Normal mode splitting due to inner core attenuation anisotropy

The Earth's inner core displays transverse velocity anisotropy with cylindrical symmetry, which causes the anomalous zonal splitting of inner core sensitive normal modes. In this paper, we extend existing theory for calculating normal mode splitting from models of cylindrical velocity anisotropy to include models of anelastic attenuation anisotropy. Furthermore, we derive the equations that can be used to rewrite the attenuation anisotropy parameters natural to normal mode considerations in terms of body wave attenuation anisotropy for compressional and shear waves
