Haizi, large and small, formed after the earthquake, gradually burst. Only two large and small Haizi, Gong Peng and Bailazhai, have been preserved so far, and people collectively refer to them as "large and small Haizi", which is today's Diexi Haizi.
Since then, this Qiang city in Diexi, northwest Sichuan, located on the eastern edge of the Qinghai-Tibet Plateau, disappeared from the center of Diexi Town, a battleground for military strategists since ancient times, and was erased from the map with a huge earthquake.
It is hard for people to believe that this frontier town, which was founded in the Tang Dynasty and has a history of more than 1000 years, was so easily swallowed up by the mother earth who gave birth to it and raised it at the moment when the white ground light flashed by. Since then, its name has never been found on the map, but the map of strong earthquakes in China has drawn a big red circle for it. Landslides, ground cracks, cities sink, people die ... the accumulation of thousands of years is completely destroyed in an instant. The earthquake was felt in Xi 'an in the north, Wanxian in the east, Aba in the west and Zhaotong in the south. Beijing, Nanjing Seismic Station and most seismic stations in the world-Osaka, Mumbai, Copenhagen, Hamburg, Paris, Tunisia, Sydney, Toronto, Ottawa, Honolulu and other places have also received this terrible seismic wave. According to statistics, about 6800 people were killed in the earthquake zone. This is the most painful earthquake in Sichuan in modern times, leaving an extremely terrible page in human history.
While Diexi was devastated, seismographs all over the world also received ground motion signals, and the seismic waves of this disaster were recorded by Bird Peak and Nanjing Seismic Station almost simultaneously. This terrible seismic wave has been detected by more than 0/000 seismic stations in the world, such as Manila, Daban, Medan, Mumbai, Copenhagen, Hamburg, Honolulu, Paris, Tunisia, Sydney, Toronto, Wellington, Ottawa and La Paz. ...
After the earthquake, the house collapsed and it rained cats and dogs that night. The earth is still shaking from time to time, and stones roll down from time to time on the mountain. Disaster continues to ravage the earth. People who survived the earthquake panicked. Sleeping in the wilderness, struggling with hunger and cold.
During the earthquake, the Minjiang River was blocked by rocks falling from Yin Ping Cliff, Bridge and Diexi on both sides of the Minjiang River, and three dams suddenly appeared. The main stream of Minjiang River was cut off, and the river above Yinpingya Dam was forced to surge northward, carrying sand and stones, and flooded to Shawan and Monkey Village two hours later. Two days later, it flooded into Pu 'an, and four days later, the lake poured into the spring cliff, flooding Kannonji, and the water level rose by more than 300 meters. From then on, a Pinghu with a width of about 30 miles appeared in the alpine valley, named Shanghai Zi. At the same time, there were many landslides in Songpinggou, Shuimogou and Yuerzhaigou, which formed eleven Haizi, and flooded a large number of fields and houses.
More than a month after the earthquake, the upper reaches of the Minjiang River were raining continuously, the river surged, and the lakes in Haizi Lake increased day by day. 65438+1At 7 o'clock on the evening of October 9, Diexi Haizi Waterfall collapsed and accumulated water gushed out. The waves are as high as 20 feet, the walls stand down and the turbid waves fly. The rapids rushed to Maoxian and Wenchuan at a speed of 30 kilometers per hour. At 3 am the next day, the flood peak still rushed to guanxian with a drop of 4 feet, and the banks along the river were swept away by the flood. Dozens of villages along the Yangtze River in Maoxian County, Wenchuan, such as Dadingguan, Shidaguan, Musubao, Songjibao, Changning, Xiangou, Huaguoyuan, Shuicaoping, Daheba, Weizhou, Qipaigou, Mianchi, Xingwenping, Taipingyi and Zhongtanbao, were destroyed. Rivers and channels inside and outside Dujiangyan were washed into pebbles, and Hanjiaba, An Lan Bridge, Xingongyuzui, Jingang levee, flat water tank, Sha Fei weir, herringbone dike, channel engineering and flood control dam were washed away. 1933 There was no earthquake of magnitude 7.5 in Maoxian, Sichuan. Neighboring places such as Chongning, Pixian, Wenjiang, Shuangliu, Chongqing and Xinjin were greatly affected. According to incomplete statistics, the death toll is about 2500.
