2008年四川地震发生在2008年。它被称为汶川大地震,以中国新川的汶川县命名,那里是地震的震中。加州理工大学构造观测站的科学家们表示,2008年5月12日袭击中国的这次毁灭性地震是地震易发区地震序列中的一次,可能会重复发生。它发生在欧亚板块和印度板块由于摩擦而逐渐变形的地区。

这场持续了5000多万年的碰撞促进了整个中亚地区的高山和地震活动的发展。亚洲和印度之间的密集圈层区域范围广,正经历着巨大的变形和应变。正是这种压力导致了新川地震,并可能导致其他地震。显然,印度一直在向北转移。这种位移每年以4毫米的速度测量,几乎相当于每年八分之一英寸。这一转变导致了龙门山山脉的不断上升,形成了西藏东部的边界。

新川地震的震级约为7.9级,它破坏了龙门山断层的正面,龙门山断层标志着西藏的东角,四川盆地在这里与龙门山交汇。断裂开始于成都市西北部山区,在接下来的50秒内,断裂向东北方向延伸了100英里,测试了山脉前方的大陆。断裂南缘的运动基本为倾滑运动,导致山脉抬升和新川盆地的沉降。

The 2008 Sinchuan earthquake occurred in 2008. It is known as the Great Wenchuan Earthquake, named after Wenchuan County at Sinchuan in China, which was the epicenter of the earthquake. Scientists of Caltech Tectonics Observatory stated that this devastating earthquake that stroke China on May 12, 2008 is one in the earthquake series of the earthquake prone region and may be repeated. It occurred in a region which is gradually deforming because of friction between the two tectonic plates: The Eurasian Plate and Indian Plate.

The collision that has been on for over 50 million years has contributed to the development of high mountain ranges and seismicity visible across Central Asia. The region of intense circles between Asia and India covers a broad region, which is undergoing huge deformation and strain. It is this strain that resulted in the Sinchuan quake and might lead to others. Evidentially, India has been shifting northwards. This shift measures at a rate of 4mm every year and it equals to almost eighth of an inch annually. This shift results in the ongoing rise of the Longmen Shan mountain range, which forms Tibet’s Eastern Border.

The Sinchuan Earthquake had a magnitude of about 7.9, which ruptured the front side of the Longmen Shan fault that marked the eastern corner of Tibet, wherein the Sichuan Basin meets the Longmen Shan Mountain. The rupture of the fault began in the northwest mountains of Chengdu city and during the next 50 seconds, the rupture traversed a 100 miles towards the Northeast direction, testing apart the landmass in front of the mountain range. Motion among the fault’s southern edge was basically dip slip, which resulted to an uplift of the mountain range and the Sinchuan basin’s subsidence.
