Grid Setting in Seismic Tomography for Elliptical Anisotropic Media

n this study, we discuss the adjustment of grid definition in relation to seismic tomography in the case of elliptical anisotropic media. To optimize cell numbers and dimensions, the results of a staggered grid method are used to define an adjusted grid as a starting model for inversion. This procedure can be iter- ated, although improvements are not assured. First, two synthetic models with growing level of complexity are performed. Next, data from a previously conducted field survey are analyzed by intro- ducing staggered grids. Finally, the results are compared with the previous results. The adjusted grid represents a technique that can be used to obtain an effective way of discretizing the model domain for further inversion, which often improves results for the velocity model. These conclusions can also be applied to isotropic media, as described in this study.
