Distributed Acoustic Sensing (DAS) has been increasingly utilized to build relationships in complex geophysics environments by utilizing continuous measurement along fiber optic cables with high spatial resolution and a frequency response of up to 10 KHz. The advent of fiber optic technology in geophysics exploration has grown in its use in the exploration, production, and monitoring of subsurface environments, revolutionizing the way data are gathered and interpreted critically to speed up decision-making and reduce expense and time. The "Fiber Optic Cable Use for Seafloor" project (FOCUS) has demonstrated how we can use existing fiber-optic cables to detect small movements on the seafloor caused by tectonic faults. Our aim is to improve understanding of fault activity, and therefore of possible earthquakes. Researchers use DAS to collect real-time, high-resolution observations without disrupting the.
