Seismic tomography using signal and noise: A new window into deep Earth

This project will image the lithosphere beneath southeast Australia in unprecedented detail by exploiting a unique repository of seismic data collected from over 400 instruments. In a break from tradition, every facet of the seismic record, including ambient noise data and various components of the earthquake wavetrain, will be combined via tomographic analysis. These first complete images of the deep structure beneath southeast Australia will play an important role in unravelling the tectonic evolution of the region. Major theoretical developments in ambient noise imaging and joint inversion methodology also form a core component of the proposal.
