This article gives two analytical expressions of the displacement in a flat structure: one based on Cagniard's method for simpler cases, the other using a Fourier integral for more general cases. The numerical experiments aimed to check the methods b

The paper reviews the theoretical basis and the historical background of the Fourier-Bessel representation of the solution to seismic problems in layered media. The paper shows how to incorporate point sources into the process based on integrating an

Two finite‐difference schemes for solving the elastic wave equation in heterogeneous two‐dimensional media are implemented on a vector computer. A modified Lax‐Wendroff scheme that is second‐order accurate both in time and space and is a vers

Computations have been performed using an improper ω — k double integral representing the response to an SH pulse generated by a line source, acting in a model consisting of two homogeneous isotropic elastic or linear viscoelastic half-spaces sepa

In the last few years we started a project of building computer programs for “exact” synthetic seismograms, i.e. that can be calculated with a given accuracy for all the wanted time values. In other words, we don’t make any approximations based

The Cagniard method for obtaining the inverse Laplace transform of integrals, used when solving wave-propagation problems by generalized rays, was meant originally for simple cases of point-sources with a step-function time-dependence and simple stru

Exact synthetic seismograms are obtained for a simple layered elastic half‐space due to a buried point force and a point torque. Two models, similar to those encountered in seismic exploration of sedimentary basins, are examined in detail. The seis
