The G-R relation between the earthquake magnitude and frequency has been an important premise in seismological study, but its actual distribution often deviates from its theoretic result.
And then the predicted earthquake magnitude in seismic risk areas and the happened magnitude have also been taken into account, R-value of different magnitude levels have been calculated.
