Earthquakes are not only associated with faults in their spatial distribution but also migrate from place to place according to certain rules in the course of time. It has been established that the spatial distribution reflects the degree of concentration of tectonic stresses and release of strain energy, while the migration of earthquakes indicates the variation of the tectonic stressfield. In general, the spatial distribution of the earthquakes describes the pattern of relative motion between the f aulted-blocks under static condition, while the migration of the earthquakes under dynamic state.In view of the concentration of tectonic stressfield and its variation, the regularity of earthquake migration and its dynamic state were discussed in connection with the characteristical features of seismic activities in China. By some simple model experiments earthquake migration may be compared with the development of the relevant fractures.
