Chapter 861: .Volcano is brewing (2/5)

Digging out the soil, Wang Bo reached out to touch it.
It stands to reason that if the temperature of the sand is caused by the sun exposure, the temperature of the soil layer exposed by the excavated sand is relatively low, because the sunlight cannot penetrate the sand layer.
But now he touched it with his hands, feeling warm and even a little hot.
Seeing this, he continued to dig and dig a few pits for a few centimeters.
At this time, turbid water came out. It is easy to understand that there is Lake Hawea next to it. The surrounding groundwater is rich, and it is not uncommon to dig a pit and pop a spring eye.
However, the water was warm, and Wang Bo changed the place and dug again. The water that came out was still hot.
Seeing this, he guessed: "My God, is there really a volcano below? A hot spring? That's not a surprise, it, it's frightening!"
New Zealand is located in the "Pacific Fire Ring" fault zone. This is an area called the mantle heat and pressure zone after the Pacific plate collided with the Indian and Australian continental plates.
This infiltration process provided sufficient energy for volcanic activity. Therefore, New Zealand is characterized by high-density active volcanoes and volcanic eruptions.
However, the South Island does not need to worry about this. New Zealand's active volcanoes are all located in the North Island of New Zealand.
There is a triangle-shaped Taupo volcanic area. Almost all regional surface cracks and volcanic eruptions occurred in the area during the last Pleistocene and Pleistocene, such as Ruapehu, Anruhouyi, Tonge Ri Tile, Tarawera and White Island.
The deeper the digging, the hotter the water came out, Wang Bo was really worried, and said distressed: "If there is a volcano below, my God, then the sunset town will be ruined!"
The most significant effect of volcanic activity on the landform is the violent eruption, as is the case with volcanoes on Earth.
Geologists once said that the North Island of New Zealand was born of volcanoes, but we must know that volcanic eruptions will not only create mountains and hills, but also destroy everything.
Like New Zealand's famous Lake Rotorua, it is located in a collapsed ancient crater, which is the result of a strong volcanic eruption destroying a hill.
There is also the world's largest volcanic lake, New Zealand's tourist resort Lake Taupo, which was formed by a huge volcanic eruption 20,000 years ago. For the past two thousand years, thousands of square kilometers of central North Island have been covered with Taupo ash.
Bowen was very optimistic, saying, "How can a volcanic eruption occur so easily? I have walked south and north, and I have lived for so many years without seeing a volcanic eruption!"
The young man also said, "Yes, even if there is a small volcano below, it may not erupt, and even if it does, it may not erupt lava. It may be a volcanic fountain, volcanic mud pond and geothermal steam like my hometown."
After hearing his hand, Wang Bo looked at him and asked, "Are you from Rotorua on the North Island?"
The young man nodded and smiled, "Yes, that's my hometown, the volcano hometown."
Wang Bo secretly no wonder this guy is so calm, it turns out that people have been living on the volcano.
Rotorua is surrounded by small volcanoes, but there have been no catastrophic eruptions in modern times. Volcanoes mainly express themselves through volcanic fountains, volcanic mud ponds and geothermal steam.
A volcanic fountain sprays boiling water from deep underground intermittently into the air, and the height of the water column varies with the pressure on the ground.
The volcanic mud pond is like a pot of boiling porridge filled with air bubbles.
After the bubble burst, a stream of geothermal steam appeared, which formed geothermal steam. These steam will continuously escape into the atmosphere through various underground gaps.
In fact, the attitude of Bowen and the youth is not purely optimistic, nor is Wang Bo's panic because he is too pessimistic. This is the result of different education.
Chinese geography class talked about volcanoes, and introduced disasters after the volcanic eruption. Because New Zealand is a volcanic country and many volcanoes in the country, it is more familiar with the calm side of volcanoes. Students also learn about volcanoes. It basically does not erupt.
It ’s like an earthquake. Chinese people talk about earthquakes and change color. When talking about earthquakes in New Zealand, it ’s like talking about an epidemic cold. They value but do n’t fear.
There is no one who is right or who is wrong or who is better than the two, but they have different understandings of these natural disasters after different educations.
For another example, when it comes to storms, the Chinese shrugged their shoulders. Every year, large coastal cities are hit by hurricanes and storms. After the damage to the infrastructure, there are countries to carry out post-disaster reconstruction.
New Zealanders have a headache when it comes to storms, because the damage caused by storms can only be settled by insurance companies, otherwise they are responsible for themselves and the losses are great.
And volcanic activity has created many opportunities for the New Zealand economy, especially in the tourism and souvenir industries.
For more than a century, the stunning scenery of New Zealand's volcanoes and volcanic fountains has attracted thousands of tourists every year. Auckland is a city built on volcanoes.
In addition, New Zealand's volcanic activity has brought a variety of useful minerals and products to the country. For example, volcanic rocks can be widely used as building materials.
Also, the underground hot water in volcanic hot springs and mud ponds contains various chemical components, which makes them a rare mineral spa.
The underground hot water brought by geothermal activities can also be used to treat difficult diseases such as rheumatism and muscle disorders, as well as eczema. Some other diseases can be treated in geothermal pools with different water temperatures and chemical compositions.
Volcanic mud and sulfur, a rich chemical substance in hot springs, have a powerful bactericidal effect and can be used to treat skin diseases.
Geothermal steam can be collected through pipes for heating homes and greenhouses, heating swimming pools, and industrially drying and shaping wood.
Even geothermal steam can be used for geothermal power generation. New Zealand has been very effective in using geothermal power. Its technology has been exported to South America, Indonesia, and the Philippines.
Bowen thought of this: "Boss, if you are particularly afraid of a volcano underground, then develop a geothermal steam power station."
Geothermal steam power generation relies on obtaining steam from the ground. In this process, the pressure of the underground heat source will be reduced and the destructive power of the geothermal will be lost.
This cannot be decided now. Wang Bo intends to come to the geological department to take a look. If there is a volcano brewing underground, he must find a solution.
It's so painful to talk about, he thought the lakeside heart really brought him a surprise, but it turned out to surprise him, and there was not much joy.
On the contrary, young men, women, and Bowen felt that it was cool to have geothermal heat on the lakeshore, especially because there was so much water on the lakeshore, digging a pit was equivalent to a hot spring. When the hot water sedimentation became clear, you could enjoy it . (To be continued.)
