Spherical divergence seismic
WebThis Demonstration shows the propagation of spherical elastic waves, commonly known as seismic waves, from a point source. Shown here are two types of seismic waves: pressure wave (P-wave) and shear wave (S-wave). The P-wave is longitudinal, and thus oscillates along the direction of the wave propagation, while the S-wave shakes perpendicular ... Web27. apr 2006 · Spherical divergence and absorption produce a general decrease in wave amplitude with increasing propagation distance in an isotropic medium (Sheriff 1975). In this article, we assume that the...

Because velocity increases with depth, ray path curvature causes the energy density to fall off even more rapidly. The rate of … WebAGC is used in data processing to improve the visibility of seismic data in which attenuation or spherical divergence has caused amplitude decay ( Figure 5.3 ).
