| Abstract: | The G-R relation lgN=a-bM (1954) is an empirical formula used widely in the seismicity research. But the linearity of b curves has great difference in different time and space domains. An interested question in this paper is that in how large
a space-time-strength domain the b value has certain physical connotation. This study told us that we can get optimal statistical results of b value in those space-time domains which can develop correspondent strong shocks with magnitude interval (M
s≥8.5, 8.0≤M
s<8.5, 7.0≤M
s<8.0). Thus, the possible seismogenic areas in which strong shocks with different magnitude intervals develop can be inferred
in different regions of the mainland of China. Finally, some new problems are proposed, such as the delimitation of seismic
province, the seismicity parameter determination in seismic hazard analysis and in earthquake predictions by using b value.
