Abstract

The main aim of this study is to investigate the current vertical crustal movement characteristics and evolution process in Beijing using InSAR technology. In this paper, the InSAR time series analysis method was used to monitor the crustal deformation in Beijing during the period from 2012 to 2015, and to quantitatively reveal the overall deformation characteristics of different areas within the study area. Based on 33 Radarsat-2 wide-mode SAR images covering Beijing, 68 interferograms were formed by optimizing the combination of baselines. Using the FRAM-INSAR technique, the cumulative deformation time series and images along the line-of-sight of the satellite in the 32-phase period were calculated, and the annual average deformation velocity field in Beijing and neighbouring areas during 2012-2015 was calculated. Based on the distribution of active structures in the study area and the distribution of ground subsidence, the relationship between the deformation characteristics of the entire crust and the tectonic activity and land subsidence in the study area was discussed, which provided an effective criterion for accurately carrying out seismic risk assessment in this area.
