地震灾害是突发性自然灾害,我国是世界上地震最频繁的国家之一。由于我国地处欧亚板块的东南部,受西太平洋地震带和喜马拉雅-地中海地震带地震活动的影响,地震大多是大陆板块内地震,具有震源浅、频度高、强度大、分布广的特点。从20世纪初到2000年,中国境内发生6级以上地震600
Earthquake disasters are sudden natural disasters. China is one of the most earthquake-prone countries in the world. Because China is located in the southeastern part of the Eurasian plate, affected by the seismic activity of the Western Pacific seismic belt and the Himalayan-Mediterranean seismic belt, the earthquakes are mostly intraplate earthquakes with shallow source, high frequency, high intensity, and wide distribution. . From the beginning of the 20th century to 2000, there were 600 earthquakes with magnitude above 6.0 in China.
