I have presented a finite-difference method of traveltime computations, based on the linearized eikonal equation. Preliminary numerical experiments show that the method is as simple and robust as can be expected from the theory. The required assumption is that a reasonable estimate of the traveltime is available prior to linearization. Such an estimate may result from the computation in a different velocity model, with a different method (e.g., ray tracing), or by an analytic evaluation.
In the situations where the underlying assumption is valid, the linearized approach may allow us
