Displacement map (2.5-D) for quasi-eastward direction synthesized from the SAR interferograms in Figs. 2 and 4. Blue lines (A, B, and C) show the linear surface displacements. The orange line (D) shows an independent surface displacement with a rounded pattern. Dashed lines (a, b1–3, c, and d) mark the cross sections shown in Fig. 7. Black stars indicate the positions of discontinuities in the basement identified by seismic exploration (Yokokura et al. 2014)
