First-order P-wave ray synthetic seismograms in inhomogeneous, weakly anisotropic, layered media

Ivan Psencik & Veronique Farra


The first-order ray tracing (FORT) and dynamic ray tracing (FODRT) for P waves propagating in inhomogeneous, weakly anisotropic media are extended from smooth to layered media. All the basic formulae necessary for the transformation of FORT and FODRT quantities at the points of reflection/transmission are given. Accuracy of results is tested by comparison of approximate results with results obtained from a standard ray tracer.
