“…In this way, the strain field induced by natural processes (e.g., earthquakes) and urban activities (e.g., moving vehicles, construction, pumps) acting on the fiber coupled to the Earth can be sampled at a meter‐scale spatial resolution over tens of linear fiber kilometers. Notably, DAS technology has proven effective on existing and growing “dark fiber” telecommunication infrastructure for earthquake monitoring (Biondi et al., 2021), infrastructure monitoring (Liu, Yuan, Luo, et al., 2023; Yuan et al., 2021), and near‐surface imaging (Fang et al., 2020; E. R. Martin, Castillo, et al., 2017; Mjehovich et al., 2023), significantly reducing installation cost. Furthermore, by incorporating state‐of‐the‐art interrogators, such as OptaSense QuantX (Optasense, a Luna company, 2022), DAS can record full waveform signals over distances up to 50 km, with a granular 1 m channel spacing, which makes DAS promising for continuous city‐wide sensing.…”
