| Scope |
Fiber optic sensing is revolutionizing Earth science by transforming telecommunication cables into dense, multipurpose sensor arrays. Techniques such as Distributed Acoustic/Strain Sensing (DAS/DSS) and Distributed Temperature Sensing (DTS) provide unprecedented spatial resolution for monitoring vibration, strain, and temperature, enabling high-fidelity observations that surpass conventional point measurements in seismology, geodesy, and volcanology. However, significant challenges remain in the integrated analysis of this novel strain data with traditional seismic (velocity/acceleration) and geodetic measurements, as well as in the technical difficulty of maintaining a high signal-to-noise ratio over long-distance cables. This session invites contributions that address such challenges and advance the use of fiber optic sensing. We seek presentations on innovative observation strategies for both on-shore and off-shore environments; novel data analysis methods, including machine learning for handling massive datasets; and compelling case studies that deepen our understanding of earthquakes, volcanoes, and tectonics. The goal is to foster collaboration to overcome current hurdles and pioneer the next generation of integrated seismic and geodetic observation networks, thereby fully unlocking the potential of fiber optic technologies to reveal new insights into Earth science.
