The eruption of the 1.15 Tonga submarine volcano has aroused global attention, and indeed, this eruption is really too strong! As can be seen from the wind and cloud satellite cloud map, when the Tonga volcano erupted, the phenomenon of "mushroom clouds" rising on the entire sea surface appeared, and volcanic ash, gas, and water vapor entered the sky to form a huge cloud, which erupted to a height of 20 kilometers. Later, Japan, the United States, New Zealand and other countries have issued tsunami warnings.
According to expert Neibel, the magma beneath the volcano is an ongoing process that still has the potential to erupt in the future. Indeed, judging from the eruption of this volcano, it is an active volcano, and it is not surprising if there is another eruption. However, whether there will be a stronger eruption is uncertain for the time being.
It's just that from the conventional theory, it is unlikely that there will be a stronger eruption. Because this Tonga eruption may be the world's largest submarine volcanic eruption in 30 years, or it may be the largest since the eruption of Mount Pinatubo in the Philippines in 1991.
After the eruption, everyone's concern about the climate problem came, that is, whether there would be a "summerless year" and the cooling of the earth. Indeed, we have all stated a "hard evidence" before about the cooling caused by volcanic eruptions.
That was in 1991, when The Pinatobo volcano in Luzon, philippines, erupted, producing 20 million tons of sulfur dioxide to escape into the atmosphere, preventing some of the thermal energy irradiated by the sun from entering the atmosphere. As a result, in the face of the ash retreat, the surface temperature dropped by an average of 0.5 degrees Celsius, resulting in a cooling situation.
So, after this eruption, a lot of people are talking about whether the earth will cool down, and here we can only say. Indeed, the Tonga volcano, after its eruption, will bring an atmospheric response. However, whether there will be a cooling of the earth, it is not visible at this time.
Because the changes in this active volcano still exist, even if there is the strongest eruption, whether there are 20 million tons of sulfur dioxide and other pollutants, whether it enters the top atmosphere, this has not yet been studied. So, whether it will cause the earth to cool down, this is uncertain.
However, after the eruption of The Tonga Volcano, the world's people were worried about Mount Fuji in Japan and the Yellowstone supervolcano in the United States. Because these two volcanoes are also sleeping volcanoes, once there is a "super eruption", it is indeed possible to bring about great changes in the climate, the cooling of the earth may really appear, these two volcanoes can be said to be the "giant volcanoes" on the earth, and even some studies have pointed out that once the supervolcano erupts, it may lead to great changes in the earth's climate.
Next, we will look at the problem of Mt. Fuji in Japan, and the Yellowstone Supervolcano will not be mentioned for the time being. After the violent eruption of the Tonga volcano, the Japanese people expressed concern that Mt. Fuji was about to erupt. "The number of spitfire mouths in Mount Fuji, Japan has increased by nearly 6 times" has directly attracted everyone's attention. What the hell is going on here? Is it really a fear of eruption?
As we all know, Mt. Fuji in Japan can be said to be the "lifeblood" of Japan's great changes. It just so happens that Mt. Fuji has a special feature, that is, it is located in the "triple point" of plate movement, namely the Amur Plate, the Okhotsk Plate and the Philippine Sea Plate, and it is also located at the junction of the Tohoku Island Arc, the Southwest Island Arc and the Izu-Ogasawara Arc in Japan, which is a highly active area of the "subduction zone".
In the formation process of Mt. Fuji activity, geological activity from the Tension between the Pacific Plate, the Philippine Sea Plate and the surrounding area of Mt. Fuji intensified.
It then causes the basalt to erupt repeatedly through cracks, forming the Mt. Fuji mass. However, the volcano is so unstable that Mount Fuji has erupted 17 times since the 8th century, most recently in 1707. After that, the volcano is in a dormant state, there have been no major eruptions, only small eruptions.
Therefore, many people once suspected that this volcano was "storing energy". After the eruption of the Tonga volcano, the news of the eruption of Mt. Fuji in Japan came.
Korean media reported that in recent investigations, the number of fire vents in Mount Fuji in Japan has increased by nearly 6 times, that is to say, the energy of Mt. Fuji in Japan is increasing "on a large scale", and the magma of this mountain's accumulated power is active and is "expanding" on a large scale, otherwise the fire vents will not increase so much.
And in December 2021, a magnitude 4.9 earthquake struck near Mount Fuji in Japan, raising fears of a volcanic eruption. No, coupled with the eruption of the Tonga volcano, the Japanese people may be even more panicked.
Is it really going to erupt? Indeed, these phenomena indicate that Mount Fuji in Japan is in an enhanced state, coupled with the fact that it is a sleeping active volcano and has been silent for 300 years, there is indeed a possibility of an eruption. According to Toshiji Fujii, director of the Fujisan Institute of Science in Yamanashi Prefecture, Japan, it is not surprising whenever it erupts. Therefore, experts also believe that this volcano may erupt at any time. That really erupted, and the impact was certainly not low.
South Korean media said that if Mt. Fuji erupts, at least 2 hours, lava can flood the village 10 kilometers away. So, on this scale, it is indeed a "nightmare" for Japan. A professor at Aoyama Gakuin University in Japan also said that when Mt. Fuji erupted 300 years ago, the ash reached the sky over Tokyo two hours later.
Japan's metropolitan area, with a population of up to 40 million, would cause astronomically large losses if the eruption caused power and transportation disruptions. Therefore, although Mt. Fuji is a sleeping active volcano, Japan certainly does not expect an eruption, and if there is an eruption, it will inevitably be a disaster. At that time, the atmospheric response may change dramatically.
