Abstract
An improved method for modeling the velocity of seismic energy in subterranean rock layers is described. The velocity is assumed to vary such that the gradient of the velocity, that is, the direction of maximum change in the velocity, is at all times perpendicular to the interfaces between the rock layers. Improved methods of generating a representation of a subterranean structure of the earth are also disclosed.
