Modification of anisotropy analysis in Moho using converted Ps phase

Seismic velocity changes and shear wave anisotropy analysis can provide insights into deep structures. In multi-layered structures, cosine moveout pattern of radial component is observed for converted Ps phase. The method to calculate anisotropy parameters in layered structures has been developed by Ruempker et al. (2014). Some seismic stations do not have enough coverage in some azimuths, and we can split parameters (φ, δt) by fitting the best curve on Ps arrivals using the grid-search method. In this study, using synthetic data, the effect of the azimuth coverage is investigated and the sensibility of the results is also examined.
