Angry Killer Lake

The Night of Slaughter Without an Invisible Murderer

  One night in 1986, villagers near Lake Nios in northwestern Cameroon, Africa lived as usual, and no one noticed that strange things were happening in the lake. A 120-meter-high jet of water spewed out of the lake, while a cloud-like cloud rose from the water’s surface and shrouded nearby villages. Someone heard the violent sound of bubbles coming from the lake, followed the sound and ran out of the house to check, but lost consciousness on the way. As the clouds slowly spread, more and more villagers lost consciousness, and even animals were not spared.
  Two days later, the clouds cleared, and some people were lucky enough to wake up, only to find that their family members, neighbors and livestock were dead, and the bodies were lying on the ground, but no one witnessed the murderer. According to statistics, more than 1,700 people died in the disaster, and more animals died.
The murderer is in the lake

  Many survivors blamed the tribal curse for the disaster, but geologists have found through research that the killer of the Lake Nios incident came from the lake. That night, high concentrations of carbon dioxide and toxic gases erupted from the lake, mixing air and water vapor to create that strange cloud. People and animals shrouded in clouds are like being trapped in a giant can of Coke, and the constant emission of carbon dioxide causes them to gradually die of lack of oxygen.
  The reason why so much carbon dioxide erupted is because Lake Nios is located on a volcano, and the magma formed a large amount of carbon dioxide and other gases at the bottom of the lake, and these gases were dissolved in the water; coupled with the hot sunlight all year round, the surface temperature of the lake water is higher than that of the lake bottom. High, which is not conducive to the release of gas. When the gas accumulates to a certain level, coupled with the trigger of landslides and other factors, the lake water will burst into a large amount of gas like a violently shaken cola.
  Lake Nyos is listed as the deadliest lake in the world due to homicides, but it’s not the only lake that kills people.
Lake Kivu with ‘giant bomb’

  There is a Lake Kivu in central Africa, which is more than 1,000 times the size of Lake Nios. It is located on a volcano like Lake Nios and Lake Monaun. The lake also dissolves a huge amount of carbon dioxide and other gases. Also contains explosive methane gas. Geologists have found that Lake Kivu is likely to have a major eruption every 1,000 years on average. Once it erupts, it will not only release carbon dioxide, but may also cause a methane explosion, threatening the lives of 2 million people around. It is also known as the three “killing lakes” in Africa along with Lake Nios and Lake Monaun.

“Bioweapon” Lake Monaun

  As early as one morning in 1984, a man was riding his bike to his farm near Lake Monaun in western Cameroon when he found dead bodies on the road—37 dead in all. Because the disaster happened so suddenly, people even thought that the deceased was attacked by terrorists’ biological and chemical weapons. It was not until the cause of the Lake Nios incident was identified that people suddenly remembered that the death of the deceased in the Lake Monaun incident was very similar to the Lake Nios incident. After further investigation, it was determined that the cause of the Lake Monaun incident was Also carbon dioxide bursts in the lake.
Degas the lake with a “straw”

  In order to prevent the “killing lake” from causing another tragedy, the local government installed special exhaust pipes in Lake Nios and Lake Monaun, just like inserting straws in sealed Coke cans to discharge carbon dioxide, so as to curb Gas buildup on the bottom of the lake. At present, the carbon dioxide gas of the two lakes has been almost eliminated, and the gas content of the lake water will also be continuously monitored to prevent them from threatening the surrounding residents.
  For the larger Lake Kivu, the cost of installing exhaust pipes is much higher, and the local government has not launched any plans to extract carbon dioxide. However, the abundant methane in Lake Kivu can be used as energy export, so the government has built a methane extraction platform, which has brought a certain wealth to the local area. When extracting methane, some carbon dioxide will be released. However, the danger of Lake Kivu has not been eliminated. .
