I am a test to the northeast of Sichuan, a university student, I was a native of Guang'an in Sichuan, I ancestral home is not the urban areas, the following is a rural village, there may be many Chinese people have not visited the rural areas of Sichuan, the earthquake disaster The most serious casualties is the most serious in rural areas, in fact, the urban construction in Sichuan can, but we all know that the northerners, northeast of the house, very thick wall (the wall is 37) and even thick, because the winter and I I ancestral home to a small rural Sichuan, the houses are mud room, this house has very little in the Northeast, the thin wall of the house, my native of Sichuan farmers still rely on the rural side Tiaozhao selling vegetables to the basket, you You know that here in rural Caijia »general seasonal vegetables only 1 to 5 Mao Yi Jin Mao, you Suansuan, the real burden of farmers pick vegetables sold 40, one day Zhengduoshaoqian» why many workers are Sichuan, it » This is because the construction of rural Sichuan is not enough, and too backward .... I feel deep is my ancestral home, the rest of my family was not limited Jiugong television, but I took the laptop to see them, either I Grandmother still alive, I may not know that I am in this life is a native of Sichuan. There is, I and my mother to see my ancestral home, many relatives, remember that families and relatives living in another hilltop on the You know ask them to eat What communications equipment? »Shouted the ~ ~ ~ Yes, through the voice shouted. To 7:00 p.m. after the black days, and you know that I am the ancestral home of these relatives at home is How many lights? «The whole village can not see a few lights ...... I and my grandmother said, Although she has lived in the northeast Ban Beizai, but this ravine in rural areas in Sichuan, regardless of her days at more than black, ....... I can go home feeling Zhangzhemetai the first time in my living room, whose ancestral home is mud, who was a flea bite more than 20 packages, but my grandmother will not bitten, she said humor , Fleas asked her taste, so I do not bite her. Think about now, I native of the old house is still, I really do not know that old house survived the earthquake can I write this ...... We all know that the article is to Sichuan now how backward rural areas, rural houses how dilapidated. What kind of house is unsafe. The earthquake is the hardest-hit rural areas in Sichuan, the number of county Jin Buqu, you know that a Below the number of county village? »You also know how many people have a village?« Really hope that the leadership attaches importance to rural housing construction in Sichuan, to the rate of casualties to a minimum, the hope that such things do not happen again, for all of us together Sichuan silence the victims of the masses!本回答被提问者采纳

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.
