Two sets of sensors were installed in the USCB in Poland to measure angular velocities and translational accelerations from seismic events induced by underground coal mining. In the period from December 2015 to November 2016, 503 seismic events were recorded with local magnitude M between 1.1 and 3.5. Analysis of measurement data for induced seismicity confirmed a strong linear correlation between peak ground acceleration of shear S-waves, PGA and peak ground motion of angular velocity, PRV. The observed correlation can be a result of previously observed coupling between the angular instantaneous velocity vector and the respective displacement vector at the ground surface. Three types of empirical equations for induced seismicity in Upper Silesia in Poland were developed to predict the peak rotational ground motion of the vertical (torsion), horizontal (rocking), and instantaneous 3D-xyz components. The prediction values of horizontal peak angular velocity ground motion indicate that for strong mining-induced seismic events in the USCB with a magnitude of M = 3.5, we can expect that the mean values of PRVH will reach 7.5 mrad/s in the epicentral area (r = 500 m) and with magnitude M = 4 respectively will reach 19.7 mrad/s. Such values of ground rotation may substantially contribute to the overall seismic response of civil infrastructure, particularly for tall buildings. The study of angular velocity ground motion is important not only from the cognitive point of view, but also from practical significance for assessing the seismic impact on very high buildings, chimneys and stability of slopes. date: 2020 date_type: published publication: Engineering Geology volume: 276 publisher: Elsevier Science pagerange: 105767 id_number: doi:10.1016/j.enggeo.2020.105767 issn: 0013-7952 official_url: https://doi.org/10.1016/j.enggeo.2020.105767 access_IS-EPOS: limited owner: Publisher acknowledgments2: EPOS-PL_project citation: Mutke, Grzegorz and Lurka, Adam and Zembaty, Zbigniew (2020) Prediction of rotational ground motion for mining-induced seismicity – Case study from Upper Silesian Coal Basin, Poland.
