OIT and Earth Sciences Department Test Distributed Acoustic Sensing on SMU Campus Dark Fibers

With Special Reporting from Chris Hayward, Department of Earth Sciences

 In the past several months, SMU’s Earth Sciences Department and SMU’s Office of Information Technology (OIT) networking have collaborated to test a new fiber optic interrogator that can measure tiny strains, the result of seismic noise from traffic, along with up to 100km of fiber optic cable. This technique is called Distributed Acoustic Sensing (or DAS). The first round of testing, which started just before the beginning of the Fall 2023 semester, viewed changes in the seismic noise as a result of students returning to campus and of the seismic noise generated as a result of the semester’s first football game.
