Analysis and compensation of the effects of S-wave splitting in azimuthally anisotropic media, which has become a routine step in the processing of S-waves in multicomponent data, often assumes an earth model made of horizontally transverse isotropic layers. In this respect, in 2016, we proposed to invert interval values of splitting intensity that, in comparison with the state-of-the-art methods, is a robust measurement in cases of lateral velocity variations and structural dips and is commutative, which means that it avoids the time-consuming layer-stripping procedure. In this work, we show that splitting intensity enables characterization of tilted transverse isotropic and tilted orthorhombic media, opening new opportunities for anisotropic model building.
