time, etc. earthquake conditions consistent with reservoir induced seismicityFan Xiao Wenchuan earthquake in the eyes of the "abnormal". Historical data show that the historical seismic record Longmenshan seismic belt never more than 6.5,veste barbour, the earthquake in China in the north and south,cheap toms outlet, the Longmen Shan intensity and frequency of seismic activity is relatively weak,oakley sunglass outlet, academia its long-term forecast for seismic intensity zoning 7 degrees (the earthquake actually reach 10-11 degrees).Fan Xiao believes that Zipingpu reservoir and the earthquake has a special relevance and space. First of all, it belongs to induce a high probability of an earthquake of high dam, and is located on a fault zone has a strong earthquake activity; its epicenter near the reservoir area, earthquake time is for the most dangerous thrusts drawdown periods; their After the earthquake time Zipingpu reservoir began filling in three years after the first water to the normal high water level of two years, in line with the conditions of reservoir induced earthquakes are retarded.Fan Xiao lists 23 Chinese scholars thesis topic and research five foreign scholars are involved in both associations.He also noted that a study in 2009 found that the earthquake's epicenter is located just by the Zipingpu Reservoir water mill - on Miaoziping fault, and the entire fault zone is actually an intersection in a gentle break down fault system level. Reservoir for the next penetration, will have an impact through surface cracks in any one place for the entire fault system.Three questions: reservoir geological activity have so much influence? Substantial drain water quickly,tiffany, like a strong massage to the earthquake faultZipingpu reservoir have such a big impact on the geological event? Fan Xiao said it was quick and substantial water and drainage reasons. September 2004 began to water,veste barbour homme, to October 2006 reached 875 meters the highest water level, water level rises 123 meters in just two years and one month. Among them,barbour femme, only the water level in September 2005 to December it increased by about 80 meters. "This is the high dam at home and abroad are rare in.""So quickly and dramatically raise the water level.
breaking the original balance. In addition, the water would seep into the cracks filled the void in the library rock bottom, it will generate additional pore water pressure, water infiltration, soaking and softening the rock pore water pressure on the fault plane lubricates, making it easier to rock cracked, broken more easily extended. Impact of this pore water of fault activity,red bottoms, should be greater than the impact of the water itself pressures.Dams,nike tn officiel, the greater the storage capacity, the more likely to cause an earthquake? Fan Xiao said, speaking from the probability to have this law,tn pas cher, but not entirely proportional relationship. According to incomplete statistics,tiffany milano, over 200 meters of the dam reservoir induced seismicity world ratio of 34%. In China, the height of 100 meters above the reservoir storage capacity of 10 billion cubic meters or more, earthquake ratio of about 30%."30% is in many situations imperfect Reservoir monitoring data obtained," Fan Xiao said that since 2004 the State Council promulgated the "Regulations seismic monitoring" since the height of 100 meters or more, the capacity of 500 million cubic meters or more and may induce earthquakes above five reservoirs are generally established a dedicated seismic monitoring network. In recent years,tiffany outlet, a large number of observational data suggest that these large reservoir induced seismicity ratio of 100%."So for the high dam,tn pas cher, it does not actually induce an earthquake-induced problems, but does not induce destructive earthquakes or earthquakes induced problems." Fan Xiao said.Second question: Wenchuan earthquake and Zipingpu reservoir related? Epicenter location.
for the heads of government from the chairman of the CPPCC to break with tradition and convention cadre officials serving way,ray ban sunglasses for sale, illustrates the central in the selection of the executive heads of the provincial level of government, but also hope that these cadres and officials can be more Some experience in governance, and to the "political consultations" as the imperatives of the CPPCC has the potential and advantages in this regard.In addition,vault oakley, the local elected 12 new two sessions of the provincial People's Congress. In addition to part-time member of the Politburo provinces (municipalities) appointed secretary of the province,tiffany milano, as well as Tibet,Christian Louboutin Online Store, Xinjiang Autonomous Region,nike tn officiel, the rest of the province by the party committee leaders concurrently. (Zhang Guangzhao Chenzhen Kai)(Original title: Provincial chief mode of getting a promotion institutionalized The day before yesterday, Sichuan Provincial Bureau of Geology and Mineral Resources Regional Geological Survey Team engineer Fan Xiao guest Guangdong Science Center and co-organized by the Southern Metropolis Daily Xiaoguwei scientific forum,nike tn soldes, popular science knowledge reservoir induced earthquakes. After analyzing the relationship between earthquake ZiPingpu reservoir, Fan Xiao proposed upstream of the Yangtze River in western China a dozen high dam "has evoked strong earthquake risk" and called for a moratorium with a significant risk of a number of large power plants in the region project and approval.I asked: bigger and more easily reservoir induced earthquakes? Large reservoir induced seismicity 100% The question is whether induced earthquakeWhy would reservoir induced seismicity? Fan Xiao introduced after impoundment changed the situation by force library at the end of faults.
