The ray theory belongs to the methods most frequently used in seismology and seismic
exploration for forward and inverse modelling of high-frequency seismic body waves. In …

Structural geologists are well aware of the fact that isotropic rocks are quite exceptional in
nature. Whicheverorigin, sedimentary, metamorphicormagmatic, rocks are shaped with a …

We derive the explicit analytical expressions of the phase velocities of the three bulk waves
(qP, gS 1 and qS 2) propagating in an arbitrary direction in a homogeneous strongly …

The parameterization of anisotropic models is very important when focusing on specific
signatures of seismic waves and reducing the parameter crosstalk involved in inverting …

Singularities often cause trouble in tracing rays in inhomogeneous anisotropic media. The
ray‐tracing algorithms can break down in the vicinity of the singularities because the …

An approximate expression of the eikonal equation and the polarization vector may be
obtained in weakly anisotropic media from first-order perturbation theory. The advantage of …

We propose approximate ray-tracing equations for qP-waves propagating in smooth,
inhomogeneous, weakly anisotropic media. For their derivation, we use perturbation theory …

Using ray perturbation theory, a linear relationship is derived that describes the first-order
perturbation in slowness vectors due to elastic parameter and interface perturbations as well …

An explicit analytical formula for the complete elastodynamic Green tensor for homogeneous
unbounded weak transversely isotropic media is presented. The formula was derived by …
