End-to-End Modelling of Earthquake-Induced Polarisation Perturbations in Submarine Optical Fibres
arXiv:2608.11903
Abstract
We present an end-to-end model of earthquake-perturbed signal propagation in submarine fibres. Ground displacements are converted to fibre strain via ocean pressure, and injected into a split-step model. Our model shows good qualitative alignment with measurements from the Curie cable during the 2020 Oaxaca earthquake.
