Measuring the seismic pulse of the Earth using fibre optics

Seismic observations are critical for understanding many aspects of Earth processes and structure, however these observations are limited by the cost and nature of deploying traditional seismometers. Utilising fibre-optic cables can greatly increase the number of observations and decrease the cost of the experiments. Results from this project will provide technological advances that will change passive sensing capabilities using existing infrastructure. The economic, environmental and social benefits include: Contributions to resource exploration and recovery Monitor environmental changes in the subsurface and determining aquifer properties Provide hazard assessment by determining earthquake occurrence and location Generate high-resolution Earth models that are essential for estimating ground shaking, locating faults and studying environmental processes Contribute to global security via nuclear test monitoring Applicable for use of existing, extensive telecommu
