University of Michigan (U-M) researchers have demonstrated the potential for using existing networks of buried optical fibers as an inexpensive observatory for monitoring and studying earthquakes. The study provides new evidence that the same optical fibers that deliver high-speed internet and HD video to homes could one day double as seismic sensors.
“Fiber optic cables are the backbone of modern telecommunications, and we have demonstrated that we can turn existing networks into extensive seismic arrays to assess ground motions during earthquakes,” said U-M seismologist Zack Spica, first author of a paper published in the journal JGR Solid Earth.
The study was conducted using a prototype array at Stanford University,…READ MORE
