Distributed sensing measures vibration around the world from Tonga volcano (Hifi)

Recent volcanic events in Tonga created an event which had extensive global reach. Hifi’s high fidelity distributed sensing (HDS) systems detected residual strain from the wave of ground movement. Some of these systems were located in western North America at a distance of over 10,000KM from Tonga. FOSA is looking into ways further collaboration through distributed fiber optic sensing can be done to assist in predictive measurements for geotechnical events.
