Deformation in 016 Tomakomai, Hokkaido. a and b are the vertical deformation velocities derived from ALOS and Sentinel-1, respectively. The black dashed lines are the boundaries of the DID. The black solid lines denote the 5 mm/year contour lines without the 0 mm/year lines. c The LOS deformation time series at P0161 derived from ALOS (2006–2011, large circles) and Sentinel-1 (2014–2020, small rectangles) data
