This atlas can be divided into three parts: The first part is the epicentral distrbution in China and its vicinity. It shows the epicentral distribution of earthquakes with different magnitudes for historical and recent earthquakes (1970-1986), showing the general features of seismic activity in China; The second is the epicentral distribution series maps in various seismic regions in China. The developing period of seismic activity are shown in various time levels according to the magnitude range in different seismic regions, this is favourable for analyzing local seismic activity in detail. Besides north China, Northeast China, South China, Northwest China, Southwest China, Xinjiang province and xizang (Tibet) seismic regions, Seismic activity in Beijing-Tianjin-Tangshan-Zhangjiakou in North China was drawn alone, considering the regquirement of earthquake prediction in the Capital Cycle and the important meaning. Seismic activity in this area was described in more detail. The third part is the parameter distribution of seismic activity in the mainland of China and in most seismic areas. Seismic regions are divided mainly according to seismic activity distribution and geological tectonics. The calculation method of seismic activity, the physical meaning are listed in the references.
