Fig. 7

Mean velocity field calculated by the time-series analysis using corrected interferograms. The area of this figure is indicated in Fig. 3. Note that the color scale ranges from − 5 to 5 mm/yr, much smaller than Fig. 3. Red line (AA’) shows location of the profile in Fig. 8. Two red circles (X and Y) indicate the sampling points of cumulative displacements in Fig. 10. Black lines indicate the active faults. UKF: Ushikubi fault. MSF: Mozumi–Sukenobu fault. ATF: Atotsugawa fault. Spatial gradient in the LOS velocities across UKF is larger than that across ATF and MSF
