“…These apparatuses provide digital records of measured signals in the frequency range of 0.5-30 Hz and sampling frequency of 100 Hz. Measurement of rotational component of vibrations, using newly developed S-5-SR sensor, was also performed in Orlová and Doubrava localities (Knejzlík et al 2012, Kaláb et al 2013, Lyubushin et al 2015. Results from seismological monitoring together with geotechnical studies are used also for evaluation of seismic loading of structures, e.g., Kaláb and Lednická (2012).…”

The Karviná region is well known as an area with an intensive mining induced seismicity. The local geological pattern, especially subsurface sedimentary layers, belongs to one of the most important factors that influence the amplification of seismic effect on the surface. In order to investigate the amplification effect, there are used methods of spectral ratio that enable to analyse records of vibrations. In the present study, two methods, signed as SSR (standard spectral ratio) and HVSR (horizontal to vertical spectral ratio), were used for the site effect evaluation. The analysis was performed in the populated Doubrava locality where high seismic loading on the surface due to mining induced seismicity is documented.

“…The precise balance is realized using two independent balancing weights mounted on perpendicular set-screws. Routine of precise balancing is described in (Knejzlík et al, 2010). It means that main measuring element is very well balanced two-armed lever.…”

“…Main dynamic parameters of the modified rotational sensor, e.g., its natural period and its damping were controlled electronically by feedback of angular displacement and angular velocity, both conducted to the damping transducer coil. For detailed information about the modification of S-5-S see papers by Knejzlík et al (2011Knejzlík et al ( , 2012.…”

“…The Russian pendulum seismometer S-5-S appeared as suitable for modification for the recording of rotational components of ground motion around the vertical or horizontal axis. This S-5-S modification was realized by specialists of the Institute of Geonics, ASCR, in 2010 (Knejzlík et al, 2012).…”

Classical Russian pendulum seismometer S-5-S was modified for recording of the rotational components of ground motion around the vertical or horizontal axes; the modified sensor is denoted here as S-5-SR. Experimental field testing of the S-5-SR sensor started in December 2010 in the Karvina coal region that is known as an area of intensive mining induced seismicity. First seismic station was installed in Doubrava village characterized by thick sedimentary layers. Next seismic station was installed in Orlova village, in different local geological conditions, i.e. in region without sedimentary layers. More than 200 mining induced seismic events were recorded on each seismic station during the period of six months of seismic monitoring. The recorded wave patterns confirm the existence of rotational ground motion components in this region; the strongest recorded value of this component exceeded 1 mrad.s-1. Analysis of the obtained records is presented in this paper.
