AusArray: Toward updatable, high-resolution seismic velocity models of the Australian lithosphere

Since the 1990s multiple passive seismic experiments have been successfully carried out by academia to image the Australia lithosphere. Over this time new seismological imaging methods have evolved resulting in numerous models of the Australian lithosphere using body-wave tomography, surface wave data, ambient noise analysis, and full waveform inversions. Despite this advance benchmarking of these different models is hard to achieve as they are often based on different underlying datasets. To overcome this problem, the Australian government and academia have united around the Australian passive seismic Array project (AusArray) which aims to obtain a national half degree data coverage and an updateable 3D national velocity model which grows in resolution as data became available.
