Description: Rotational motions generated by 1) shallow local earthquakes, 2) generator of rotational seismic waves, are studied both theoretically and by analyzing of real measured data. For theoretical modeling the ray method (BEAM87 package) and the ADER-DG method are used. Measurements are carried out in selected localities of special interest. Passive measurements are planed in areas characterized by natural or induced seimoactivity (Nový Kostel in Western Bohemia, Ostaš in Eastern Bohemia, Provadia in Eastern Bulgaria). In all these localities the rotational sensor developed by the members of the proposing team will be applied. In the same time, small-aperture arrays, which are installed permanently at the sites, will be used to derive rotational motions in the independent way. In other two selected regions (Hluboká-fault and Hronov-Poříčí fault zones) a system of an active artificial source together with the new sensor will be used for prospecting purposes. The artificial source is represented by the newly developed generator of rotational seismic motions, which was patented last year.
