Coseismic and aseismic slip distributions of M > 7 earthquakes around the Miyagi-ken-Oki (MYG) patch. Coseismic slip is extracted when slip velocity (V) > 1 cm/year. Aseismic slip is the slip remaining after removing coseismic slip from cumulative slip over the three years from the rupture initiation time of each M > 7 earthquake. a Map view of simulated coseismic slip (> 1 m) and aseismic slip (> 1 m) distributions of the MYG earthquakes shown in Fig. 5. The coseismic slip of the MYG earthquakes before the M ~ 9 earthquake (10 events; Fig. 5a–c, f–l) is indicated in blue, and light-blue lines show the aseismic slip following these earthquakes. Among the light-blue lines, the dotted lines indicate events that occurred just before M ~ 9 earthquakes with only one year of cumulative slip (Fig. 5c and l). The reason for the one-year duration is owing to the shortest time interval of < 3 years between the MYG earthquake and M ~ 9 earthquake. The coseismic slip of the MYG earthquakes after the M ~ 9 earthquake (2 events; Fig. 5e and n) is indicated in red, and pink lines show the aseismic slip following these MYG earthquakes. Black crosses represent the points shown in Fig. 7. b and c Slip profiles of coseismic slip and aseismic slip distributions of the MYG earthquakes shown in Fig. 5 along gray lines (C–C′, across the MYG patch center; F–F′, along 35 km depth) in the map panel
