Some Aspects of L sub g and P sub g Propagation (Some Aspects of Lg and Pg Propagation)
Abstract
L sub g and P sub g (P) wavetrains consist of S and P waves trapped in the continental crust. The modal structure of these waves can be approximated from ray-tracing and Brune's (1964) constructive interference criteria for normal modes. Ray theory arguments show that the modes involved in L sub g and P sub g propagation are extremely sensitive to internal random inhomogeneities in the crust and small deviations of the free surface or the Moho from plane parallel surfaces.
