Fig. 7From: Distribution of maximum earthquake magnitudes in future time intervals: application to the seismicity of Japan (1923–2007)Flow of main shocks from 1923 to 2007. Main shocks are defined as “shallow” earthquakes inside the polygonal domain shown in Fig. 1, whose depths are <70 km and which remain after applying the declustering Knopoff-Kagan space-time window algorithm (Knopoff and Kagan, 1977).Back to article page
