Abstract:
The proliferation of seismic networks in Australia has laid the groundwork for improved probing of the continental crust. In this study, we develop a new crustal model of the Australian continent using a large dataset that consists of nearly 30 years (1992-2019) of continuous seismic recordings from over 1600 stations. This unprecedented dataset is further exploited with a recently developed ambient noise imaging workflow that enables integrating temporary seismic arrays deployed at different times. We compute two sets of noise correlation functions (NCFs) between 1) synchronous stations with the conventional ambient noise correlation (i.e., C1) and 2) asynchronous pairs with the high-order correlation technique (i.e., C2) based on correlational and convolutional types of source-receiver interferometry.
