【Abstract】 Based on the moderate and strong earthquake activity and prediction for 10 years after the Datong Yanggao Earthquake in north of North China, the success and failure of earthquake prediction after the Datong Yanggao Earthquake is studied. The practice has tested that the Datong Yanggao Earthquake is not important index of beginning the seismicity of in Shanxi seismic belt, but is signal that seismicity of North China had entered the eighth active episode of the fourth active period. It indicated that North Ch ina (include Shanxi belt) still may occur several moderate and strong earthquakes in future several years.更多还原
