How harmful is the eruption of Mount Fuji volcano to China?

Mount Fuji volcanic eruption is harmless to China.

Because the eruption level of Mount Fuji is level 3 all the year round, there is only one eruption reaching level 5, and the probability is very small. Secondly, due to geographical reasons, China will not be affected. Mount Fuji is located in the westerlies, and the airflow flows from west to east, while China is in the west of Japan, so natural volcanic ash will not float over.

This shows that people's worries are unnecessary. Even if Mount Fuji really erupts, it won't have any influence on our country. Only Japan needs to be fully prepared to ensure the safety and property of residents and minimize risks.

Level 3 volcanic eruption is common, but it is dangerous to reach level 4-5. A volcanic eruption of magnitude 4 is equivalent to an earthquake of magnitude 8.2. A volcanic eruption of magnitude 5 is equivalent to an earthquake of magnitude 8.7.

If it can reach magnitude 6, it is equivalent to a magnitude 9.3 earthquake. Not only did the building collapse in an instant, but people also had no time to escape, so they could only be "slaughtered".

Mount Pinatubo in Luzon, Philippines, erupted in 199 1 year, and it was recorded that 20 million tons of sulfur dioxide was ejected at that time.

The emission of sulfur dioxide reduces the sunlight of the earth by 10%, and reduces the global temperature by 0.5 degrees. You can imagine how horrible the scene was.

When the volcanic eruption reaches magnitude 7, which is equivalent to a magnitude 9.8 earthquake, buildings will suddenly become fragments, and a large number of cracks will appear on the ground, which may even lead to floods, mudslides, landslides and avalanches on the top of the mountain.

18 15, the eruption of Tambora volcano in Indonesia was terrible, which not only killed 50,000 people, but also affected the global temperature, with an overall drop of 0.53 degrees.

This is also the birth of the word "year without summer". The eruption of magnitude 7 volcano made there no summer in 18 16. After that, once Tambora volcano is mentioned, people will feel cold behind them and think of the word "a year without summer".

What if it reaches level 8 volcanic eruption? Equivalent to 10.2 earthquake. The Tangshan earthquake and Wenchuan earthquake in China were both magnitude 8, and the scene state was already terrible. I can't imagine what 10.2 would look like.

However, it is unlikely that Mount Fuji will erupt to magnitude 8, but the Yellowstone volcano in the United States is possible, because its crater diameter is so large that it is impossible to observe its specific number.
