Australia’s landscapes and resources are shaped by processes deep within the Earth. But how do we see what lies beneath our feet? At Geoscience Australia, we use a technique called passive seismic imaging, which listens to natural vibrations of the Earth rather than creating artificial signals. By deploying AusArray, the largest network of seismic sensors ever installed in Australia, we are mapping the continent’s crust and mantle in unprecedented detail. These images reveal the hidden architecture of basins, faults, and deep lithospheric structures that shape Australia’s geology. The results not only help us understand how our continent formed and evolved but also provide vital information for resource exploration and hazard assessment. This work formed part of national initiatives such as Exploring for the Future and will continue under Resourcing Australia’s Prosperity, which will deliver cutting-edge science to support Australia’s long-term prosperity.
