To estimate the amount of error in lateral positioning due to over- or under-migration at the B-fault, we use the approximate depth z and dip of the fault given by 2 km and 45º, respectively (see supplementary Fig. 1B). From equation (6), a ±5% error in migration velocity results in a lateral posi ...

Surface wave inversion
Inversion is the set of methods used to infer properties through physical measurements. Surface wave inversion is the method by which elastic properties, density, and thickness of layers in the subsurface are attained through analysis of surface wavedispersion. The entire inversion process requires the gathering of seismic data, the creation of dispersion curves, and finally the inference of subsurface properties.
