A new, highly sensitive fiber optic gyroscope can enhance risk assessment and early warning signs for seismic hotspots. With fibers precisely wound around an aluminum spool, the gyroscope, based on the Sagnac effect, enables real-time monitoring of ground rotations caused by earthquakes. The additional information is critical to detecting changes in volcanic dynamics. Find the full press release in our newsroom!
