Abstract
The anomalous spatial oscillations of stacking velocity due to local inhomogeneities have been studied over the last decade (e.g. Rocca and Toldi, 1982; Loinger, 1983), but only recently have they been exploited as a quantitative tool for measuring the variations of seismic wave propagation velocity in the Earth. Harlan (1989) introduced an algorithm for tomographic inversion of stacking velocity anomalies using reflected rays, which is tested in this paper for information on its advantages and lirnits.
