Will Japan really sink in the next 30 years?

Let's look at the altitude of Japan first.

6 1% of the Japanese archipelago is a mountain above 300 meters above sea level, and 18% is a mountain below 300 meters above sea level, which adds up to nearly 80%. There are 2 1 mountain above 3000 meters above sea level, and the highest peak is Mount Fuji at 3776 meters above sea level.

Well, in this case, Japan should not be afraid of sinking, so why is there a legend of Japan sinking?

What makes people feel strange is that it belongs to Japan, and I think my country will sink to the bottom of the sea. Is there any special reason?

In fact, this is not unreasonable, and can be simply summarized as four points:

1, surrounded by Mariana Trench.

As shown above, the eastern side of Japan is surrounded by Mariana Trench. The average depth of Mariana Trench is 8 kilometers, and the deepest point reaches 1000 meters. The data also show that Japan is sliding towards the Mariana Trench at a speed of 1.4m per year, with a distance of 200km. Although statistically speaking, it will take hundreds of thousands of years, but this can not reduce people's fears.

For example, there is an abyss approaching your home. Although it is far from your home at present, you are still very scared.

2. Japan is at the plate boundary.

As we all know, Japan is located at the extinction boundary between the Asia-Europe plate and the Pacific plate, and belongs to the earthquake and tsunami-prone zone. According to statistics, more than 20% of earthquakes with a magnitude of 6 or above occurred in Japan. The earthquake not only made the Japanese feel a sense of crisis, but also really affected the geological environment of the Japanese archipelago.

According to the research conducted by the Japan Institute of Land and Geography, after each major earthquake, the Japanese archipelago will decline to varying degrees. For example, after the 3 1 1 earthquake, there were different degrees of decline in many places in Japan, reaching a maximum of 1.2 meters. It can be seen that although Japan will not sink today, there are frequent earthquakes in Japan. If it sinks frequently in the future, it's hard to say.

3. The Japanese metropolis is not high in altitude.

Japan has a special terrain. Although Japan is mountainous and hilly, most of its population lives in narrow plains. Take Guandong Pingyuan, the largest city in Japan, as an example. It is not only the capital of Japan, but also the densest urban agglomeration in the world, where all kinds of high-tech industries in Japan are concentrated. The altitude of this area is only 40 to 90 meters. If the sea level rises, Japan will lose the most suitable land for survival, even if it will not sink completely.

4. The sense of helplessness in the geographical environment

During World War II, almost all countries in East Asia and Southeast Asia were invaded by Japan. Although countries still have trade with Japan today, if they really want to be hard-core, there are almost none. So in fact, Japan, which is surrounded by the sea, still feels very isolated.
