“Sensitive seismic sensors based on microwave frequency fiber interferometry in commercially deployed cables”.

In this work, research collaboration between members of University of West Attica (Dept. Informatics and Computer Engineering, Dept. Electrical and Electronics Engineering), University of Thessalia (Dept. Physics), National Observatory of Athens (Institute of Geodynamics), ETH Zurich (Dept. Earth Sciences) University of the Aegean (Dept. Information and Communication Systems Engineering) and Hellenic Telecommunications Organization S.A. (OTE) present a novel sensing technique which relies on the dissemination of a stable microwave frequency along optical fibers in a closed loop configuration, thereby forming an interferometer that is sensitive to deformation. The proposed technique (MFFI) was tested in real life conditions and demonstrated its sensitivity to deformation induced by moderate-to-large earthquakes from either local or regional epicenters. Furthermore MFFI signals are compared to signals recorded by accelerometers of the National Observatory of Athens, Institute of Geodynamics National Seismic Network and by a commercially available DAS (Distributed Acoustic Sensing) interrogator operating in parallel at the same location provided by OTE. Remarkable agreement in dynamical behavior and strain rate estimation is achieved and demonstrated enabling MFFI as a novel technique in the field of fiber seismometers offering critical advantages with respect to implementation cost, maximum range and simplicity.
