(a) Elevation change along a south-to-north path from Guangrao to Dongying (L1-L1’ in Fig. 1). (b) Elevation change along a west-to-east path from Longju to Dongying (L2-L2’ in Fig. 1). Range change data are projected onto a vertical unit vector. Gaps in the InSAR profile reflect regions where the pixel is incoherent, therefore, no data are available.

YD01, the bedrock mark, is the reference point of spirit leveling. YD14, the benchmark, is the center of the square reference area, with 500 m on a side for interferometric synthetic aperture radar (InSAR). D18 is the share benchmark of the two level lines (Shandong Provincial Lubei Geo-engineering Exploration Institute, SPLGEI). The four faults, F1 (the Chennan fault), F2 (the Gaoqing-Pingnan fault), F3 (the Shicun fault), and F4 (the Bamianhe fault) constitute the boundary of the Dongying depression, and F5 (the Central fault zone), F6 (the Chenguanzhuang fault), F7 (the Binnan fault), and F8 (the Lijin fault) are the four main faults of the depression (modified from the Academy of Geological Sciences of the Shengli Oil Field). The top left inset is the base map of Dongying, Shandong province, China.
