The Stanford Distributed Acoustic Sensing Array (SDASA)

Repurposing existing infrastructure as seismic arrays

I work with my advisor, Biondo Biondi, and OptaSense to run a fiber optic distributed acoustic sensing array in existing telecommunications conduits underneath the Stanford campus. Goals of the Stanford DAS Array-1 (SDASA-1) include evaluating such a system for: near surface monitoring with ambient seismic noise, active seismic surveys, and earthquake detection. Read a little about the earthquake detection aspects of the project in IEEE Spectrum.
