Fig. 6From: High-resolution 3D earthquake forecasting beneath the greater Tokyo areaSectional images of KM9-values. The units of the log-scale color legend correspond to the reference value \(\bar{K}_{M9}\) in Table 1 (Reference). Small black circles and dots are the earthquakes of M4 and larger, that occurred near each plane and plate surface, throughout the entire period 1923–2015. White circles are the earthquakes of M4 and larger, that occurred within the month right after the M9 event. Both black and white markers increase in size with event magnitude: the white circles are five times larger than the black marks for events of the same magnitude. The depth ranges used in plotting the both disks circles are the same as those in the Fig. 4 captionBack to article page
