Distributed fiber-optic sensing (DFOS), particularly distributed acoustic sensing (DAS), is revolutionizing subsurface imaging and rapidly transforming geohazard monitoring. Leveraging large-scale access to telecommunication (dark) fibers, DFOS offers an unprecedented opportunity to monitor dynamic Earth processes with high spatial and temporal resolution. This session invites contributions showcasing advancements addressing challenges in imaging, monitoring, and interpreting DFOS datasets for near-surface geoscience studies focused on subsurface characterization and geohazard assessment (e.g., landslide, volcanic activity, induced seismicity). Applications include, but are not limited to, geotechnical engineering (e.g., infrastructure monitoring), environmental geology (e.g., permafrost, glaciers), hydrology (e.g., fluid flow characterization), and marine sciences (e.g., submarine cable-based sensing). We welcome topics including sensing innovations, dense array processing techniques, realtime processing, and cable deployment strategies, and case studies in geotechnical and environmental applications. This session aims to highlight scientific and engineering perspectives, emphasizing how fiber sensing is advancing near-surface geosciences through scalable, high-resolution insights into Earth processes.
