Interferometric Synthetic Aperture Radar (InSAR) is an effective tool to detect and measure the amount of surface deformation caused by earthquake, volcanic activity, landslide, land subsidence and others. In this paper, the authors propose the methods of phase filtering and atmospheric correction for the measurement of local deformation. Next, we apply InSAR technique using JERS-1/SAR data to Zonguldak coalfield in Republic of Turkey and verify the accuracy of measurement using GPS data and existing documents.<BR>The Zonguldak coalfield is developing in the seaboard of the Black Sea where is approximately 240 km away eastward from Istanbul. This underground coal mine produces three million tons in each year since it has opened in 1848. Recently topographic deformations are remarkable to affect roads, houses and others infrastructures. Because the whole damage has not been grasped, we tried to measure the amount of surface deformation by InSAR (May-September, 1995: 132 days). As a result, small areas with high phase gradient are detected over the mining tunnels, and the maximum topographic deformation was approximately 200mm in slant-range direction for 4.5 months. In addition, the result of measurement by InSAR accorded with that by GPS measurement within 8mm.
