DEM error effects in 441 Oita. a and b are the vertical deformation velocities derived from ALOS with and without the DEM error correction, respectively. The black dashed lines are the boundaries of the DID. c The LOS deformation time series at P4411 and P4412 derived from ALOS data with and without the DEM error correction and the perpendicular baselines. d The estimated DEM error component. e The hill shade map. f The optical image
