Abstract: Abstract. The widespread availability of broad-band digital seismic data makes it possible to measure traveltime anomalies by cross-correlation with spherical-earth synthetic seismograms. Finite-frequency diffraction effects render such measurements sensitive to wave-speed perturbations off of the infinite-frequency geometrical ray path. We show, by consideration of a simple 2-D example, that the Born approximation provides an excellent description of these off-path sensitivity effects, in the absence of caus…
