In the past two days, the "Tonga volcanic eruption incident" can be described as a brush explosion of the whole network, which has aroused the great attention of the international community.
After the eruption, countries around the world issued tsunami warnings one after another and asked people not to go to the sea to avoid unnecessary casualties. Judging from the effective data released at present, the volcanic eruption in Tonga has reached level 5 or more. Simply put, the energy released by this volcanic eruption is equivalent to an earthquake of about 9 magnitude.
The image above is a satellite image of the volcanic eruption, the resulting volcanic ash shot straight into the sky, forming a huge mushroom cloud. From a distance, it bears some resemblance to the scene of the atomic bombing, with volcano researchers saying the tonga eruption released the equivalent of 1,000 atomic bombs in Tonga. While only three deaths have been reported so far (unconfirmed), the impact of the Tonga eruption on the globe is much more than that.
First of all, in addition to magma, the most direct volcanic eruption is to trigger a tsunami, and this Tonga volcanic eruption is no exception. After the eruption, fiji and Samoa around Tonga were greatly affected.
It also displaced people living in lower places, in addition to New Zealand, Japan, and Hawaii in the United States were affected by the tsunami, and even many ships were damaged. Because China has some outlying islands as a barrier, when the tsunami reaches the coastal area, only about 15 centimeters are left, which has no direct impact on China.
As time went on, the tsunami slowly disappeared, and the affected countries also canceled the tsunami warning, but the impact of the Tonga volcanic eruption on human beings is not over, but has just begun.
The aftermath of volcanic eruptions
In fact, the most terrifying thing about volcanic eruptions is not hot magma, but high temperature volcanic ash. The eruption of the Tonga volcano above is not ordinary smoke, but extremely harmful volcanic ash. At 12:00 on January 15, an hour after the eruption, the entire country of Tonga was lost, all Internet facilities were interrupted, and the culprit was the hot volcanic ash!
The ash moves very fast, under normal circumstances, there is no problem in spreading 100 kilometers an hour, and the temperature of the ash is as high as three or four hundred degrees, and the destructive force is very large.
Moreover, there are often some toxic gases in the volcanic ash, which may cause irreversible damage to the respiratory tract if inadvertently inhaled. In addition, there is a certain amount of "sulfur-containing substances" in the volcanic ash, and these sulfur-containing substances react with the water in the air to form the so-called acid rain. After acid rain falls underground, it will not only affect the local vegetation, but even affect the local buildings, but the most important thing is the local water source.
Because Tonga itself is an island nation, freshwater resources are very precious, and now the volcanic eruption has polluted the water source, making the normal diet of the locals a problem.
The global aftermath of volcanic eruptions
Relevant data show that after the eruption of the Tonga volcano, the ash rose at an altitude of at least 25 kilometers, and instantly crossed the troposphere into the stratosphere. If this ash remains in the stratosphere for a long time, it will spread around and affect the rest of the world. According to reliable sources, the current stratospheric volcanic ash has drifted to Australia and may affect more countries in the world in the future.
Because volcanic ash is highly reflective, simply put, volcanic ash is like a parasol, which prevents sunlight from entering the ground, causing the ground temperature to drop.
In addition, it will also affect the vegetation on the ground and perform normal photosynthesis. Historically, every time a large-scale volcanic eruption occurred, the output value of crops in that year or even years would be seriously reduced, resulting in a great famine and the phenomenon of selling children and daughters.
Will the eruption of the Tonga volcano have a great impact on the rest of the world? At present, everything is still unknown, and the Tonga volcano may erupt in the future, or it may cause a chain reaction due to the eruption of the Tonga volcano, causing other volcanoes to erupt as well. Like Mt. Fuji in Japan, it has been stirring up trouble in recent days.
If it is said that because of the Tonga volcano, the eruption of other volcanoes is triggered, then it is really difficult to say what big problems will arise in the future. Of course, everything is just speculation, and there is no need for everyone to worry too much, after all, this is a matter for all mankind, even if there is really any problem, everyone will find a way to solve it together.
The next step is to give you a popular science about what exactly Tonga is, after all, 90% of people did not know what Tonga was before the eruption of the volcano.
"Tonga Science"
At first, when I saw the news, many friends thought that Tonga was a place in Japan or Australia. But in fact, Tonga is a sovereign state, the full name "Kingdom of Tonga" is located in the western South Pacific Ocean, is an island nation composed of 173 islands. The famous tourist island nation of Fiji is just 650 km west of Tonga.
Because of the beautiful scenery, it has attracted many foreign tourists in recent years, and at the same time, the local government has also vigorously developed tourism. But what is more embarrassing is that in the past two years, the local tourism industry has been impacted into a mess, and now it has encountered a volcanic eruption, which can be described as "house leakage and overnight rain", which is not easy.
In addition, Tonga is a little more special, in 1900 Tonga became a British protectorate, to put it bluntly, Tonga at that time, was a British colony. The country's people lived in dire straits until 1970, when the country became independent.
However, after the country's independence, Tonga became a monarchy, and the power was still concentrated in the hands of the king, although in 2008 the king handed over the power to the Parliament, but the king of Tonga still has a lot of influence. So after the eruption, the media reported that the king had moved to a remote villa in Tonga. #Does The Tonga volcano cause the great eruption of Mt. Fuji in Japan ##汤加火山喷发或致中国夏季雨带偏南 #
