Chapter 876 861. The Volcano Is Brewing (25)
After digging out the soil layer, Wang Bo reached out to touch it.
It stands to reason that if the temperature of the sand is caused by sunlight exposure, then the temperature of the soil layer exposed by digging the sand should be relatively low, because the sunlight cannot penetrate the sand layer.
But now when he touches it with his hand, it feels warm, even a little hot.
Seeing this, he continued to dig, and dug out a small pit of about forty centimeters in a few strokes.
At this time, turbid water came out, which is easy to understand. It is next to Hawea Lake, and the surrounding groundwater is rich. It is not uncommon to dig a hole and a spring emerges.
But the water was still warm. Wang Bo dug again in another place, and the water that came out was still hot.
Seeing this, he guessed: "My God, is there really a volcano below here? A hot spring? Then damn it, this is not a surprise, it's frightening!"
New Zealand sits on the "Pacific Ring of Fire" fault zone, where the Pacific plate has subducted after it collided with the Indian and Australian continental plates, an area called the mantle hypercompression zone.
This submersion process provides sufficient energy for volcanic activity. Therefore, New Zealand has the characteristics of high-density active volcanoes and frequent eruptions of volcanoes.
However, the South Island does not need to worry about this aspect. New Zealand's active volcanoes are distributed in the North Island of New Zealand.
There is a triangular-shaped Taupo volcanic area. During the end of the Pliocene and Pleistocene, there were almost all regional surface cracks and volcanic eruptions in the area, such as Ruapehu, Anjou Houyi, Tonggeri Wata, Tarawera and White Island.
The deeper the digging, the hotter the water that came out. Wang Bo really became worried, and said distressedly: "If there is really a volcano down here, my God, then Sunset Town will be destroyed!"
The most significant effect of volcanic activity on landforms is violent eruptions, as is the case with all volcanoes on Earth.
A geologist once said that the North Island of New Zealand was conceived by volcanoes, but it must be known that volcanic eruptions will not only create mountains and hills, but also destroy everything.
Like the famous Lake Rotorua in New Zealand, it is located in a collapsed ancient crater, which is the result of a strong volcanic eruption destroying a hill.
There is also the largest volcanic lake in the world, Lake Taupo, a tourist resort in New Zealand, which was formed by a huge volcanic eruption 20,000 years ago. For the past 2,000 years, thousands of square kilometers of the central North Island have been covered with Taupo volcanic ash.
Bowen was very optimistic, and said: "How can there be a volcanic eruption so easily? I have traveled south and north, and I have lived for so many years, but I have never seen 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 erupts, it may not eject magma. It may be volcanic fountains, volcanic mud ponds, and geothermal steam like my hometown."
Hearing his hand, Wang Bo looked at him and asked, "Are you from Rotorua in the North Island?"
The young man nodded and smiled, "Yes, that's my hometown, the hometown of volcanoes."
Wang Bo thought to himself, no wonder this guy is so calm. It turns out that he has been living on a volcano.
Rotorua is surrounded by small volcanoes, but there have been no catastrophic eruptions in modern times. Volcanoes mainly show themselves through volcanic fountains, volcanic mud pools and geothermal steam.
Volcanic fountains are intermittently spraying boiling water from deep underground into the air, and the height of the water column changes with the ground pressure.
The volcanic mud pond is like a pot of boiling gruel, full of bubbles.
After the bubbles burst, wisps of geothermal steam emerge, which forms geothermal steam, which will escape into the atmosphere continuously through various underground cracks.
In fact, the attitudes of Bowen and the young people are not purely optimistic, and Wang Bo's panic is not because he is too pessimistic. This is the result of different education.
The Chinese geography class talked about volcanoes, focusing on the disasters after volcanic eruptions, and because New Zealand is a country of volcanoes, there are many volcanoes in the country, and they are more familiar with the calm side of volcanoes. What students learn is also about volcanoes. Basically, it will not explode.
Just like earthquakes, Chinese people turn pale when they talk about earthquakes, while New Zealanders talk about earthquakes like talking about a flu, paying attention but not being afraid.
There is no right or wrong in the two attitudes, and neither is better or worse. It is just that the understanding of these natural disasters is different after different education.
To give another example, when it comes to storms, the Chinese shrug their shoulders and let it go. Every year, big coastal cities are hit by hurricanes and storms. After damage to 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 will be responsible for themselves and the losses will be huge.
And the volcanic activity has brought many opportunities to 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 geysers has attracted thousands of tourists every year, and Auckland is a city built on volcanoes.
In addition, New Zealand's volcanic activities have brought various useful minerals and products to the country of New Zealand, for example, volcanic rocks can be widely used as building materials.
Also, the geothermal waters in volcanic hot springs and mud ponds contain various chemical components, making them rare spas.
Underground hot water brought by geothermal activities can also be used to treat rheumatism and muscle disorders, as well as eczema and other intractable diseases. Certain other ailments can be cured to some extent in geothermal pools of varying water temperature and chemical composition.
Volcanic mud and sulfur, a chemical substance rich in hot springs, have a strong bactericidal effect and can be used to treat skin diseases.
Geothermal steam can be collected through pipes and used to heat homes and greenhouses, to heat swimming pools, and in industry to dry and shape wood.
Even geothermal steam can be used for geothermal power generation. New Zealand has achieved great results in the use of geothermal power generation, and its technology has been exported to countries such as South America, Indonesia and the Philippines.
That's what Bowen thought of: "Boss, if you're particularly afraid of a volcano in the ground, develop a geothermal steam power station."
Geothermal steam power generation relies on obtaining steam from the ground. This process will reduce the pressure of underground heat sources and make geothermal energy lose its destructive power.
This point cannot be decided now. Wang Bo intends to ask the geological department to come over and have a look. If there is really a volcano brewing underground, then he will find a way to solve it.
It was painful enough to say it, he thought that the heart of the lakeside really brought him some kind of surprise, but the result surprised him, and there were not many joyful things.
On the contrary, the young men and women and Bowen think that the geothermal heat on the lakeside is very cool, especially because the lakeside is full of water, digging a hole is equivalent to a hot spring, and when the hot water settles and becomes clear, you can go down and enjoy it .
