Furthermore, specific features of such seismic sources cause that the ground effects of these events do not follow ground motion propagation rules worked out from observations of tectonic earthquakes. In particular, these ground effects depend on source directivity and path and site properties much stronger than the ground motion due to tectonic earthquakes. Following, the ground motion prediction equation should be site-specific and should take into account source mechanism and space-time clustering of sources. We present here new ground motion prediction equations, relevant for mining seismic activity in underground copper mines in Legnica-Glogow Copper District in Poland which have been developed taking into account the above considerations. The ground motion database, comprising 4533 signals, makes it possible to split ground motion prediction equations into classes, linked to similar source mechanisms or linked to similar locations. It has turned out that the normal and odd faulting events induce in general stronger motion than the thrust faulting and non-DC events. Also the membership of seismic sources to particular clusters of seismicity has proved to discriminate significantly the resultant ground motion amplitudes. This effect seems to be related to mining conditions.
