Description:

The article presents an attempt at using synthetic aperture radar interferometry to determine surface displacement in a region affected by a strong earthquake induced by underground mining operations. It was assumed that the satellite radar data obtained from the Sentinel 1A/B satellites may be used to monitor induced seismicity, i.e. mining tremors. Such seismic activity is observed at much shallower depths, and the surface area affected by such activity is much more limited than in the case of natural seismic events. Research was performed in a region located in the southwest part of Poland, where copper ore is extracted using underground methods. The geological structure of the selected area increases the likelihood of induced seismic events. Moreover, the area is one of the most seismically active regions in this part of Europe. The tremor analysed in this paper occurred on November 29, 2016, and had a magnitude of Mw4.2. Calculations showed that the seismic event resulted in the creation of a 2.7 km x 2.5 km subsidence basin. The paper demonstrates that it is possible to use data provided by the Sentinel 1A/B satellites to detect surface displacements caused by a mining tremor.
