The Treasure Hunt of an Antique Dealer

After thinking about it, the famous city of Pompeii is about ten kilometers away from Mount Vesuvius. A big eruption directly buried the city of 20,000 people.

The Nyiragongo volcano is only ten kilometers away from Goma, and it looks bigger than Vesuvius volcano.

At this moment, I admire Naples, Italy, and the city of Goma on the screen. The former has a population of almost one million. Both large cities are staying ten kilometers away from the dangerous active volcano. This place is really chosen. ...

It's not that I simply think that people are big-hearted, and there is no way for more reasons!

What a similar environment, Italy is facing the sea and the mountains, surrounded by fertile land;

The city of Goma is a large fertile land with volcanic ash facing the big lake and backing the mountain.

The same is suitable for human habitation, with mountains, water and fertile soil, and each is also a convenient transportation location within a certain range. Except for the **** volcano next door, it is a good place no matter how you look at it.

From ancient times to the present, there have not been so many choices for human reproduction. As long as you look at a place suitable for one or two generations to live, there will be crowds of people gathering and reproducing.

Now the Italians have set up the world's largest volcano monitoring station on the edge of Mount Vesuvius, and an early warning can be given to the volcano as soon as it changes.

Regardless of how difficult it is for Naples, a city with a population of nearly one million, to move across the city, at least modern technology can basically give the Italians time to warn.

It can only be basically, nothing is absolute. The volcanic eruption is not a typhoon, and no one can guarantee that Vesuvius will explode without notice. The monitoring station will not be given warning time at all, or the time will not be too short at all. Give the city enough time to evacuate.

Italy, a developed country, can equip its large cities with large-scale and technologically advanced testing stations, and volcano research organizations in other countries are also happy to do research there, but what about the city of Goma?

In peacetime, it is good to say that sometimes some organizations that study volcanic activity send people here to conduct research, but since a large number of refugees from Rwanda poured into the city of Goma the year before, the security in this area is extremely bad!

The organizations and experts studying the volcano all ran away, and God knows when it will explode again.

Naples as far away as Italy only needs to worry about the threat of volcanoes. Even if there is strong wind in the Mediterranean Sea to the south, it will not be so big that it will blow the city to the ground.

But Lake Kivu next to the city of Goma is even more terrifying. Once this killing lake erupts on a large scale, it can kill all the creatures around the lake in one night, including at least two million people!

According to Dallaire, this Lake Kivu is in a geologically anomalous area. 300 cubic kilometers of carbon dioxide and 60 cubic kilometers of methane are dissolved in the lake layer, and it also contains very toxic hydrogen sulfide.

These gases may be released explosively in the form of lakes and marshes at any time. Once they erupt, because carbon dioxide, methane, and hydrogen sulfide are heavier than air, they can cover the valleys around Lake Kivu in a very short time, and they cannot be quickly emitted.

There will be methane and carbon dioxide at the bottom of almost all lakes. If it is a swampy area, methane will "bubble" on the water surface, which is not surprising.

But this is too much. It is impossible to produce so much methane relying on the decomposing and decomposition of the plants at the bottom of the lake.

Where did so many harmful gases come from?

A huge amount of dangerous gas comes from magma!

Lake Kivu is on a huge and active volcanic belt. The magma below the lake rises to the surface. During this process, the pressure gradually decreases, and the gas in it is released into the lake water.

Under normal circumstances, the gas in the lake should be slowly released in winter-the upper lake water is cooler in winter and has higher gas solubility, which makes the dissolved gas in the deep lake water move upward spontaneously.

The cold weather dissipates every year, so that nothing happens. The toxic gas accumulated in the deep layer of the lake is absolutely limitless.

But Lake Kivu is near the equator. Although there is no extreme heat throughout the year, the temperature is still quite warm throughout the year, and it may even be slightly muggy for a short time during the rainy season.

The consequence is that the temperature of the upper layer of Lake Kivu is always higher than that of the lower layer: the lake is too deep, the average depth is 220 meters, and the deepest place is nearly 500 meters. The temperature of the lower layer is always cold and bitter!

This is all right, the gas cannot be transferred upwards for many years, and it is "locked" to the bottom of the lake. Once the amount of dissolved gas is close to the upper limit of dissolution...

There is another group of large and active volcanoes on the side. When the volcano has an earth-shattering eruption, and the deep lake is saturated with gas, the entire Lake Kivu will be like a bottle of soda after a shake, and it will be explosive. freed!

Dallaire continued on the side: "Excluding the methane, the 300 cubic kilometers of carbon dioxide dissolved in Lake Kivu is equivalent to the carbon emissions of global fossil fuel burning for more than half a month.

If this carbon dioxide is released explosively...At least two million people will die in a circle of Lake Kivu!

Unless people happen to be on the top of a nearby mountain that is high enough, no one will be spared except for firefighters and divers who can carry oxygen cylinders on their backs.

Gas masks are useless, normal air will be squeezed to high places, the height may rise to hundreds of meters, the lower layer of oxygen is almost zero. "

"That methane wouldn't blow up, right." Zhang Nan still remembered the words of Brother Guan just now.

"This will not explode. The interval between the occurrence of the big explosion that destroys all living things should be longer, and the conditions are more demanding first.

The concentration of methane at the bottom of the lake is now enough, but the level of volcanic eruptions in recent decades has been a little lower.

Many volcano experts believe that there are huge karst pipelines that were blocked at the bottom of Lake Kivu and that once pierced every thousand years or so.

Wait for that to pass, then..."

Dallaire raised both hands: "It's all over!

Another possibility is that the volcanic eruption caused a sufficiently large earthquake, the soda bottle erupted, the release of carbon dioxide and methane was too fast, and it was ignited by the magma before it had time to squeeze out the oxygen.

This is much more reliable than the prediction of some super volcanic eruption in Yellowstone Park. In fact, I am also looking forward to seeing such a grand occasion in this life.

Like Mr. Guan, we are not as cold as iron, but it will happen sooner or later. "

That's right, unavoidable disasters, time issues, I don't know when it will happen.

"Then is there any way to avoid it?" Zhang Nan was a little curious.

When Guan Xingquan heard this, he answered, "Of course there are, or two.

First, erect dozens of hundreds of pipes on the lake, and use a pump to turn it like a water pump. It stirs the water of the lake that is still at a depth of 250 meters and leads to a limited amount of time to stir up the saturated gas.

There is a much smaller lake in Kameron that is similar to Lake Kivu. In 1986, a poisonous gas erupted and killed almost two thousand people. Now someone is doing such an experiment over there.

However, the cost is very high. The lake in Lake Kivu is at least two thousand times the size, the number of vertical pipes is too large, the cost is too high, and the operating cost is not small. Anyway, don't expect the Congo and Rwanda to invest.

The second one is very simple. The two countries organize, remove people, and throw a deep nuclear bomb into the lake, and it will be safe for a thousand years with a single bang. "

"forget it!"

Zhang Nan shook his head inwardly.

There seem to be a few РЮ-2 (8Ф59) nuclear deep bombs in my warehouse, but they are actually stored as ordinary nuclear deterrents.

It can be mounted with Figure-95, 142 and Figure-22M. There are various initiation methods, including air explosion, ground explosion (surface explosion) and underwater explosion.

However, it is not the Soviet Union or the United States during the Cold War period that the number of nuclear bombs is "rich", so it will not use the 10,000-ton level nuclear deep bombs to blow up submarines.

It will not be used in Lake Kivu.

As for the vertical pipe...

Regarding my own bird, the railway will go there in the future, but at least I have never heard of the death of 2 million people in the Great Lakes of Africa in my previous life.

Looks like... In 01 or 02, there was news that the Congo volcano erupted and the Rwandan army ran away.

At the moment when I saw the news, I felt strange: Congo has a natural disaster. What is the Rwandan army running?

Later, it became clear that not only were the two places next to each other, the Rwandan army was also an invader.

Suddenly he slapped his forehead, and Zhang Nan smiled.

Really, I almost forgot. I am a traverser who can still watch for more than 20 years. I was actually bluffed by the guy Guan just now!

The tiger's body shook and looked left and right.

Yes, Xiang Weirong and Guan Xingquan, who know him best, know that there will be trouble~www.readwn.com~ I said guys, I don’t think that Lake Kivu can’t blow up for the time being. "

As he said, he pointed to the big screen, "I have never seen a smoking active volcano in my life, so I have to go and see it.

Thomas, ask Kigali when they will withdraw their troops.

I have given them a lot of face, so don't blame us for not talking about old friendships anymore!"

We all know that once Zhang Nan has such an attitude, the matter cannot be changed, so let's implement it.

As for Xiang Weirong and Guan Xingquan...

Even if you are not afraid of possible dangers, that can only show one thing: there is no danger for a certain period of time, and Anan never goes wrong with this!

This guy is more afraid of death than anyone else!

The Tu-142M3 is about to enter the sky over Lake Kivu, there is no need to continue patrolling, and it can return as planned.

This Thomas just planned to send someone to contact the Rwandan high-level officials. What a coincidence, the news came back from Kigali, the capital of Rwanda.

The group does not have much investment in Rwanda. Except for cassava, banana and mountain silverback gorilla, there are only people who Zhang Nan looks down on!

However, the group still has an industry there. It is still in its capital. It is very famous and has a very good business. Some diplomats, high-level multinational groups, and wealthy tourists who come to Kigali like to live there.

It seems that if you can live there, you can add some justice to yourself.

According to the latest name after more than two decades, it is an Internet celebrity check-in place, which is still international.

That's right, that was the big hotel that was used by Guan Xingquan as the headquarters last year, and now it was renamed "Five Francs".

Zhang Nan doesn't need people to be grateful, Guan Xingquan is even more so. This is to make the whole world remember that his group collected the money at that time.

Collect money to do business, guarantee reputation, only 5 Rwandan francs!
