Newly established seismic station at Pražmo represents the easternmost station at the territory of the Czech Republic. It is supposed that this station will contribute to detection of mining induced events from the Upper Silesian Coal Basin and to local tectonic events in the eastern part of Moravian-Silesian region. Seismological recordings obtained at PRAZ station during six months of continual monitoring were analysed not only from the seismological point of view, but the local geology effect has been considered as well. Achieved results proved that the PRAZ station contributes especially to the detection of mining induced events from the Ostrava-Karviná Coal Basin. Evaluation of local site effect by spectral ratio methods confirmed low amplification at an investigated place due to first meters of Quaternary sediments covering the sandstone bedrock. Performed detail analysis of mining-induced and local tectonic events proved that the PRAZ station provides good-quality data for the foci location.
