TL;DR: The use of fiber-optic cable for measurement of ground motion is a relatively recent development in distributed acoustic sensing (DAS) as mentioned in this paper, with the fiber cable itself as a sensor.

TL;DR: The Frio experiment in Texas was undertaken to provide answers to these questions as discussed by the authors, where one thousand six hundred metric tons of CO2 were injected into the Frio Formation, which underlies large areas of the United States Gulf Coast.

TL;DR: This study reports the first end-to-end study of time-lapse VS imaging that uses traffic noise continuously recorded on linear DAS arrays over a three-week period, demonstrating the efficacy of near-surface seismic monitoring using DAS-recorded ambient noise.

TL;DR: One of the first case studies demonstrating the use of distributed acoustic sensing deployed on regional unlit fiber-optic telecommunication infrastructure (dark fiber) for broadband seismic monitoring of both near-surface soil properties and earthquake seismology is presented.

TL;DR: In this paper, a comparison of laboratory-modeling results with a diffusive-viscous-theory model showed that low (<5) values of the quality factor Q can explain the observations of frequency dependence.
