Structure and evolution of the Australian plate and underlying upper mantle from waveform tomography with massive data sets
We present a new S-wave velocity tomographic model of the upper mantle beneath the
Australian Plate and its boundaries that we call Aus22. It includes azimuthal anisotropy and …
