This is a temporary broadband seismic array along the northwestern coastal region of Western Australia, operated by Macquarie University, Geological Survey of Western Australia, and the Institute of Geology and Geophysics, Chinese Academy of Sciences. The target is the lithospheric structure of this part of Australia, whose formation and evolution history spans from ~3.2 Ga to very recent during the Neo-Tethys ocean opening ~140 Ma.
There are 3 phases of the deployments of several linear arrays. The first two phases are already finished, which is composed of 60 sites. The 3rd phase is going to be deployed in the second half of 2020, and will last for a year. This phase will be composed of 40 sites.
