Distributed Acoustic Sensing - Brady Cox

Distributed Acoustic Sensing - Brady Cox

Author: Natural Hazards Engineering Research Infrastructure April 12, 2022 Duration: 11:15

Natural hazards engineers at the University of Texas are using fiber optic cable for subsurface and structural sensing. It’s called distributed acoustic sensing, or DAS, and it is much more efficient than traditional geophones or accelerometers. By sending laser light pulses through fiber optic cables — which are ultra-sensitive to light deflections — researchers can measure ground disturbances for up to 30 meters.

NHERI at UTexas recently presented a workshop on DAS technology, including a live demonstration of a levee in Blackhawk, Louisiana. View the workshop recordings here


The forces that shape our world aren't always gentle. Earthquakes, hurricanes, floods, and tornadoes are a reality of life on this planet, but the scale of their impact is something we can influence. DesignSafe Radio, from the Natural Hazards Engineering Research Infrastructure team, delves into the human ingenuity working to soften the blow of these events. This isn't just a theoretical discussion; it's a close look at the rigorous testing, data, and engineering research funded by the National Science Foundation that aims to protect communities. Each episode pulls back the curtain on how scientists and engineers are learning from past disasters to fortify our future. You'll hear conversations about the tools and methods transforming how we understand structural resilience, offering a tangible sense of how research translates into real-world safety. The goal is straightforward: to ensure the next natural hazard doesn't escalate into a catastrophe for families and neighborhoods. Tune into this podcast for a grounded perspective on the intersection of science, education, and practical solutions, where complex research is made accessible and the focus remains firmly on building a more durable society.
