A meteorite with a diameter of 1000 meters will only be encountered once in 44 years, which is equivalent to 1000 sandy yellow nuclear bombs.
A meteorite with a diameter of more than 5 kilometers will only be encountered once in 2000 million years, and its power is equivalent to 5.6 sand yellow nuclear bombs.
It takes 10 million years for a meteorite with a diameter of 1.5 kilometers to appear once. Such a meteorite is called a dinosaur killer, and it is the culprit that caused the extinction of dinosaurs.
The energy generated by the explosion of a meteorite with a diameter of 100 kilometers is about 1700 million sand yellow nuclear bombs.
And 1000 kilometers in diameter.It is equivalent to the largest known asteroid Ceres.
Nelson said quietly:
"Actually, tens of millions of years ago, there was a meteorite impact."
"Sixty-six million years ago, an asteroid with a diameter of about 600 meters hit the earth, forming today's Hicksland crater! The damage caused by this planet at that time was simply unimaginable
elephant! "
"The energy generated by its impact is equivalent to more than 90 trillion tons of sky-ladder explosives! At the same time, this impact event triggered waves, and a giant tsunami as high as 100 meters appeared!"
"Luckily the planet hit a shallower part of the ocean at the time!"
"If it had hit the middle of the ocean at that time, it would have caused waves as high as 5000 meters, and at the same time, hot dust and steam would have formed, and the particles and debris from the impact would have been expelled from the Earth's atmosphere and carried along with the planet. Rotation is re-introduced to Earth, sparking wildfires."
"Afterwards, a huge shock wave would cause earthquakes and volcanic eruptions. Dust and particles would cover the entire planet and block sunlight for years or even decades, causing global temperatures to plummet and severely damage biological and plant habitats. And have a direct impact on the food chain."
"If this is the case, the food chain collapsed under such an earth's climate, our human ancestors apes may become extinct, and human beings may not be born..."
Outrageous, Fran and others were shocked!
Meteorites... so scary.
Te outrageously took a sip of Coke, kept himself calm, and asked, "So, what about the meteorite with a diameter of 500 meters? What harm will it cause?"
Nelson said: "Actually, Dragon Kingdom's early warning measures have indicated all possible disasters!"
"First of all, earthquakes! Earthquakes are possible all over the world, especially in the original earthquake zone. The probability of earthquakes is higher and the damage is greater!"
"The second is the tsunami. Although it is not as good as the tsunami of more than 6000 million years ago, it can reach a height of more than 20 meters, and the coastal areas of Berry Country may be greatly affected!"
"However, countries in the southern hemisphere may not experience tsunamis!"
He asked incredulously, "Why?"
Nelson thought for a moment and said, "Because, to trigger a global tsunami, a large meteorite is required!"
"It's hard to understand, so Mr. President, please imagine a scene. When we throw a stone into a pond full of water,
The energy released by the falling stone breaks the calm of the water and creates small waves, but as the stone sinks deeper, it loses more and more energy. "
"The same is true for meteorites hitting the center of the ocean!"
"The tsunami will only be generated in the area affected by the meteorite, but it will not form a huge global tsunami."
"Of course, this does not mean that the ocean will be safe and sound. The waves it forms can travel tens of kilometers away. Although there will be no tsunamis in the southern hemisphere, there will be storms on the sea surface, and navigating ships may be severely damaged!"
"Wait... I suddenly remembered something!"
Nelson reacted abruptly. He looked at Te outrageously, and asked: "My lord, can I ask the National Weather Service to send someone over? I have a question!!"
Outrageous nod of approval.
Ten minutes later, the chief climatologist of the National Weather Service in the United States arrived.
Nelson shook hands with him, pointed to the 500-meter meteorite on the prediction model, and asked tremblingly, "I want to know, will the meteorite fall affect the global climate?"
The chief climatologist thought for a moment, nodded, and said solemnly: "The meteorite will burn after passing through the atmosphere. It carries a lot of heat and will evaporate a lot of water!"
"In the Siberian Plain, there are the Ob River-Irtysh River and the Yenisei River. The river network in the plain is densely covered. There are more than 2000 large and small rivers, many lakes, and continuous swamps. Its north is the Baron Blue Sea, and Arctic Ocean......"
"The heat of the meteorite may evaporate a large amount of water in the plain... These liquefied gases will stay in the stratosphere for several months, or even a few years, and the climate of the entire blue star will change accordingly!!"
"Damn! Damn!" Nelson's eyes were full of fear.
The climate of Blue Star will change!
Could it be that... this meteorite disaster is also related to what Xu Qiu called "the sun goes out"? !
Are the prophecies about disaster true?
Under the extreme low temperature on the surface of the earth, how should human beings survive!
The chief meteorologist, Te Gege, Fran and others all lowered their heads at the moment, their faces gloomy.
At this moment, they also realized the seriousness of the problem.
The credibility of Xu Qiu's prophecy is getting higher and higher...
click.
The paper cup in Te Li's hand was crushed by him, and Coke and ice cubes overflowed.
The entire aerospace agency is shrouded in an atmosphere of dead silence and fear, and everyone is waiting for the decision of the blond president who does not play cards according to common sense.
After a long time, Te outrageously let go of the paper cup and said, "Issue a national order to the entire Federation, and warn the whole people. Prevent earthquakes, tsunamis and other hazards."
"As for disaster prevention...we'll talk about it after the meteorite falls. If it comes true, we, Berry Country, should start preparing for the disaster." He knocked on the table anxiously.
He was very puzzled, why did he encounter such a mess as soon as he took office.
Originally, he wanted to make the Berry Country great again, but now it seems that whether the Berry Country can survive and continue to exist after eleven months is a problem...
Canton, a small fishing village.
"Folks, folks, we're moving! We received an order from the superior management department, and our village will move to a high mountain close to the inland in three days!" The loudspeaker of the village radio station was constantly ringing.
"Folks, hurry up and pack up your luggage, take all your precious things with you, hurry up and fish these two days, do what you can, and avoid the day of the 21st, and then we will go back to the village!" The panic before the disaster.
"Hahaha, the Dangerous Information Bureau is a god in the sky who can help us predict disasters! I'm afraid of a ball!" The fisherman spoke with a strong accent and said to the TV station who came to interview him.The reporter asked: "Uncle, I see that you are sorting out the equipment for fishing in the sea. Are you... you still want to go fishing?"
The fisherman adjusted his straw hat, grinned cheerfully, and said
"Of course we have to fish! In two days, it will be the day when the emergency department said that the whole people will be evacuated. At that time, everyone will gather together. Good guy, there are so many people, there must be people who want to buy fish!"
"I'll fish a little more now, and then I'll sell the fish to everyone! I'll sell it at the cost price! If Director Xu comes to buy my fish, I'll give it away for free! You can even send a boat!"
The reporter laughed loudly: "Director Xu has a lot of time to manage, coordinating the national disaster warning and the construction of protective measures, but he doesn't have time to eat your fish!"
The uncle waved his hand and said heartily: "It's okay! The dolls of the dungeon construction can also come to me to eat free fish!"
"When the construction of the dungeon started, I wanted to go to the construction site, but in the end, I was told to go back and continue fishing. Fish is also food and supplies for war preparations. Fishermen can't be volunteers!"
"I'm so angry, I can only fish desperately, prepare more salted fish for the country, and change everyone's taste when the time comes!"
The camera is accurate to the small fishing village in Canton again O
Niansao or those who went to the Chengjihua fishing station began to pack their equipment and prepare to go fishing.
And the children and old people in the village are basking in the sun leisurely, without the slightest sense of panic or fear of the coming disaster.
Seeing such a peaceful scene, the reporter's eyes were moistened unconsciously. She looked at the camera and said with empathy:
"I used to be a reporter for the international station. I have reported in war-torn areas, and I have also been to the slums in the country and different cities in various countries."
"Nowadays, countries all over the world are either indifferent to this coming disaster, or are in a hurry. Their people live in fear and helplessness!"
"And our people can still bask in the sun leisurely, transfer in an orderly manner, and work together to fight disasters!"
"It is precisely because we were born in such a country, a country that will not give up any of its people, that we can be so happy!"
"I love Dragon Kingdom!!"
Zhejiang Province, on the coastline.
In the sound of humming and humming, the workers carried cement, buoys, etc., surrounded the entire coastline, and then used cement to build the embankment.
And in the sea water 50 meters away from the beach, there is also a wall of large water pockets.
These water bags are made of a special synthetic material, the upper half is an air bag that floats on the water, and the lower half is filled with water.
The parts floating on the sea water are designed as different slogans.
"Dragon State Dangerous Information Bureau, Disaster Forecasting Bureau!"
"Support national construction and strive to be good young people in the new era!"
And between the water bag walls, there is an anti-tsunami wall pulled up with hole cloth nets, and there are traction rope springs to reduce the buffer force.
The outer layer is a water bag wall and hole cloth net, and the inner layer is a big lift made of cement...
Everyone, get ready for this tsunami!
The leader of the disaster warning department of Zhejiang Province, who was inspecting the seaside, was deeply touched by the scene of the whole people fighting the disaster.
He proudly said to the camera: "Why do I have full confidence in disaster prevention in Zhejiang Province, because I have full confidence in our people!"
The reporter glanced at the barrage in the webcast room and asked, "Leader, all of us netizens have a question. If there is no advance prediction of this crisis situation, can we give early warning before the tsunami comes?"
The leader's face was full of admiration for the emergency situation bureau, and said: "Even with the most advanced tsunami warning system in the world, it can be about half an hour in advance at most."
The reporter asked: "Many parts of the world have not paid attention to this disaster. For those people, what should they do without the help of the state to prevent disasters?"
"First of all, they should condemn their country for not taking measures. Please remember that we are not living in a peaceful age, we are just living in a peaceful country! A country that loves its people!"
"If you want to save yourself, you need the following methods..."
"They can prepare a water first aid kit in the office and at home, preferably an escape first aid kit, which must contain enough drinking water for 72 hours, dry food, first aid medicine, flashlights and warm clothing. After the tsunami, the entire city may be submerged, They've got to last until the search and rescue team arrives!"
"In addition, prepare life jackets, buoys, etc..."
"Of course, the most important thing is to have an earthquake and tsunami evacuation plan. You have to remember that tsunamis are caused by storm surges, volcanic eruptions, underwater landslides and submarine earthquakes, the most important of which are submarine earthquakes.
I”
"And this time the tsunami was caused by the fall of a meteorite, so there must be an earthquake.
"Therefore, in addition to preventing tsunami, they also need to prevent earthquakes! Without state intervention, people voluntarily evacuate, the effect is very poor, and the number of casualties and property losses are estimated to be not small!"
The director of the Zhejiang Provincial Disaster Bureau smiled proudly at the camera:
"As for us? Don't worry about anything, follow the country, and the country will keep you safe!!"
In the webcast room, netizens were excited.
"Thanks to the motherland!"
"I love Dragon Country!"
"Just follow the country and we'll all be fine!"
