- W2056055425 abstract "by a finite difference method. We show that this scheme can violate causality for moderate to large velocity contrasts (V,/V, > 1.4). As an alternative we present a scheme where the solution region progresses along an “expanding wavefront” rather than an “expanding square”, and thenfore honors causality. Our method appears to be stable and reasonably accurate for a variety of velocity models with moderate to large velocity contrasts. The penalty is a large increase in computational cost and programming effort." @default.
