A magnitude 6.2 earthquake in Ji Shishan County, Linxia Prefecture, Gansu Province, China, caused 118 people in Gansu and Qinghai to be killed. Experts analyzed the serious casualties.Relatively dense.
Comprehensive reports from China New News Agency, Surging News, Observer Network, etc., when the earthquake expert Chen Huizhong analyzed the cause of major casualties, the first reason was that the earthquake was relatively large, and level 6.2 can be regarded as a strong earthquake.Second, the depth of the earthquake is relatively shallow; the third is because the earthquake occurs late at night, and people are sleeping or sleeping; fourth, the earthquake occurs in areas where the population is relatively dense, and the fifth is that the earthquake resistance of local buildings is not as strong as the eastern region.
Hong Yunyin, co -founder of the emergency rescue team of Shanghai Zihuang, also said that the magnitude 6.2 earthquake belongs to the strong level, which can cause significant damage, especially in areas with dense population or low building standards.The depth of the earthquake is 10 kilometers belongs to the shallow source earthquake, which means that the energy loss is less energy loss when the shock wave reaches the surface, causing more damage.The many aftershocks increased the risk of the collapse of the building and the psychological pressure of the residents.
Hong Yunyin said, "This epicenter is very close to Jishi Mountain County, and there are many surrounding villages. And, the night earthquake may cause residents to fail to respond in time and increase the risk of being trapped or injured."
Xu Xiwei, Dean of the Institute of Pioneering and Professor of the Chinese University of Natural Disaster Prevention and Research, analyzed that the Gandong South region is located in the eastern edge of the Qinghai -Tibet Plateau and belongs to the north -south seismic belt.The seismic fracture layer was broken in the north west of the north and north.
The causes of major casualties caused by earthquakes come from various aspects, such as poor seismic resistance in houses, relatively dense population in the earthquake area, and at the time of the rest of the night.
In addition, a magnitude 5.5 earthquake occurred at 9:46 am on Tuesday (December 19), Aushi, Kizilu Suzhou, Xinjiang, with a depth of 10 kilometers.
Chen Huizhong analyzed that the Xinjiang earthquake should not be associated with the Jishi Mountain County earthquake. The population of Aushi, Kizilu Suzhou, Xinjiang, has a small population in the city of Aushi, Aushi.Bring it, it is very far away, so these two earthquakes have nothing to do with.
After the earthquake, Chinese President Xi Jinping made instructions, requiring full efforts to carry out search and rescue, properly resettle the affected people, and work hard to ensure the safety of the lives and property of the people.Chinese Prime Minister Li Qiang also made instructions.
The Ministry of Finance of China and the Ministry of Emergency Management urgently allocated 200 million yuan (RMB, the same below, about S $ 37.29 million) to Gansu and Qinghai provinces on Tuesday, of which 150 million yuan in GansuQinghai 050 million yuan, supporting local earthquake relief.
