...)=G(r){\cdot}\mathrm{e}^{-{\pi}fr{/}Q{\beta}},\] \end{document} where f, r, β , and G ( r ) are frequency, hypocentral distance, mean shear-wave velocity, and the geometric spreading function, respectively. We constrain G ( r ) = 10/ r b , finding that the coefficients b and Q are both frequency...

...T. A. Mokhtar; R. B. Herrmann; D. R. Russell Abstract The shear velocity and Q (sub beta ) structure for the upper 1 km in different tectonic regions of the Arabian shield have been investigated using high-frequency vertical component records of Rayleigh waves (1-20 Hz), which were recorded...

..., which takes into account the departure of the primary active electromagnetic field from a plane wave form at the air-sea interface, is incorporated into the complex two-layer correction function Q m . A rescaling factor F brings H I into good agreement with H S in the depth regime where the beta...

..., ordered: Q (sub M(3)) [= (X (sub M(3A)) -X (sub M(3B)) )/(X (sub M(3A)) +X (sub M(3B)) )] is equal to 0.89, rather than to the value of 1.0 expected for the beta angle of this crystal. However, the refined M(3A) and M(3B) site-scattering values are compatible with complete order of Al at M(3A...

... with a 30-km crossover distance, coupled to an anelastic function exp(− ϖfr / [capital greek beta]Q ( f ), where: Q ( f ) = 180 f 0.42 . A body-wave geometric spreading, g ( r ) = r −1.0 , is used at short hypocentral distances ( r < 30 km), whereas g ( r ) = r −0.6 fits the attenuation of the spectral...
