"Focal mechanisms of seismic sources in anisotropic media are more complicated than in\r\nisotropic media. Planar shear faulting produces pure double-couple (DC) mechanism in\r\nisotropy, but generally non-double-couple (non-DC) mechanism in anisotropy. The non-DC\r\nmechanism can comprise both the isotropic (ISO) and compensated linear vector dipole\r\n(CLVD) components. The amount of the ISO and CLVD components depends on strength\r\nand symmetry of anisotropy and on the orientation of faulting. Shear faulting in anisotropy\r\ngenerates a pure DC mechanism, provided that faulting is situated in symmetry planes of or-\r\nthorhombic or of higher anisotropy symmetries. The fault plane solution, i.e. the orientation\r\nof the fault normal and the slip direction, can be retrieved from the seismic moment tensor\r\nand from elastic parameters describing anisotropy at the source. Numerical modelling shows\r\nthat shear faulting in anisotropic rocks present in the Earth crust, the Earth mantle or in the\r\nsubduction zones can produce mostly mechanisms with the CLVD up to 30 per cent and with\r\nthe ISO up to 15 per cent. The fault plane solutions calculated under the assumption of isotropy\r\ntypically deviate from the true solutions by an angle of 5º to 10º."^^ . "2005-12-15" . . "161" . "2" . .
