The Japanese Meteorological Department issued information to advise citizens not to get close to the crater. The lava from the erupting volcano will slide down and pose a threat to human life. Run as far as you can to save your life.

I can’t hold it in any longer, the Japanese volcano is still erupting!

html On June 27th, the Sakurajima volcano located in Kyushu, Japan, finally couldn't hold it in anymore. The volcanic ash filled the sky, causing humans and animals to be indistinguishable from five meters away in nearby cities. The black smoke rose up to 3,400 meters, which was simply despairing. The Japanese Meteorological Department issued information to advise citizens not to get close to the crater. The lava from the erupting volcano will slide down and pose a threat to human life. Run as far as you can to save your life.

In fact, at this time, everyone's attention is more on Mount Fuji in Japan, because various signs indicate that Mount Fuji, which has been dormant for more than 300 years, is suddenly extremely active. Not only has the number of craters increased, but also the internal magma activity has also increased. intensified. As we all know, Japan is an island country located at the junction of the Eurasian and Pacific plates. The land is narrow and broken, and geological activities are frequent.

According to incomplete statistics, about 4 earthquakes occur every day in Japan, and earthquakes usually trigger landslides, mudslides, etc. The internal causes of volcanic eruptions are roughly the same as the causes of earthquakes. There are more than 270 volcanoes of various sizes in Japan, accounting for about 10% of the global total. Among them, there are about 110 active volcanoes, accounting for about 10% of the global total. Although the remaining volcanoes, one-third of the total, are currently dormant, they may be resurrected and have always attracted much attention.

What would happen if volcanoes in Japan erupted at the same time?

There are 270 volcanoes in Japan, which are distributed in a long and narrow land. The densely distributed areas of volcanoes are Honshu Island , Hokkaido , Kyushu Island, and some large islands. If these volcanoes erupt at the same time, we will see the following scene: First, the magma ejected by the volcano will cool down and fly out, sweeping the surrounding cities at flying speed. The objects directly hit by it will be destroyed no matter what they are. Destroyed instantly.

Secondly, there are also larger debris that will fall near the crater. Fine particles and volcanic ash will be carried into the blue sky with the updrafts, and carried to all parts of the world with the movement of the atmosphere, weakening the sunlight. Affects photosynthesis and rainfall and temperature.

Third, there is a terrible thing called lava flow. In short, liquid lava flows on the ground. Its flow speed is about ten kilometers per hour, but the temperature can reach 900°C to 1200°C. Wherever it goes, everything will be destroyed, so it is a quite terrifying existence for nearby residents.

Fourth, the west coast of the United States will be severely affected, because Japan is in the westerly belt , and the wind will bring volcanic ash to the west. Some friends are worried that our neighbors may also be deeply affected, but in fact, for For my country, the possible impact is relatively small.
