The eruption of Tonga volcano is a natural phenomenon. Tonga volcano is located in the volcanic belt around the Pacific Ocean. The Pacific plate subducted at the trench on the east side of Tonga, and the deep dehydration of the subducted oceanic crust caused the melting of the earth's contents (mantle wedge) and the formation of magma. The dive continues and the melting is accumulating. When the pressure reaches the critical point, volcanic eruption occurs in the upper part of the subduction zone. Because magma contains a lot of gas, it often explodes violently, which is very powerful. Unlike Hawaii, where relatively mild magma overflows.

The location of the volcanic eruption is only about 70 kilometers from Tonga Island. The island itself is the product of volcanic eruption. At the front of the Habai volcano, there are many volcanic remains, forming seamounts or protruding out of the water to form islands. Therefore, volcanoes themselves are very common in this area.

Tonga volcanic eruption is the strongest volcanic eruption in this century.

On June, 2022, 65438+1October 14 Tonga submarine volcano erupted in a small scale, but it erupted violently on June, 65438+1October/0/5, making a huge noise. A large amount of volcanic ash went straight into the stratosphere, forming a huge mushroom cloud, and the tsunami triggered also spread to the entire Pacific coast.

From the pictures sent back by the satellite, we can see that the top of the mushroom cloud formed by this explosion is about 400-500km in diameter and about 19-30km in height, which causes the ejected volcanic ash to cover the whole sky in a short time, and its ionization effect is also the main reason for the total paralysis of Tonga's communication equipment.
