sphere of influence
In earthquake areas, city walls, official residences, temples, etc. Once destroyed, Tancheng collapsed to the ground, and there were no houses in Juzhou, accompanied by large-scale landslides, subsidence, water gushing and sand spraying. When the earthquake happened, it was like a ship's roof, like an orange falling up and down, collapsing into a ravine and spinning into an abyss. Sand and stones rushed into the well, trees on the side of the ground died and hundreds of valleys fell. * * * has killed more than 50,000 people, and there are dead bodies everywhere, and many people can't be buried. Where the village is valued, the stench is everywhere. Rainstorm and scorching sun, plague and dysentery followed, and people were distracted. More than 500,000 square kilometers around the epicenter 150 counties were damaged to varying degrees, more than 50,000 people died, and the induction radius was more than 800 kilometers. There were 6.5-7. 1 aftershocks after the earthquake.
The earthquake zone starts from Juxian County in the north, reaches Xinyi in the south, and is distributed along the Yishu fault zone in the northeast. The intensity of some areas in Tancheng County and Linshu County reached 12 degrees, and the intensity of other areas reached XI degrees. When the earthquake happened, the trees on one side of the ground were covered and hundreds of valleys fell. Battlements, public rafters, official residences, temples, etc. All were destroyed at the same time, the landslide was cut off, the ground turned into a deep, and sand poured into the well. Tancheng towers and village temples collapsed like the ground, and ground fissures gushed out, spraying as high as two or three feet. Ground fissures or cracks are too wide to cross, or cracks are too deep to view, and thousands of towns in Li Jiazhuang are merged; Yizhou people have no space, the water depth of the flat land is more than ten feet, the water in the well is several feet high, and the ground is cracked; There is no house in Juzhou, and the landslide in Ma Zi is scattered. The building is split in two, Yangu, Cyclone Flower and Maqi Mountain are split in two, and the four towns in the city are split everywhere. There are dead bodies everywhere, and many people can't bury them; Heavy rain and scorching sun, plague and dysentery followed, and people were evacuated.
X-degree area reaches Zhucheng in the north, Xinyi in the south and Mengyin and Feixian in the west. Government houses in Guo Cheng were completely damaged, and countless residents were killed. There were landslides, ground fissures and black sand water, and the water in the apartment was several feet.
Jiudu District reaches Weifang and Yidu in the north, Pixian and Shuyang in Jiangsu Province in the south, Rizhao and Jiaoxian in the east and Yanzhou and Zouxian in the west. There are no rotten official houses, no many human and animal casualties, no ground fissures and landslides, and no gushing water in the sand.
Badu District covers an area of 90,000 square kilometers from Jinan to Changyi and Jimo in the north, Yancheng and Lianshui in Jiangsu in the south and Weishan, Jining and Taian in the west. Countless city walls and official buildings were toppled, and most people and animals were crushed to death, resulting in ground subsidence and landslides.
Area VII starts from Jiaodong Peninsula in the north, reaches Huimin and Dezhou, reaches Huaibei and Bengbu in Anhui Province in the south, reaches Xuyi, Baoying and Dafeng in Jiangsu Province, and reaches Heze and Shangqiu in Henan Province in the west, covering an area of nearly 200,000 square kilometers. How bad battlements and houses are, people crushed the dead and the ground cracked into black water.
Area VI starts from the Yellow River Estuary in the north, reaches Anqing and Xuancheng in Anhui Province in the south, reaches Shanghai in the south, reaches Jixian and Qiuxian in Hebei Province in the north, and reaches Anyang and Zhengzhou in Henan Province in the west, covering an area of nearly 400,000 square kilometers. It is generally recorded that houses are often dumped or thrown at people.
Description of ancient books
There are records in the county chronicles of dozens of counties in Shandong Province, such as Yishui County Chronicle "Thousand Houses Collapse" and Zhangqiu County Chronicle "Longshan Landslide". Pu Songling, a famous novelist, gave a vivid description in the article Earthquake, the second volume of Strange Tales from a Lonely Studio. The following quotation is from Earthquake: On June 17th, the seventh year of Kangxi, a great earthquake occurred. In (Editor's Note: Linzi today), Fang and his cousin Li drank a candle wine. Suddenly I heard thunder, coming from the southeast and heading northwest. Many people are horrified and don't understand why. In a few cases, the wine glasses were knocked over and the beams and rafters of the house staggered. Take care of each other. After a long time, we know that earthquakes and diseases often appear. I saw pavilions, servants rising, walls falling down and houses falling down, and children singing female trumpets, making a noise. People are dizzy and can't stand up, sitting on the ground and turning sideways. The river overflowed and the whole city crowed and dogs crowed. After a while, I will make a decision. Depending on the street, men and women meet naked, competing to confess and forgetting that they are naked. Later, I heard that a well can't be tilted, a tower moves easily from north to south, Qixia Mountain cracks, Yishui sinks, and is several acres wide. This is really weird.
Earthquake consequences
● Geology
Landslides, ground fissures, collapses and other ground deformation phenomena are distributed in most areas of Shandong Province and northern Anhui Province. The deformation zone extends from north to south120km, in which the strong fracture zone starts from Banquan in Junan County in the north and reaches Guiyimozi in Tancheng County in the south, with a length of about 70km. Due to the large-scale rise and fall of the surface, the flat land was flooded by overflowing groundwater, the beach in Ganyu County, northern Jiangsu Province rose, and the sea water in the Yellow Sea retreated by 30 miles. More because of the collapse of houses in dozens of counties.
● Personnel
Human and animal casualties are very heavy. According to historical records, the death toll was more than 50,000, including more than 20,000 in Juxian, more than 20,000 in Linyi 1.2, and more than 8,700 in Tancheng.
● Economy
The earthquake alarmed the ruling and opposition parties, and Kangxi ordered the relevant departments to discuss in detail and give relief respectively. The annual rent of 40 states, counties and health centers, including Yizhou, Shandong Province, was exempted, with 227,300 yuan of silver, and officials were sent to provide relief.
correlation studies
1956, the Earthquake Working Committee of China Academy of Sciences collected and sorted out a large number of earthquake historical materials. 1960, Mr. Li Shanbang determined that the earthquake was Tancheng M8. From 1970s to 1990s, Gao Weiming from the Analysis and Prediction Center of the State Seismological Bureau, Li Jialing, Lin Zhixiang, Chao Hongtai from the Shandong Seismological Bureau, Zheng Langsun from the Earthquake Office of Linyi Administrative Office made many field visits to the earthquake, and determined the seismogenic fault. Ji Tongren and Xu Xueyan supplemented and collected relevant historical materials. The epicentre of this earthquake is Tancheng-Linyi area, which is located in the main area of the famous "Tanlu fault zone" in China. The earthquake was caused by the activity of the land fault zone.
seismogenesis
In a certain time interval, the long-term erosion of Doujialing-Mercury Mountain Barracks will inevitably lead to intermittent balance compensation, and the instantaneous uplift will inevitably lead to the occurrence of earthquakes, which is the background of the formation of earthquakes in this area. The direct cause of the earthquake is the hidden explosion of the trap, because the hidden explosion can form magma channels, which can make the high-density magma invade continuously and play an effective role in balance compensation. The geological background of Tancheng earthquake polar region has concealed explosion earthquake trap and natural gas accumulation.
Earthquake relics
The Maipo earthquake active fault site in Tancheng, Shandong Province was officially approved as a national typical earthquake site by the Seismological Bureau of China. Next, Shandong Province will carry out protective development of the site.
The Maipo seismic active fault zone in Tancheng County is located in the middle of the Tancheng-Lujiang fault zone, the largest fault zone in eastern China, where the Tancheng M8.5 earthquake occurred. 1668.
The latest situation:
July 13 19: 03 It was learned from the Earthquake Administration of Rizhao City that an earthquake of magnitude 2.9 occurred in the northern part of Juxian County, causing no casualties or building damage. Some residents in Juxian county felt the earthquake. It is known that the earthquake occurred in the north of Chengyang Town, Juxian County, with the focal point at 35.6 1 north latitude and 018.80 east longitude.
