In this paper the methods for representation theorem coupling of finite-element or finite difference calculations and propagator matrix method calculations (Harkrider) are developed. The validity and accuracy of the resulting hybrid method are demonstrated. The resulting hybrid technique can be used to study the propagation of any phase that can be represented in terms of an SH mode sum seismog...

The D″ region consists of many different structures on length-scales and here we test whether an inhomogeneous scattering could potentially explain two these seismic observables, namely PKP precursors, which are generated by near the core-mantle boundary, reflections a discontinuity in lowermost mantle. focus this study is modeling precursors lower mantle reflections. Testing heterogeneity mode...

Abstract The elastodynamic half-space Green’s function has been the subject of research for more than a century since Lamb’s classical solution. Here, we revisit problem and present new closed analytical solution, in frequency domain, based upon Principle Equipartition (EQP) Energy. This principle asserts that imaginary parts tensor components equal average cross-correlations fields generated b...

We discuss three stacking deconvolution techniques for enhancing signal of earth structure contained in the seismograms of teleseismic body waves recorded by a seismometer array. The goal of the deconvolution is to remove from the seismograms the complications due to the source. For three-component data the removal of the source can be efficiently achieved by deconvolving one component from ano...
