Description	Contrary to natural earthquakes, where the features of the geological environ without void spaces and the character of loading naturally favor shear slip, in foci of seismic events induced by man-made activities there is a physically based reason for occurence of non-shear processes. Especially in mines, the existence of mined-out cavities enables implosive events which are improbable among natural earthquakes. In particular, great depth of excavation typically occurring in gold ore mining results in extreme loading of mine structures underground. High stress concentrations cause collapsing of excavated cavities, which is reflected by specific non-double-couple mechanisms. Apart from mining tremors, natural earthquakes of a tectonic origin may occur in the area where mining activity takes place.
