Decomposition and Properties of the Traveltime Sensitivity Kernels in Transversely Isotropic Elastic Media

This study discusses the properties and decompositions of traveltime sensitivity kernels in elastic isotopic transversely isotropic media. Analytical solutions homogeneous media are derived help better understand their properties. One key component is kernel phase function which determines frequency components kernels, geometrical setting Fresnel zones, resolving ability for velocity inversion. For purpose exploration seismology, finite-frequency inversion expressed terms Thomsen’s anisotropic parameters. The can be decomposed into summation constructed by symmetry direction correction due to presence anisotropy. Sensitivity computed from different types acquisitions contain information We compare using finite-difference with those dynamic ray tracing. conclude that full wave numerical method able provide high-resolution form basis 3D
