The phenomenon of induced seismicity is caused by anthropogenic activity such as: underground and opencast mining, extraction of conventional and unconventional hydrocarbons, construction of water reservoirs and production of geothermal energy. In recent years, interest in induced seismicity increased due to the fact that it causes increasingly stronger earthquakes, even above 4 on the Richter scale. Thus, it poses a threat to people, technical and urban infrastructure. This study analyzed the seismic event of M = 4.6, which occurred on the 15 September 2018 in the Rudna copper mine area in SW Poland. For this purpose, Sentinel 1 satellite data and DInSAR processing method were used to determine the ground movement values in the satellite line of sight. Based on the results for four image pairs, the area disturbed by the seismic event was determined. The maximum values of subsidence ranged from -65 mm to -75 mm depending on the analysed dataset and the area of deformation was determined at approx. 4 km sq. The results indicate the usefulness of the adopted method to determine ground deformation caused by induced seismicity in an underground mining area.
