Lesson No. 30: Reflection from a Dipping Interface—Three-Dimensional Problem—Applications
Published:January 01, 1959
We now proceed to a discussion of the general case of our problem. It will become evident that the general case, in fact, includes the special cases already discussed.
Under the conditions which we have imposed thus far, namely, that the medium is one of constant seismic velocity, bounded by the horizontal plane of the earth and a dipping reflecting plane, there is a fact of basic importance:
The sum of the squares of the travel-times of a reflection from a central shot point to any pair of diametrically opposite points is constant; that is, this sum is the same whatever be the azimuth of the line joining the two points.

Lessons in Seismic Computing
“An elementary text and problem book containing 44 lessons in seismology arranged for selection or combination to cover the normal 36-week course, or for condensation into an 18-week course. The lessons begin without assuming more than secondary school mathematics. An elementary knowledge of calculus is desirable, though not required, for the last half of the book.”
