Fig. 5

a Estimated total slip for the 2018–2023 period. The colors indicate the magnitude of the aseismic slip, whereas the arrows show the aseismic slip vector. The contour interval is 10 cm; that in the inset is 5 cm. The descriptions of the other symbols are the same as shown in Fig. 4. b–i Time evolution of moment release. Each area of moment calculation is designated by solid lines in (a). b Kii Peninsula of (1). c Kii channel of (2). d central Shikoku of (3). The vertical broken lines indicate the dates of the s-SSEs in northwest Shikoku. e Bungo of (4). f Northern Hyuga-nada of (5) g Southern Hyuga-nada of (6). The vertical line indicates the date of the 2019 Hyuga-nada earthquake. The slip distributions for the shaded periods are shown in Additional file 1: Fig. S9. h Off the Ohsumi Peninsula of (7). The vertical line indicates the date of the 2022 off-Ohsumi earthquake. i Off Tanegashima of (8). The vertical line indicates the date of the 2019 Tanegashima earthquake. The green translucent box shows the period of short-term slow-slip events off Tanegashima
