中国位于世界两大地震带——环太平洋地震带与欧亚地震带的交汇部位,受太平洋板块、印度板块和菲律宾海板块的挤压,地震断裂带十分发育。大地构造位置决定,我国地震频繁,震灾严重。20世纪,全球发生的两次导致20万人死亡的强烈地震都发生在我国,
China is located in the intersection of the two major earthquakes in the world, the Pacific Rim and the Eurasian seismic belt, and is squeezed by the Pacific plate, Indian plate and Philippine sea plate, and the earthquake fault zone is well developed. The location of the earth structure is determined by the frequent earthquakes in our country and the serious earthquake disaster. In the 20th century, two strong earthquakes that killed 200,000 people in the world took place in our country.
