Sn-wave velocity structure of the uppermost mantle beneath the Australian continent

Wei, Zhi; Kennett, Brian; Sun, Weijia


We have extracted a data set of more than 5000 Sn traveltimes for source–station pairs within continental Australia, with 3-D source relocation using Pn arrivals to improve data consistency. We conduct tomographic inversion for S-wave-speed structure down to 100 km using the Fast Marching Tomography (FMTOMO) method for the whole Australian continent. We obtain a 3-D model with potential resolution of 3.0º × 3.0º. The new S-wave-speed model provides strong constraints on structure in a zone that...[Show more]
