Abstract

<div><strong>Output type: </strong>Exploring for the Future Extended Abstract</div><div><br></div><div><strong>Short abstract: </strong>Passive seismic methods serve as versatile tools for probing Earth structure and facilitating new geological and geodynamic insight across vast areas. Tomographic velocity models derived from continental scale passive seismic data are becoming increasingly important in guiding resource exploration into prospective regions. While Australia has been leading this field our existing data coverage and quality is insufficient resulting in large uncertainties in continental scale models. With the aim of robustly constraining Australia’s lithospheric architecture the Exploring for the Future (EFTF) program began collection of a 2° (~220 km spaced) AusArray passive seismic data coverage. There are over 150 broad-band seismometer stations simultaneously deployed across Australia for a period of up to two years - a pioneering effort on a continental scale. The quality assurance/quality control (QA/QC) analysis and deployment approaches, refined during previous 0.5° (~55 km spaced) campaigns, were rigorously applied to prevent data errors or data loss. Advanced standard operating procedures and stakeholder engagement materials were developed and openly shared with broader professional communities to support similar activities, fostering the continued advancement of passive seismic methods in both industry and research. The resulting data will be shared via the eCat system in raw format, accompanied by a StationXML file that holds the QA/QC information. This file can be used to apply QA/QC results to raw waveforms, enabling their use in subsequent analysis and modelling endeavors. Insights from this survey will guide future higher resolution AusArray deployments. &nbsp;</div><div><br></div><div><strong>Citation: </strong>Gorbatov, A., Hejrani, B., Holzschuh, J., Zhao, J., Hassan, R., Cathro, D., Czarnota, K., Kuoni, J., Sweeney, M., Glowacki, J., Murdie, R., O'Donnel, J.P. & Haydon, S.J., 2024.
