researchers detected iron elements in the lake water. Under the calm surface of the lake for hundreds of years, a large number of siderite were manufactured through chemical reactions. This reddish-brown iron ore was also affected by the big explosion, revealing the reddish-brown color, which formed a strange color.
The smell of rotten eggs smelled by the rescuers is also easy to explain. This is because the vulcanized gas produced by volcanoes erupts with a large amount of carbon dioxide and spreads widely in the air, which makes many people mistakenly believe that it is vulcanized gas. After draining the lake water, the "real murderer" of the Lake Neos murder case appeared completely, and the process of this amazing case was also clearly presented to us.
Subsequent processing of
Lake Neos tragedy is not an isolated case. A similar incident occurred in "Lake Morrowin" , not far from this lake, but the scale and casualties are small, and the personnel losses are not serious, so it did not attract special attention from the authorities. However, when the inspectors investigated nearby, they also found that the carbon dioxide content exceeded the standard, and the causes of the accidents in the two lakes were almost the same.
"Lake Morrowin" is also an extinct volcano, and a large amount of carbon dioxide is formed under a long period of chemical cooperation. The stratification of the lake water also exists... It can also take away human life in dullness. This series of special coincidences are amazing. Therefore, if the two accidents are linked together, we can easily deduce the conclusion and obtain shocking new news.
The cause of the accident has been investigated clearly, so the next step is how to finish it. After the scientific researchers made precise measurements, they decided to use relevant instruments to eliminate the carbon dioxide concentration. The specific implementation method is to insert two exhaust pipes several hundred meters long into the lake water, connect the generator here, and then exhaust gases continuously every day to minimize the carbon dioxide concentration in the lake water.
Such a cost is relatively small, and the corresponding effect is relatively average. It can only be a long-lasting measure and cannot cure the root cause. The most direct way is to change the geological conditions of Lake Neos, destroy the volcano at the bottom of the lake, and then completely eradicate the danger. However, this method requires huge amounts of money, and the Cameroonian government does not have enough financial support, so it can only choose a compromise solution.
So a further solution was proposed by scientific researchers. You can use the siphon device to evacuate the water and gas from the bottom of the lake, and use this large device to obtain a short gas evacuation to delay the rate of carbon dioxide accumulation. The siphon device is not cheap, and the Cameroonian government cannot afford to take too much, so this method has certain limitations.
As for the residents who survived the disaster, they were frightened by the huge lethality caused by Lake Neos and dared not continue to live in their original place. Although the government has repeatedly promised that Lake Neos is safe and that similar situations will not happen again in the future, no one is willing to continue to survive by the lake, and this once famous tourist attraction has become a barren land.
After the human retreat, Lake Neos restored its natural landscape, and plants and animals quickly occupied the original space for human survival and became the owner here again. Today, Lake Neos has become more beautiful than before, and there is no way to tell what he has killed thousands of people at all. This "killing lake" has returned to peace, leaving only endless legends to the world.
Of course, no matter how attractive the legend is, tourists are unwilling to risk their lives to go to this area where major accidents have occurred. The only thing that remains at is the two water pipes that are hundreds of meters long, which are still silently emitting carbon dioxide to minimize possible losses.
The government-designed siphon device did not work for too long and was soon evacuated due to excessive burning of money. Lake Neos has become a life-forbidden zone for , hindering human exploration.
Strange natural landscape
Lake Neos is called "killer lake" . It is famous in the world and belongs to an existence that can only be viewed from a distance. In fact, there are many similar mysterious lakes in the world. They are also extremely terrifying and belong to wonders, including attracting places, and even very distinctive landscapes.
For example, Natro Lake is also located in Africa. In the north of Tanzania , it is a huge saltwater lake. It is very terrifying just from the color, like snake scales piled up together, or a strange red color, which is even more exciting to the human senses. It is called "Medusa's Eyes", attracting people's attention and making people unable to help but explore the real reason for its formation.
. The reason why it has such a special color is mainly because the mineral concentration in the water is very high, and it has siderite like Lake Neos, but there are other types of minerals, which accelerate the chemical cooperation process under the stimulation of high heat water temperature, so the color begins to spread to the entire lake, and the bright red that people see appear.
At the same time, there are a large number of red storks living in Natrolong Lake, and the birds singing every day here are a wonder. There are also considerable number of animal bones in the mysterious lake. These are all small animals that have fallen into the lake water. They have undergone calcification reactions under the action of strong alkaline substances in the water, and the remains are preserved intact. After thousands of years, they have not been damaged. Only then can they be fully presented to the public.
In addition to Africa, there are many magical places preserved on this magical continent of Australia, and Sheer Lake is one of them. is the only pink lake in the world, covering an area of about 15 hectares, which is very shocking from the aerial view. This lake was discovered by British navigators in 1802, and has begun to be widely paid attention to it since modern times and has attracted countless attention.
The lake water is shallow, along the coast is a circle of white salt grains, and on the outside is a dense green forest, and on the outside is a narrow white sand belt, which isolates the lake from the ocean and forms a unique attraction. The pink formation of Sheer Lake is mainly related to the algae in the lake. These algae produce carotene , which makes the lake water salinity increase and show a bright pink color.
In addition, more famous lakes include Dead Sea , Boiling Lake , asphalt lake, Salt Marsh , etc. These lakes are all formed due to special geographical conditions and are unique. Among them, the Dead Sea is because the lake surface is low and the salt content is high, which causes almost no animals and plants to survive in the lake water and surrounding areas. This is also the reason why it is called the "Dead Sea".
Humans can float on the Dead Sea without fear of sinking. This is because the density of the Dead Sea water exceeds the density of the human body. Those with low density will naturally float on it, and people will also appear strange things that they will not sink here. These special lakes, like Lake Neos, are all wonders of the world. This magical craft of nature is shocking!
