From: Spatial pattern in stress drops of moderate-sized earthquakes on the Pacific Plate off the south-east of Hokkaido, Japan: implications for the heterogeneity of frictional properties

Fig. 7

Relationships of magnitudes determined by JMA and the apparent magnitude derived as the sum of the magnitude of EGF earthquakes (3.5) and values of \( \left(2/3\right){\mathit{\log}}_{10}\left({R}_r^C{M}_{0r}\right) \) in Eq. (7), which corresponds to the difference in magnitude between the analyzed and EGF earthquakes if their focal mechanisms are identical. a and b show the results for P and S waves, respectively
