Vol 2 Chapter 619: Earth farts: lake flip

Natural disasters, also known as natural disasters, natural disasters, famines, etc., refer to anomalies that occur in nature, and such anomalies can cause serious disasters to surrounding creatures and human society.
　　This is what mankind defines natural disasters.
　　Throwing away the explanation of Wen Cree does not say that in fact, since the birth of mankind, it has been fighting various natural disasters and paying enough price.
　　 Winter, snow disasters, will kill people.
　　Summer, drought, will kill people.
　　 Plateau, avalanche, will kill people.
　　 Coastal, tsunami, will kill people.
　　 Usually, typhoons, floods, earthquakes, volcanic eruptions, meteorite impact will still kill people.
　　 Natural disasters often broke out suddenly, making people unpredictable, so they suffered heavy losses. Of course, in the long years, humans have also summed up many experiences, learned to detect natural disasters, and used various methods to prevent it.
　　 For example, in snowy mountains, absolutely no loud noises and strong vibrations are created to prevent avalanches. On large rivers, many dams and reservoirs were built to regulate the amount of river water and prevent flooding. In addition, artificial rainfall is used to alleviate the drought, meteorological satellite warning, evacuation of people to reduce typhoon losses, and so on.
　　 However, under the terrifying power of nature, human power is too small, it can only prevent, avoid and reduce losses. It is really too difficult to resist.
　　Take Typhoon as an example.
　　Typhoon is the most common natural disaster, with frequent occurrences, great power, wide range of impact, and serious losses.
　　 Some people have raised the question of whether typhoons can be eliminated with the level of science and technology on modern earth. For example, a large equivalent of nuclear bomb was detonated in the center of the typhoon, destroying the typhoon, and eventually calming the typhoon.
　　 In fact, it can't.
　　The heat released by an ordinary mature typhoon is basically equivalent to detonating a 10 million equivalent nuclear bomb every 20 minutes. The heat released every hour is thousands of times that of the Hiroshima atomic bomb. If only a few ordinary nuclear bombs were detonated in the center of the typhoon, they would have little effect at all.
　　 One sentence: Nature is the master of the planet, and humans are nothing but parasites on the surface of the earth.
　　 65 million years ago, an asteroid about 11 kilometers in diameter crashed into the Gulf of Mexico, causing the Cretaceous mass extinction. About 75% of the world’s organisms, including dinosaurs, were extinct, and the earth had no effect.
　　The earth has existed for nearly 4.6 billion years, and no accident, it will continue to exist for several billion years.
　　 There are only humans with thousands of years of civilization and millions of years of biological evolution. At least for now, it is really not worth mentioning to the earth.
　　 For the natural disasters of the earth, human beings can only avoid and prevent as much as possible, but cannot resist.
　　 And a headache is that some common natural disasters can be detected in advance because of obvious signs, and there is sufficient time for prevention.
　　For other uncommon natural disasters, no abnormal state can be found before it happens. Once it happens, it will take a lot of life very quickly, which makes people unpredictable and can only help the goddess of luck. This type of natural disaster, a very famous one, is called... Lake flip.
　　 There are very few recorded cases of lake flipping natural disasters, and so far there are only two, but each of them caused a lot of casualties.
　　 The first case, Lake Monauen.
　　 Lake Monauen, located in Cameroon, a country in central and western Africa, suffered a natural disaster on August 15, 1984.
　　 When the natural disaster occurred, there was no sign, and the tremendous tremendous happened, like a death swaying a sickle, taking every life accurately, and then hiding in the darkness.
　　People affected by natural disasters have absolutely no ability to resist, nor can they send messages to the outside world for help, and they all die in a very short period of time. The situation of natural disasters was not observed by people who had nothing to do with them. It was only due to accidental circumstances that they entered the scene after the outbreak of natural disasters.
　　 The first person discovered was called Ahaji Abdul. During his journey, he saw that there were corpses all over the road and the car crashed out of the road, and no one survived.
　　After the incident, a total of 37 people died in this disaster.
　　 This figure is nothing. The most important thing is that the deceased have no signs of struggling. It is like suddenly dying from an acute infectious disease, which caused a huge panic. It took a long time to investigate.
　　 The second case, Lake Nios.
　　 Lake Nios, also in Cameroon, a country in central and western Africa, suffered a natural disaster in the early hours of August 21, 1986, two years after the first case.
　　When the natural disaster occurred, it was in the middle of the night, and it was still located in a densely populated area, so a large number of people in their sleep were taken away collectively without reacting.
　　 An eyewitness who entered the area afterwards described that there was no one in sight, or that he was all dead.
Because they are located outside the area, they are extremely lucky to have recovered a life from the disaster. The description of the experience: I am standing alone in the heap of dead people, all the dead people inside and outside the house, all the cattle, sheep, and dogs are dead, the family 56 , 53 of them lost their breath.
　　Post-mortem statistics show that there were more than 1,700 deaths in this natural disaster, and countless dead animals!
　　 This obviously caused huge panic, especially just two years after the first case.
　　 To this end, scientists from all sides came to conduct rigorous investigations and studies, and concluded that the events of Lake Nios and Lake Monauen were caused by the lake flip.
　　What is a lake flip?
　　 It turns out that Lake Nios and Lake Monauen are not ordinary lakes, and there is a magmatic zone below the lake bottom. The existence of this magmatic zone will allow carbon dioxide to continuously leak into the water and accumulate at the bottom of a slow-moving lake with extremely high water pressure.
　　When carbon dioxide accumulates to the limit, it will erupt, and then hundreds of thousands of tons of carbon dioxide will quickly rush out of the lake and spread to the surroundings.
Because the density of carbon dioxide is 1.5 times that of air, a lot of carbon dioxide is like a thick carpet on the ground. Wherever it goes, almost all the air is driven away. First, a high-concentration carbon dioxide area is created, followed by It takes a long time to create a pure carbon dioxide area.
　　Carbon dioxide, as part of the air, is not harmful at low concentrations, such as 0.04%.
　　But when the concentration rises to 1%, it will make people feel depressed, dizzy, and palpitations.
When 　　 reaches 5%, people will feel wheezing, headache, and dizziness.
When 　　 reaches 10%, the human body's functions will be seriously confused, causing people to lose consciousness, unconsciousness, and stop breathing and die.
　　As for the higher concentration, reaching the level of pure carbon dioxide, let alone humans, as long as plants, animals, and microorganisms that depend on oxygen for aerobic respiration cannot survive.
　　 This is the lake flip!
　　 Someone vividly named this kind of natural disaster, called...the fart of the earth.
　　 Um, the fart of the earth.
　　 The earth put a fart, and then claimed the lives of hundreds of people.
　　 And this is the power of nature's natural disasters.
　　……
　　 Lake Taklima is a lake that periodically undergoes a "lake reversal", which can be determined.
　　However, when Richard first became interested in the Taklimakan Lake, he did not know this. The interest in the Taklimakan Lake is entirely due to the name.
　　After all, not every desert is called Taklamakan. The name of the desert on the earth is actually pressed on a lake in the current world, which makes Richard have to be curious.
　　 After hearing about the legend of the death of Taklimakan Lake from the wizard Teddy, Richard is very eager to explore the secrets of the lake.
　　 had many speculations at the time, and later discovered more in the process of exploring the small village of Yatis. After checking into the lake, I finally determined that the Taklimakan Lake is a lake that will have a "lake flip" natural disaster.
　　 Then everything can be explained.
　　In the legend of Lake Taklamakan, the so-called of death is nothing but hundreds of thousands of tons of carbon dioxide gas accumulated at the bottom of the lake. And every few hundred years, Reaper will wake up from a deep sleep and take away all the life it sees, because every time carbon dioxide erupts to the outside world, it takes a long time to re-accumulate. A period of hundreds of years is an accumulation cycle.
　　Understood this, Richard's heart raised vigilance against the Taklimakan Lake, and warned Nancy and Gro that it was better to stay away from the lake.
　　Although he can see that the amount of carbon dioxide accumulated at the bottom of the lake is not far below the limit and will not erupt to the outside world for decades, many things are not absolute.
　　A small earthquake, or a boulder falling into the water, is enough to break the delicate balance between the carbon dioxide at the bottom of the lake and the lake water, allowing carbon dioxide to be released in advance. At that time, the killing effect and the killing range may be somewhat reduced, but the people in the core area do not have enough precautions, and they are certainly dead.
　　After understanding these things, even if the matter came to an end, with the convening of the exchange meeting, Richard left the Taklamakan Lake aside. After all, his main purpose is the treasure of the Black Spirit King, the ultimate secret of the Black Spirit Empire ~ EbookFREE.me ~ not a geographical adventure.
　　 He just wanted to wait for the exchange meeting and find a way to stay and continue to dig and find the small village of Artis without putting too much energy into a lake, even if this lake is rare and the entire earth has so far proved three.
　　 But who knows, the development of things is unexpected, the exchange meeting is actually a big trap, the dark blue castle collaborated with the mysterious organization, preparing to kill all the wizards attending the meeting.
　　 For such traps, conspiracies and the like, Richard was not very cold, and was not prepared to participate in it. After helping Gro, Nancy and others break through, they were ready to leave.
　　 thought more about one thing: After the trouble of the Deep Blue Castle, the entire East Coast was in chaos, and the surrounding of the Dark Blue Castle became extremely dangerous. If you want to continue to dig and find the small village of Yatis, I am afraid that it is difficult, and you need to find another way.
　　 is like thinking about a way, new questions come. The mysterious organization's black robe wizard didn't know why. He even regarded him as a must-have target, and mobilized a lot of power to round up, so that he could not escape even if he wanted to escape.
　　In a crisis, he remembered the dangerous existence of Lake Taklamakan. Simply fled to Lake Taklamah, taking advantage of the fact that the enemy did not notice anything wrong, and released a lot of carbon dioxide in advance at the bottom of the lake to solve all troubles.
　　 He did not feel anything wrong with this behavior of taking advantage of the situation, nor did he feel invincible.
　　No matter how he says, this way, he does not need to spend any effort to kill people or continue to run away. Now he only needs to receive loot on many corpses.
　　 Well, receive loot.
