Catastrophe optics provides insights into the structure of the caustics produced by seismic events. Two examples are given. The first is the caustic formed on the surface of the Earth between 10° and 30° from the event by P rays that have reached the transition zone of the mantle. This is organized by one or more approximately ...

WebSummary. Seismic ray theory is analogous to optical ray theory and has been applied for over 100 years to interpret seismic data. It continues to be used extensively today, owing … Webequations for the amplitudes of the ray-theory elastodynamic Green function is lat-erally varying layered structures are derived. Great attention is also devoted to the ray-series solutions, both in the frequency and the time domain. The seismological applications of higher-order terms of the ray series are discussed.

Web9781560801481. Store. SEG Online Store. The concept of a ray is extremely useful. Rays are curves drawn in space, and they correspond to the directions of flow of propagated energy. In other word, rays are flow lines. Being flow lines, rays cannot cross each other. As such, the ray is a mathematical device rather than a physical entity.
