   It is necessary for full description of the ground vibration, in addition to three translational components and strain, to consider also three rotational components [e.g., 1, 6]. Traditionally, only the translational components of the earthquake ground vibration and structural response have been recorded. Classical Russian pendulum seismometer S-5-S was modified for recording of the rotational components of ground motion [3]. This seismometer was used for mining induced seismic events monitoring in the Karviná region. Together, classical translation vibrations were recorded [2]. Measurement in near-source area is necessary because rotational components are quickly attenuated. Our first records of rotational component were obtained during the experimental seismic monitoring in 2010 and 2011 that confirmed rotational component existence also for the mining induced seismic events.
   The values of ground rotational motion (Rot) around the vertical axis recorded in the seismic station at Doubrava village (Karviná region) exceeded value of 1 mrad.s-1. Numerical study of measured rotational component attributes is presented in this paper.
