Relationship between the JMA magnitude and the apparent magnitude derived as the sum of the magnitude of EGF earthquakes (3.5) and values of \(\left( 2/3\right) \log \left( R_{r}^{C} M_{0r}\right)\) in Eq. (9). Results in (a, b) show those derived from P and S waves, respectively. Red circles indicate average values of apparent magnitudes for individual JMA magnitude bins
