一、制定防震减灾法的必要性地震作为地球运动过程中的一种自然现象,是人力所不能控制和抗拒的,同时,地震也给人类带来了极为惨重的灾难。我国是一个多地震国家,由于地处亚欧板块的东南部,受西环太平洋地震带和喜马拉雅山——地中海地震带地震活动的影响,地震活动不仅频度高、强度大,而且分布很广。本世纪以来,我国大陆发生的7级以上浅源地震(深度小于70公里),约占全球总数的35%,全球一次死亡20万人以上的 I. The Necessity of Making the Law of Earthquake Disaster Mitigation Earthquake as a natural phenomenon in the process of earth’s movement can not be controlled and resisted by human beings. At the same time, the earthquake has also brought extremely serious disaster to human beings. China is a multi-earthquake country. Due to its location in the southeastern Asia-Eurasian plateau, the seismic activity is not only frequent but powerful, and widely distributed, due to the seismic activity of the Western and Central Pacific Seismic Belt and the Himalayas-Mediterranean Seismic Belt . Since the beginning of this century, more than Grade 7 shallow earthquakes (depth less than 70 km) occurred in mainland China account for about 35% of the global total and more than 200,000 people have died in the world
