Shock thousand li in Wen Sichuan
Staff reporter Ma Hui king the intersection of tinkling of pieces of jade and leaf build King reveal the report of Beijing generation At 35 past 14, seven storeys for some mansion near Beijing Chang'an Avenue Xiushui Street. "The building is shaking. " Mr. Sun claims on the seat. In the twinkling of an eye, such dizzy sense is passed to all persons in the office. " earthquake " --Someone has shouted. Indeed, the earthquake has come. Determine, at 28 past 14 on May 12 Beijing time, in Wen Sichuan the county (31 degrees in the north latitude of Sichuan according to China's national seismograph station network, 103.4 degrees of east longitudes) The magnitude happening is 7.8 grades. Shortly after that, 3.9 magnitude of earthquake have taken place too in Tong Zhou District of Beijing, the seismaesthesia involves a lot of places in China, there is seismaesthesia in Chongqing, Shanxi, Shaanxi, Hubei, Beijing and other places. The state apparatus makes a response to calamity immediately, after the earthquake took place in Wen Sichuan of Sichuan, the General Secretary Hu Jintao makes the important instruction immediately, demands to rescue the wounded as soon as possible, guarantee the life security of the people of disaster area. Premier Wen Jiabao is rushing towards the disaster area and guiding the disaster relief work. All relevant ministries and commissions have started a series of emergency measure. According to the news which committee's office of natural disasters relief of the country releases at 19 o'clock on the same day, up to 18 on May 12, the earthquake has already led to the fact Sichuan, Gansu, Chongqing, 107 people of Yunnan die, 34 people have been injured. The Sichuan earthquake of 7.8 this Sichuan Wen of the magnitude, magnitude determination, it is repeated to go through some. At first, the magnitude that the media reveals is 7.6 grades. Shortly after the earthquake takes place, www.xinhuanet.com that Xinhua News Agency sponsors broadcasts an information in the form of news flash: The electricity is determined according to China's national seismograph station network on May 12 in Beijing, 28 past 14 on May 12, 2008 Beijing time, in Wen Sichuan county of Sichuan (31.0 degrees in the north latitude, 103.4 degrees of east longitudes) 7.6 magnitude of earthquake take place. Shortly after that, www.xinhuanet.com has released the latest information, there is a earthquake the rank will be heightened to 7.8 grades. "Judge tentatively, this earthquake of Sichuan should be a simple source earthquake at present, such release of energy otherwise will not come out. " Xu ShaoXie, academician of Chinese Academy of Engineering, says. As the researcher of China Seismological bureau geophysics research institute, Xu ShaoXie has taken the post as the Vice President of Seismological Society of Chinese, international earthquake disaster and predicting committee's Vice President, duties such as the physical committee member of executive office of association,etc. within international earthquake and the earth, specialize in the monitoring of the earthquake incident, differentiate. In letting to continue Xie's impression, this magnitude is still greater, " besides heavy earthquake of Tangshan, I a strong one have, take place in Qinghai, Tang Gu, Sichuan Province of juncture drawing the heavy earthquake of the mountain pass will it be November 14 2001 in the memory, have reached 8.1 grades that time " . Sichuan Province where the earthquake takes place this time, lie in and like horses and draw refinedly - the Mediterranean earthquake is taken, in view of geological structure, it belongs to earthquakes in theory to be high to take place the area. Take place in Wen Sichuan county of the earthquake on Songpan earthquake zone of the heavy earthquake of 1976 this time, Songpan area is in the east of the north mountain of Longmen to converging the position of structural belt to structural belt, east-west structural belt and north and south of Ming mountain of west Qinling Mountains, the terrain structure is complicated. Songpan earthquake zone is a tectonic earthquake, because the earth moves and changes ceaselessly, thus inside produced the enormous crustal stress and acted on the earth's crust. Under the long-term slow function of crustal stress, lead to the fact the rock stratum of the earth's crust happens crookedly and deforms, the local stress will make the rock stratum rupture and move by mistake while exceeding intensity that can be born of the rock, its enormous energy was released suddenly, formed the tectonic earthquake. And according to the introduction of Zhang HongWei, press spokesman of China Seismological bureau, this earthquake is large in intensity, the spread area is wide, including there is seismaesthesia inside in province and city such as Ningxia, Qinghai, Gansu, Henan, Shanxi, Shaanxi, Shandong, Yunnan, Hunan, Hubei, Shanghai, Chongqing,etc.. "The reason why all parts all feel this time, because the magnitude of this earthquake is heavier to some extent, it is longer, decay slower, so the fluctuation of the earthquake walks farther. " ShaoXie Xu say " but everybody feel strong, should until work there is a relation in high building. " Shortly after the earthquake took place in Sichuan, also the low rank earthquake takes place in Tongzhou of Beijing. Determine, at 35 past 14 on May 12, 2008 Beijing time, in Tong Zhou District (39.8 degrees in the north latitude of Beijing according to the national seismograph station network, 116.8 degrees of east longitudes) 3.9 magnitude of earthquake take place. This Beijing earthquake and Wen's Sichuan earthquake are only separated by 7 minutes, is there a cause and effect connection between the two? "Can't confirm yet, are hard to tell now. Perhaps relate between the two, but might not be a decisive factor, this also needs further research and analysis. " Xu Shao Xie claims. And the aftershock takes place to Wen after the Sichuan earthquake, the earthquake expert expresses " has possibility in theory " . In fact, after 7.8 magnitude of earthquake of Wen Sichuan, have had a series of aftershocked that has taken place already. Chief Hu Ping's introduction of meeting an urgent need according to Beijing Seismological Bureau, the sports meeting of the earth's crust releases a large amount of energy, the above- 7th -class earthquake will bring great destruction strength. The vibration of the lithosphere of earthquake, a way of the earth plate of moving constantly accumulating and release energy. Often accompanied by a series of less aftershock after a strong earthquake, some earthquakes are that pair is shaken. The earthquake of this Sichuan Wen Sichuan county is with several aftershocks after the strong earthquake. "There should be some in the aftershock, because this magnitude after all is 7.8 grades, may happen in a few days subsequently, the magnitude is possible in 5- 7 grades. The locality should consider the question of the aftershock, ready. " Xu Shao Xie expresses. Or already actually had a sign before shaking, before the earthquake, already there are some signs in some areas in Sichuan, but is just ignored by local related departments. May 10, once until " whether hundreds of thousands of toad beat and debark to look for new ' house ' " " the West China City Newspaper " It is a question, report: A few days ago, the southwest town wingceltis Kimura of Mianzhu had presented the large-scale toad to migrate, hundreds of thousands of all kinds of toads walk on the highway near a pharmaceutical factory on a large scale, a lot of are killed by vehicular traffic, is stepped on to die by the pedestrian. "Close and numerous toads have been covered with the village one, the toad probably has 1.333 hectares to gather the area, in the vegetable garden distributed in peasant around the pharmaceutical factory, vacant lot. " The toad appearing in a large amount, makes local villagers think that there will be bad signs that appear, it is " omen of natural disaster " . After the municipal forestry bureau of Mianzhu receives the report, catch up with and send to the locality. Explain according to the persons in charge of this office, the reason why will present so many toads, relate to terrain here, here is in low-lying land section of farmland, very suitable for toads and survive, it is the the moon that breeds season now, rainfall in addition, escape canal water temperature for two days is slightly high continuously, are very suitable for toads and lay eggs and hatch. In view of the above, this office draws the conclusion, this kind is large-scale Toad move actually" It is a good thing " ,Prove the ecological environment of Mianzhu is better and better. And according to the introduction of earthquake expert, before the strong earthquake takes place, the body of rock is under the function of crustal stress, meet an emergency in the stress and accumulate gradually?
