Fig. 2

Detrended position time series at selected Global Navigation Satellite System (GNSS) sites relative to the 950388 site (the locations of these sites are shown in Fig. 1a and c) averaged over a 3-day period. EW, NS, and UD indicate east–west, north–south, and up-down components with eastward, northward, and upward positive directions, respectively. The red lines show the transient computed from our optimal model. The vertical broken line in (j) indicates the date of the 2022 Ohsumi earthquake. The blue translucent boxes show the periods of long-term slow-slip events (l-SSEs), while the green translucent box in (k) and (l) shows the periods of short-term slow-slip events (s-SSEs) off Tanegashima. a 021013, b 950,422, c 03P216, d 021051, e 940,083, f 051142, g 950,437, h 021088, i 02P211, j 960,716, k 960,724, l 950,492
