| Abstract: | During development of theoretical methods to compute synthetic seismograms, a new type of wave called S*-wave was discovered by Hron and Mikhailenko. This wave propagates with the shear-wave velocity and can be interpreted as a non-geometrical wave arrival with large amplitudes strongly depending on the depth of a pure P-point source. In this first experimental verification of the existence of S*-waves by means of two-dimensional model-seismics it is demonstrated that: 1. the S*-wave exists and depends on the source distance from the free surface; 2. the S*-wave is generated as an ordinary shear wave on the free surface at the point located directly above the P-source, as illustrated in the synthetic seismograms. The measured seismograms agree remarkably well with the computed ones. |
