Paper Abstract

Conventional finite difference eikonal solvers produce only the first arrival time. However suitable solvers (of sufficiently high order of accuracy) may be extended via Fermat's principle to yield a simple algorithm which computes all travel times to each subsurface point, with cost on the same order as that of a first arrival solver.
