不久前发生的汶川8级特大地震,给我国四川北部及邻近地区的社会经济和人民生命财产造成巨大的损失。地震发生的原因,经专家学者们的初步论证,主要是印度板块向亚洲板块俯冲,造成青藏高原快速隆升,高原物质向东缓慢流动,在高原东缘沿龙门山构造带向东挤压,遇到四川盆地刚性地块的顽强阻挡,造成构造应力能量的长期积累,最终在龙门山北川—映秀地区突然释放,于是引发了这场大地震。 The Wenchuan M8 earthquake that took place not long ago caused tremendous losses to the social economy and people’s life and property in the northern part of Sichuan and its adjacent areas. The reason for the earthquake, the initial argument by experts and scholars, mainly subduction of the Indian plate to the Asian plate, resulting in the rapid uplift of the Qinghai-Tibet Plateau, plateau material flow slowly eastward along the Longmen Shan tectonic belt eastward extrusion, Encountering the rigid block in the Sichuan Basin stubborn block, resulting in the long-term accumulation of tectonic stress energy, eventually in Longmenshan Beichuan - Yingxiu area suddenly released, so triggered the earthquake.
