Urban subsidence observed by InSAR in Tianjin Region

Abstract: In this paper, we present the results of D-InSAR technique and conventional leveling at selected area in Tianjin city, using 8 ENVISAT SAR images between 17 October 2003 and 17 February 2005.The D-InSAR results show that the subsidence rate reached over 5cm/year (7cm within 16 months) in highly sinking area, and it is consistent with leveling results. D-InSAR is able to provide more details of urban subsidence, and it is supplement to leveling surveys in those areas with sparse leveling benchmarks.

“…Except for Antarctica, all continents include at least a study area: Asia has the largest number of case studies (586). China is by far the most investigated country with 349 subsidence cases analysed using satellite interferometry Ge et al, 2011;Liu et al, 2014b;Luo et al, 2018;Zhang et al, 2007). Iran (Ghazifard et al, 2016;Motagh et al, 2007;Ranjgar et al, 2021) and Indonesia (Bayuaji et al, 2010;Du et al, 2018b;Gumilar et al, 2011) also contributed to a large number of case studies in Asia, with 48 and 31 areas, respectively.…”
