Fig. 2

a Coseismic slip distribution in the X–Y plane from Nakata et al. (2012). Contours indicate depth (in km) of the upper surface of the descending plate (Baba et al. 2002). b True image of afterslip distribution in the X–Y plane for a duration of 80 days. Subfaults were coarsely relocated from Nakata et al. (2012). c Depth profile along X = 205 km (gray vertical shadow PQ in Fig. 2b). Gray line and the left axis show coseismic slip (Fig. 2a). Black line with dots and the right axis show afterslip (true slip, Fig. 2b). Blue line shows afterslip estimated from previous inversion analysis (Nakata et al. 2014) (Fig. 2f). d Map of Japan: the inset represents the study area shown in Fig. 2e. e Station distribution used for calculating displacements. Existing GNSS stations (green dots, 156 stations) and planned stations on ocean floor (blue dots, 21 stations). f Afterslip distribution in the X–Y plane estimated from our previous inversion analysis using stations shown in Fig. 2e (Nakata et al. 2014). The maps were created using the software Generic Mapping Tools (Wessel and Smith 1998)
