CAS researcher at the Institute of Geology and Geophysics, the Qinghai-Tibet Plateau Research Wang Wenchuan 27 pairs more familiar with regional geological structure, in early May has been Wenchuan area. He analyzed that Wenchuan earthquake occurred in the southeast edge of the Qinghai-Tibet Plateau, western Sichuan Longmenshan the center, located in Wenchuan - Timor-mao on the fault zone. Indian Ocean plate northward movement, squeezing the Eurasian plate, causing uplift of the Qinghai-Tibet Plateau. At the same time in the uplift of the plateau, also eastward movement, squeezing the Sichuan Basin. Sichuan Basin is a relatively stable block. Although the main looks Longmenshan tectonic activity is not strong, but the stress may be stored in the process of accumulation to a certain extent, the crust will break down, so the earthquake.
The U.S. Geological Survey also released the news that the earthquake's epicenter and focal mechanisms and Longmenshan fault or a related movement of tectonic fault in line, the earthquake is a thrust to the northeast of the campaign results. From the mainland scale, Central Asia and East Asia, the seismic activity is due to the Indian Ocean plate collision of the Eurasian Plate.
Southern California Earthquake Research Center, Professor Li Yonggang told Xinhua, Longmenshan fault zone is earthquake-prone region of active faults, from the Qinghai-Tibet Plateau deep eastward flow of material disruption to the Sichuan Basin, the upward movement, which both border For the fault plane. If the fault movement a few centimeters a year, once every 50 to 70 meters, the accumulation of stress and energy can be generated from a magnitude 7 earthquake above. As the source shallow, and focal mechanism for the eastward thrust of the campaign, coupled with soft soil earthquake zone, seismic waves will spread eastward very long, making far to Shanghai and Beijing and other cities have generally felt.
British Geological Survey earthquake monitoring and information service center director Brian Bapu Di in the Xinhua News Agency reporters Dian Huacai and Fang Shiyue, from the geological structure, the earthquake and the Himalayan collision zone on, "is clearly the Northeast - to the Southwest Longmenshan fault zone in the compression of the result. "
France's Institute of Geophysics, geologist Paul Daboniye the media said about 5,000 years ago, the Indian Ocean plate drift northward, collided with the Eurasian Plate after diving to the latter below, which formed the Qinghai-Tibet Plateau. Qinghai-Tibet Plateau is still squeezed by the two plates, making the Qinghai-Tibet Plateau and the surrounding areas into intensive earthquake zone.
