Why is Japan an earthquake-prone country?

Causes of frequent earthquakes in Japan;

Japan is located at the junction of Asia-Europe plate and Pacific plate, with active crustal movement. The distribution of earthquake-prone areas on the earth is regular, that is, most of them are at the edge of the plate. The Japanese archipelago is located at the intersection of the Eurasian plate and the Pacific plate. Because the Pacific plate is thin and dense, and its position is low, when the Pacific plate moves horizontally to the west, it will cross under the Eurasian plate.

Under the collision and extrusion of the Asia-Europe plate and the Pacific plate, the rock formation at the junction is more convenient. Deformation, fracture and other movements produce volcanic eruptions and earthquakes. These plates are often divided by continents and oceans, and are earthquake-prone areas. The Japanese archipelago is located at the junction of the Pacific plate and the Eurasian plate.

Japan is a highly developed capitalist country and the third largest economy in the world. Its resources are scarce, and it is extremely dependent on imports. The developed manufacturing industry is the main pillar of the national economy. Scientific research, aerospace, manufacturing and education all rank among the top in the world. In addition, the cultural industry dominated by animation and game industry and the developed tourism industry are also important symbols.
