It sounds like you can turn any arbitrary underground fiber into a microphone with a certain sensitivity.

- foobarbecue 3y agoYes, you can. This was first used by the Navy to record / detect submarines, many decades ago. You can also use the cable for distributed temperature sensing (some of my research used this).

- ccakes 3y agoFibreSense have commercialised hardware and software that does just this in an insane amount of detail, it’s very cool https://fibersense.com/ https://fibersense.com/ Not affiliated, just a fan
- mcmcmc 3y agoSounds interesting but the bloated website and nonconsensual cookies make it hard to want to learn more

- _kb 3y agoThere’s a network under Melbourne [0] that’s in use for research what’s possible for city scale sensing. Seems to be an option for seismology, traffic, rainfall, drainage etc. [0]: https://www.rmit.edu.au/research/centres-collaborations/multi-partner-collaborations/combs/projects/mapping-earthquakes-using-optical-fibres https://www.rmit.edu.au/research/centres-collaborations/mult....
- RowanH 3y agoI was listening to a YouTube ( I think it was 60 minutes of all things ) where volcanologists are burying them deep down in icelandic volcanoes to help detect when volcanoes might blow. Sensing the underground magma movement..
