Scientists Saw an Earthquake in Incredible DetailUsing Telecom Cables

The same optic fibers that pulse with the world's Internet traffic are now listening to the pulse of the planet, picking up earthquake tremors in better detail than traditional seismic networks do. In a recent Science study, researchers used 15 kilometers of telecom fiber near Mendocino, Calif., to record the region's biggest earthquake in five yearscapturing in fine detail how the magnitude 7 rupture started, slowed and sped up, accelerating even faster than the speed of sound.

Calif. could detect massive earthquakes with internet cables. Here's how.

Scientists cannot accurately predict large temblors, and those that start offshore are even more difficult to track. But a study published Thursday in Science demonstrates how the same tech that brings you a high-speed internet connection could be used to better understand the massive quakes that rupture in the ocean, and also to improve alerts. The researchers used information from fiber-optic cables on land to quickly detect and map an enormous earthquake off the Humboldt coast last December.
