Seismologists at Caltech developed a method for the detection of natural disasters — namely earthquakes — that leverages the capabilities of underwater telecommunication cables already in operation. The method, which does not require additional equipment or instrumentation, analyzes light that travels through these so-called lit fibers to monitor earthquakes and ocean waves, converting the fibers into geophysical sensors.
Previous efforts based on optical fiber infrastructure for the study of seismicity have used “dark” fibers, meaning those that are out of active use. Scientists have also relied on other scientific instruments beyond those that classify as optical. Using optical fiber infrastructure already…READ MORE
