“一衣带水”总是被用来形容日本与中国之间的距离,可是两国间的地形地貌差距却可用“天壤之别”来概括。日本列岛正好位于亚欧板块与太平洋板块的交界处,当太平洋板块向西呈水平移动时,它就会俯冲到相邻的亚欧板块之下。两大板块交界处的岩层便出现变形和断裂,从而产生火山爆发。因而不难理解,罕见的活火山在日本居然有83座之多,在世界活火山总量中占到了十分之一,日本四分之一的国土面积竟然是由火山喷发物覆盖着。这些令人惊叹的数字总是鼓动着我的好奇心,想要去看个究竟。
“A strip of water ” is always used to describe the distance between Japan and China, but the difference between the topography of the two countries is available “big difference” to summarize. The Japanese archipelago is located exactly at the junction of the Eurasian Plate and the Pacific Plate, and when the Pacific Plate moves westward, it subducts beneath the adjacent Eurasian plate. Rock formation at the junction of the two plates will be deformed and fractured, resulting in volcanic eruptions. It is therefore not difficult to understand that the rare active volcano has as many as 83 in Japan, accounting for one tenth of the total number of active volcanoes in the world. One quarter of Japan’s land area is covered with volcanic eruptions. These amazing numbers always motivate my curiosity, want to see what happens.
