  1. Each basin represents the geologic structural basin in the deforming area. Period of the largest gradient of subsidence/uplift, magnitude of maximum cumulative deformation for 2.5 years, and the size of the largest spatial deformation in a region was presented. The cause of deformation was inferred through comparison of the observed deformation, oil/gas production, the volume of the injected fluid, and the geologic characteristics.
