the present paper studies the possibility of propagation of torsional surface waves in an inhomogeneous anisotropic layer lying between two heterogeneous half-spaces (upper and lower half-space). both the half-spaces are assumed to be under compressive initial stress. the study reveals that under the assumed conditions, a torsional surface wave propagates in the medium. the dispersion relation ...

The table of source phase differences between Rayle igh and Love waves which was described in Pa r t I and used in Pa r t 2 is presented in a concise form for the case of a surface focus.

We investigate long-period surface waves (T> 100 s) propagating across the Tibetan Plateau, based on the seismic records from a PASSCAL portable array and nearby Chinese Digital Seismic Network (CDSN) stations. Significant quasi-Love waveform anomalies, associated with fundamental Rayleigh-Love coupling, are consistently observed, suggesting that strong lateral gradients in azimuthal anisotropy...

S U M M A R Y We perform a comprehensive analysis of dynamic triggering around the Babaoshan and Huangzhuang-Gaoliying faults near Beijing, China. The triggered earthquakes are identified as impulsive seismic arrivals with clearP and S waves in 5 Hz high-pass-filtered three-component velocity seismograms during the passage of large amplitude body and surface waves of large teleseismic earthquak...

Elastic surface waves propagating at the interface between an isotropic substrate and a thin, transversely isotropic film are analyzed. The transverse isotropy is conferred by fibers lying parallel to the interface. A rigorous leading-order model of the thin-film/substrate interface is derived from the equations of three-dimensional elasticity for prestressed, transversely isotropic films havin...
