The Upper Silesia Coal Basin (USCB) is characterised by a complicated geological structure, which is affected by the over 200-year hard coal mining. The hazards caused by the induced seismicity and ground subsidence are connected with the hard coal mining. The hazards arising from the formation of subsidence and induced seismicity-related troughs necessitate monitoring the USCB area. The availability of satellite data resulted in the development of novel methods, which can significantly affect the monitoring quality of an endangered area. Interferometric Synthetic Aperture Radar (InSAR) is a satellite based method that can be used to measure surface deformation. In Poland InSAR for mining monitoring was applied with success in Upper Silesian Coal Basin and Legnica-Głogów Copper Mining District. The Permanent Scatterer Interferometry technique (PSInSAR) is an upgrade of InSAR. This technique was developed to resolve problem of geometrical and temporal decorrelation. Furthermore, by using a large amount of data, atmospheric signal is estimated and corrected for. In this paper authors were used PSInSAR data technique covering the north-eastern part of the Upper Silesian Coal Basin with a surface area of approx. 1210 km2 were used in this work (Fig. 1.). The radar pictures were taken by the ERS-1, ERS-2 and ENVISAT satellites and cover a period of time of 1992 to 2003. In this work authors make an attempt to correlation between satellite data and epicentre of mining seismicity.
