Geophysical phenomena and associated hazards unfold over various scales, from a few kilometers near faults or eruptive fissures to thousands of kilometers across ocean basins. The advent of fiber sensing technologies like Distributed Acoustic Sensing (DAS) and trans-oceanic long-range sensing has revolutionized the deployment of dense seismic arrays on land, ocean floors, and in volcanic regions. These technologies' broad reach and continuous monitoring capabilities enable the study of geophysical processes across multiple spatial and temporal scales. In my presentation, I will provide recent case studies where fiber sensing has enhanced our understanding of earthquakes, volcanic activities, and tsunami, and I will discuss their growing potential in early warning systems.
