Researchers are now studying earthquakes and geology with unused optic fiber cables
So-called dark fiber could help seismologists map the underground and measure our planet s rumbles.
Studies are increasingly starting to show that the same optical fibers that deliver our high-speed internet and video can be used to study earthquakes and geology
As a geophysics undergrad, it was thrilling to learn how earthquakes can be used to study the subsurface. Earthquakes are pretty much the only reason we know anything about the Earth’s internal structure, and they can tell us a lot about the make-up of the crust, mantle, and even the core of our planet. It gets even better: you can “fake” an earthquake with special tools (which can range from a big hammer to dynamite) to assess the geologic structure of the area beneath you. If you have the proper tools to
