Fiber-optic sensing technologies, particularly Distributed Acoustic Sensing (DAS), are transforming geophysics by enabling dense, long-range, long-duration, and cost-effective sensing across diverse environments. We invite submissions on earthquake detection and early warning, source characterization, subsurface imaging, environmental monitoring, and other applications in urban areas, volcanic systems, glaciers, permafrost, underwater, boreholes, and potential planetary environments. Topics may range from high-frequency signals from marine mammals and vessel activity to lower-frequency phenomena such as internal waves, tides, tsunamis, and quasi-static deformations caused by landslides and magma intrusions. We also welcome energy and security applications, including underground explosions, geothermal production, hydrocarbon extraction, carbon sequestration, and infrastructure monitoring. Contributions on the scalability, including real-time processing, compression, and end-to-end workflows supporting large-volume data are encouraged. While DAS is the central focus of this session, we welcome exploratory work on alternative fiber-optic sensing technologies, such as long-range systems for subsea cables, polarization sensing, or transmission-based systems.
