[SIT25-P03] Radial anisotropy as "bodywave-surface wave discrepancy"
Song and Kawakatsu (2012) has demonstrated how bodywaves that enter the LAS with different incident angles can be used to constrain asthenospheric anisotropy. Also the reflection/conversion efficiency at the G-discontinuity depends on the fifth parameter in a peculiar way. Thus bodywaves can provide additional information about radial anisotropy of the LAS, and it is possible to view radial anisotropy as "bodywave-surface wave discrepancy" through the new parameter, \eta_k. Lateral change of the strong asthenospheric anisotropy may be due to this effect.
