Fiber optic lines to help detect slightest jostles in seismic activity

22 October 2017 0

As the technology is progressing, we’re able to better understand seismic activities, better detect earthquakes and have equipped our self to withstand earthquakes. Previously acoustic sensors were used that were installed within the surface of the earth helping in detecting the magnitude of the tremors. Now in the recent happenings, a couple of volunteers have found a highly useful way to utilize fiber optic network that many of us already use for our internet connections.

Their work enables the laser interrogators to look for any disturbances in the fiber optic lines that when jiggles, seismic activity is detected. This won’t only help to detect any tremor waves and determine their seriousness, it could even spot minor quakes that could generally go unnoticed otherwise.


Earlier the same optic fibers were used though on their outer side, sound-detecting sensors were installed or attached directly to the ground to look for any irregular activities. Though currently, the biggest challenge to implement this new finding is the lack of widespread fiber optic networks. Fiber optic isn’t common all around the globe and it would only take time for it to be implemented in majority countries and regions around the world.

Currently, it seems that it's quite expensive to implement the new technology compared to rolling out sensors though looking forward to the sheer precision of utilizing fiber optic this way, we could expect it to become a commonly used strategy to study seismic activity in years to come.
