From: A possible scenario for earlier occurrence of the next Nankai earthquake due to triggering by an earthquake at Hyuga-nada, off southwest Japan

Fig. 6

Cumulative slips in simulated Nankai Trough seismic cycles without M w 7 patches of the Hyuga-nada and Bungo channel. Each colored cumulative slip profile is evaluated at the cross with the same color as shown in Fig. 2. Solid and open stars near the steps of the red line denote occurrences of large (M w > 8.5) and small (M w < 8.5) Nankai Trough earthquakes, respectively. Large and small Nankai Trough earthquakes occur alternately; large Nankai Trough earthquakes are accompanied by about 10 m of slip at Kumano-nada (larger steps in red line) and more than 10 m of slip off Ashizuri (larger steps in green line). Small Nankai Trough earthquakes have smaller slips than large earthquakes at both Kumano-nada and off Ashizuri, although the magnitude relation of slips between Kumano and Ashizuri is opposite to the large earthquakes. At Hyuga-nada, about 5 m of after-slips occur corresponding to the occurrences of large earthquakes
