Description

Lighting Up Dark Fibre for Seismic Imaging. Distributed acoustic sensing (DAS) is a newly emerging passive seismic technique that converts telecommunication fibre-optic cables (dark fibres) into thousands of individual ground motion sensors. This project aims to harness DAS and the big data arising from it to develop unprecedented high-resolution images of the Earth’s structure, detect micro-seismicity, and thereby relate geological observations to Earth processes. Outcomes of this powerful technique include fine-scale seismic imaging of the Earth’s subsurface as the best proxy for geological processes and geochemistry. Benefits include transforming exploration of mineral resources, water, changes in subsurface structure, as well as geohazard assessments for Australia and worldwide. Scheme: ARC Future Fellowships.
