"Tensile earthquakes are earthquakes which combine shear and tensile motions on a\nfault during the rupture process. The geometry of faulting is described by four angles:\nstrike, dip, rake, and slope. The strike, dip, and rake define the orientation of the fault\nnormal and the tangential component of the dislocation vector along the fault. The slope\ndefines the deviation of the dislocation vector from the fault. The strike, dip, and rake\nare determined ambiguously from moment tensors similarly as for shear sources. The slope\nis determined uniquely and has the same value for both complementary solutions. The\nmoment tensors of tensile earthquakes are characterized by significant non-double-couple\n(non-DC) components comprising both the compensated linear vector dipole (CLVD)\nand the isotropic (ISO) components. In isotropic media, the CLVD and ISO percentages\nshould have the same sign and should depend linearly for earthquakes that occurred in the\nsame focal area. The direction of the linear function between the CLVD and ISO defines\nthe velocity ratio n P /n S in the focal area. The parameters of tensile earthquakes can be\nretrieved from their moment tensors. The procedure yields the angles describing the\ngeometry of faulting as well as the n P /n S ratio in the focal area. The accuracy of the n P /n S\nratio can be increased if a set of moment tensors of earthquakes that occurred in the same\nfocal area is analyzed. The calculation of the n P /n S ratio from moment tensors is an\nauspicious method which might find applications in tomography of the focal area or in\nmonitoring fluid flow during seismic activity. If the n P /n S ratio is found and well\nconstrained, the parameters of tensile earthquakes can be inverted directly from observed\ndata using a constrained nonlinear inversion. In this inversion, the parameter space can be\nlimited by fixing the n P /n S ratio or forcing the n P /n S ratio to lie within some physically\nreasonable limits."^^ . "2011-12-30" . . "116" .
