Seismic sound waves crossing the deep ocean could be a new thermometer
- Pick-A-Hill2019 6y agoI'm sure they thought of this already but the mention that underwater microphones (hydrophones) could be even more sensitive, taking advantage of smaller earthquakes brought to mind a previous HN post about using undersea fibre-optic cables to measure earthquakes. I can't find the link to the post but https://www.digitaltrends.com/cool-tech/undersea-cables-detect-earthquakes/ https://www.digitaltrends.com/cool-tech/undersea-cables-dete... or https://arstechnica.com/science/2018/06/seafloor-fiber-optic-cables-can-work-like-seismometers/?comments=1 https://arstechnica.com/science/2018/06/seafloor-fiber-optic... both explain the concept.
