Time evolution of slip velocity in the a Tokai, b Kii Channel, c western Shikoku, and d Bungo Channel segments (points 8–11 in Fig. 4e, f). Unsaturated low-velocity fluctuations represent LSSEs. Saturated high velocities (> 25 cm/y) represent seismic slips induced by Mw 8-class great earthquakes and Mw ~ 7.5 Hyuganada earthquakes in the surrounding area, and there are only nine Mw 6-class earthquakes with spontaneous seismic slips in the Tokai and Bungo LSSE areas (Additional file 1: Fig. S2). Dashed lines indicate the plate convergence rate at each point. Labels R (for rupture) in a and d indicate great earthquakes in the seismogenic zone up-dip from the LSSE areas. Blue and orange dashed lines between c and d indicate Mw ~ 7.5 earthquakes in area Z and Mw 6-class earthquakes in the Bungo LSSE area, respectively. Detailed data for the shaded time periods are presented in Fig. 12
