Time-Series Displacement of Land Subsidence in Fuzhou Downtown, Monitored by SBAS-InSAR Technique

Figure 3

Mean displacement velocity map over the study area derived by SBAS-InSAR technique. (a) reflects the LOS velocity of the Fuzhou downtown in 2013-2015, while (b) reflects the LOS velocity of the Fuzhou downtown in 2015-2018. The red rectangles indicate the area in which violent subsidence takes place (I-VIII). The local deformation map after enlargement can be seen in Figure 6.
