The camera then pans to the ground, waterfalls, primeval forests, herds of wildlife, steaming hot springs, and more!

"When you see this, you might think that we are going to introduce its beauty, mineral resources and various animals. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info You guessed it wrong, our show is not the animal world, we are a show that explores geography. So what are we going to introduce? That's right, it's the hot spring!", Sheng Chun said mysteriously, pointing to the hot spring on the screen.

"Yellowstone National Park covers an area of about 898317 hectares and is located primarily in Wyo, Sam's Country, with parts in Montana and Idaho. Yellowstone National Park is divided into five areas: the Mammoth Hot Springs area in the northwest is dominated by limestone steps, so it is also called the hot steps area, the northeast is the Roosevelt area, which still retains the Old West landscape, the middle is the canyon area, where you can see the Yellowstone Grand Canyon and waterfalls, the southeast is the Yellowstone Lake area, which is mainly lake and mountain, and the west and southwest are the geyser area, which is full of geysers, hot springs, steam pools, hot pools, mud floors and fumaroles. There is a museum of historical monuments in the park. And this time, we will focus on how so many hot springs came about!", talking about how it came about, Sheng Chun's face became a little serious.

"It has one of the largest forests in the world, with about 90 percent of the country's total forest area and about 10 percent of the water surface in the park. There are more than 10,000 hot springs and more than 300 geysers. It is home to more than 290 waterfalls. The park has Yellowstone Lake, Yellowstone River, canyons, waterfalls and hot springs and other landscapes, it is a prestigious tourist attraction, and there are also a lot of wild animals, more than 2,000 species are known!", said here, the midspring crossed a picture.

"The next thing to talk about is the potential danger of this place, the park is one of the largest volcanic craters in the world! According to scientists, as long as the energy accumulated by this volcano erupts, the whole earth will be covered under volcanic ash for at least two years! What is this concept, if we don't see the sun for a month in the summer, then congratulations, you need to wear a coat to pass this summer. ”

"Damn, such a big volcano can't really erupt, right?", the fat man was taken aback, and looked at the TV without blinking.

Feng Yi smiled and said slowly: "It's not so mysterious, how many years have this been, and it's not the same." Before his words fell, the host's words slapped him in the face.

"Scientists have found that the temperature of the lakes in the craters of Yellowstone has risen to varying degrees, and many lakes are evaporating, and small lakes that have dried up have been discovered. Speaking of which, the host pulled out several pictures, which clearly showed the dead corpses of the creatures in the lake, as well as birds.

"Experts on the dead birds believe that the foraging animals were suffocated by carbon dioxide or poisoned by toxic gases such as hydrogen sulfide. Because in this area, experts have found a large amount of these gases. And this is also considered to be a sign of the imminent resurrection of an extinct volcano. ”

A few people were a little stunned when they heard this, this extinct volcano was resurrected?

"And if this volcano is resurrected and erupts, how powerful will it be? Let's give you an example, look!" At this time, a picture appeared again, a huge volcano erupted, and the volcanic ash spewed out covered the sky, like rolling black clouds from the sky, and the end of the world was nothing more than that!

"This is Krakatoa volcano, located in the Sunda Strait of Indonesia, near the island of Lakata. In 1883, a massive eruption released 21 cubic kilometers of ash, and the eruption could be heard as far away as the island of Mauritius, making it one of the largest volcanic eruptions in human history. The eruption and subsequent tsunami destroyed hundreds of villages and cities and killed more than 30,000 people. Two-thirds of the original Krakatoa volcano disappeared in the eruption, and new volcanic activity created a growing volcanic island since 1927. At this point, the host started playing the picture again.

"Krakatoa has spewed almost 21 cubic kilometres of rock into the air, and a large amount of ash has fallen over an area of 800,000 square kilometres. ”

"There is a large pile of pumice rock near the volcano that is so thick that it makes it difficult for ships to pass. Volcanic ash in the air shrouded the surrounding area in darkness for two and a half days. Tiny clouds of dust drift around the earth several times, causing spectacular reddish-orange sunsets throughout the following year. ”

As a result of the eruption, scientists have documented a drop in global temperatures, and the economic damage is incalculable. Okay, let's go back to the supervolcano in Yellowstone. ”

The fat man and the jade tiger were stunned when they heard this, comparing such a super erupting volcano, could it be that the volcanoes in Yellowstone National Park are more powerful?

"Yellowstone's interior has a complex geological structure, with strong volcanic activity, extensive lava and a crust that remains unstable today. Hot springs and hot springs are abundant throughout the park.

The volcano as a whole is centered on the West Thumb on the west side of Yellowstone Lake, 15 miles east to west, and 50 miles to south and north, forming a huge crater.

Beneath this crater lies a reservoir of magma about 70 kilometers in diameter and 10 kilometers in thickness, and this huge reservoir is only 8 kilometers from the ground and is constantly expanding. ”

After the host finished speaking, he showed a few more photos, which were a 3D cross-sectional view showing the terrifying magma activity under the park.

"In the past 2.1 million years, there have been many earthquakes and volcanic eruptions in the Yellowstone area in geological time, and there have been four large-scale volcanic eruptions, and each time there have been huge volcanic eruptions, especially the penultimate volcanic eruption, and the material erupted from the crater has covered an area of about 9,000 square kilometers here, and the volcanic ash has even covered half the world!"

Hearing this, the fat man who was drinking tea squirted out a sip of tea, and watched dumbfounded as the host on the TV broadcast there in a low tone.

"I said fat, you can't pay attention. Feng Yi was sprayed on his clothes by the fat man and glared at him.

"Hehe, people's volcanoes erupted, and the fat man erupted with his mouth!", Lai Asan said with a smile.

"I'm scared, half the world, can any creatures survive?", the fat man was a little incredulous.

"You just think about half the world, isn't there still half of it!", Feng Yi smiled and pointed to the TV.

"That's right, you said that if there was an earthquake in this place, hey, it would scare people to death just thinking about it!", the fat man felt uneasy at the thought of the scene of that huge volcanic eruption, if the earth was really half covered by volcanic ash, and no one would be allowed to live!
