Lateral Heterogeneity and Azimuthal Anisotropy of the Upper Mantle: Love and Rayleigh Waves 100-250 s
The lateral heterogeneity and apparent anisotropy of the upper mantle are studied by measuring Rayleigh and Love wave phase velocities in the period range 100-250 s. Spherical harmonic descriptions of the lateral heterogeneity are obtained for order and degree up to 1 = m = 10. Slow regions are evident at the East Pacific Rise, northeast Africa, Tibet, Tasman Sea, southwestern North America, an...
متن کاملAnisotropy induced dispersion behaviors of Rayleigh waves
Surface wave analysis is sometimes used in engineering investigations to obtain ground stiffness profiles by inversed modeling of dispersion velocities. Since dispersion data may be polarized due to material anisotropy, a thorough understanding of the dispersion property is necessary for the accurate reconstruction of inversion models. Based on the general constitutive relation of stress and st...

15 صفحه اولUpper crustal azimuthal anisotropy across the contiguous U.S. determined by Rayleigh wave ellipticity
Constraints on upper crustal seismic anisotropy provide insight into the local stress orientation and structural fabric, but such constraints are scarce except in areas with dense recordings of local seismicity. We investigate directionally dependent Rayleigh wave ellipticity, or Rayleigh wave H/V (horizontal to vertical) amplitude ratios, between 8 and 20 s period across USArray to infer azimu...
