[ABSTRACT] The Philippine Sea plate is subducting beneath the Boso peninsula, central Japan, with the Pacific plate underlying the Philippine Sea plate and the complicated tectonic setting is occurred here, followed by numerous seismic events. In order to detect the temporal and spatial pattern of surface deformation in this area， we use the benefit tool of Interferometric Synthetic Aperture Radar (InSAR) method.The raw SAR data which is from 2 C-band acquired by the ERS-1 SAR satellite from 1992 to 1996 are analyzed by using GAMMA, Earth View-3 software commercial software and SIGMA_SAR software respectively. We explored the ability for producing the best interferogram between them. In SIGMA_SAR software, by using Goldstein-Wagner filter, we are successfully increasing Signal Noise Ratio (SNR) on the interferogram image. The DEM 50 m Japan is used to remove the topography effects from InSAR fringes. Our InSAR mapping suggests that subsidence occurs around Mobara region (at the center InSAR image），and the uplift area was detected both in northeast and in Chiba city extending to the northwest of its city. We estimated that our InSAR image has peak amplitude of～5 to 8 cm in line of sight (LOS) direction during 1992-1996 time period. To compare our result, we also analyzed 3 interferograms of JERS-1 data from 6 scenes L band SAR data (1993-1996). Even though the coherency of ERS-1 interferogram is higher　than JERS-1 data pair, in general, we got almost the same pattern displacement from both ERS-1 and JERS-1 data. We also present evidence of the subsidence area from leveling data which recorded during 1993-1997. The radar observations of land subsidence are in good agreement with leveling data. However, the radar data provides a more detailed mapping of both the amplitude and spatial extent of land subsidence.
