About 170 km, it doesn't matter! Yesterday morning, Zhang, director of the Monitoring and Forecasting Division of the Earthquake Administration of Anhui Province, said that they made a rough report 3 minutes after the earthquake, reported it to China Seismological Network 7 minutes later, and reported it to the government department 10 minutes later. "Because the source is only 8 kilometers deep, the earthquake is very strong, and with the influence of the Wenchuan earthquake, there are rumors in the province for a time, including rumors in Fuyang, Chaohu, Huainan, Lu' an, Zhangzhou and Zhangzhou; And many people from outside the province also called to ask. From the earthquake to 6: 00 in the morning, the Seismological Bureau received a total of 146 calls. "

Experts say that earthquake prediction is an international problem at present, and those who describe the time and magnitude of earthquakes in a very specific way are rumors. It is rumored that Li Siguang predicted four major urban earthquakes. In fact, Li Siguang only pointed out the main earthquake zones in China. Zhang believes that "Hefei itself is surrounded by Qinling Dabie Mountain Fault Zone and Tanlu Fault Zone, which stretches for thousands of kilometers and can involve Suqian and Lianyungang in Jiangsu." This is an "isolated main aftershock earthquake", and it is unlikely that a series of earthquakes will occur. Even if there are aftershocks, their energy will be attenuated and the magnitude will be lower than 3.5.
