Home / DAS fiber optic earthquake sensing
Distributed Acoustic Sensing (DAS) has emerged as a groundbreaking technology in seismology, transforming fiber-optic cables into dense, cost-effective seismic monitoring arrays. DAS makes use of Rayleigh backscattering to detect and measure dynamic strain and vibrations over. As the seismological community embraces fiber optic distributed acoustic sensing (DAS), DAS arrays are becoming a logical, scalable option to obtain strain and ground-motion data for which the installation of seismometers is not easy or cheap, such as in dense off- shore arrays. It can change the way we measure a variety of signals, from ground motion to animal sounds, in real time. The National Seismic Network is working on the use of fibre optic cables to detect earthquakes and tsunamis in real time, study the structure of the shallow crust, and explore other potential applications of interest in the field of seismology.
