Ground subsidence that occurred in an abandoned coal mining area, Gaeun Korea, is observed by using 25 JERS-1 SAR interferograms from November 1992 to October 1998. We estimate the subsidence on a subset of image corresponding to point-wise permanent scatterers by exploiting a 6-year temporal series of interferometric phases. The SAR measured subsidence rate represents only an average subsidence rate during a period of image acquisition, and complex nonlinear displacements such as an abrupt collapse are excluded. The obtained results are compared with the degree of crack levels obtained by field survey in 1997. The mean line-of-sight subsidence rate was 0.61 cm/yr in the area where the crack level was the most severe, and the largest radar measured subsidence was 11.2 cm. The degree of crack level correlates closely with ground subsidence. A two-dimensional subsidence map is also presented and generally complied with crack levels measured by field surveys.
