Shear Wave Splitting Analysis Using SKS Phase

Anisotropy is an intrinsic part of our real Earth and the simplified assumption of an isotropic subsurface is generally not satisfied. Seismic anisotropy is mostly indicated by splitting of shear waves. We have worked on two earthquake events from the Andaman and Nicobar Islands and performed anisotropic correction for the two events by calculating the Fast Polarization Direction (FPD Ø) and delay time (ōt) with the help of SKS phase. The results are found to be consistent for both the events which helps in understating the anisotropic character of the region.
