DAS sensors also contain more "self-noise" -- background seismic signals that could interfere with an earthquake identification -- than traditional seismic sensors, "but frankly we don't exactly ...

As you might imagine, installing seismic sensors on the ocean floor isn't an easy task. Recently, however, scientists were able to detect seabed seismic activity using something that was already ...

In contrast, Bondi pointed out, “Every meter of optical fiber in our network acts like a sensor and costs less than a dollar to install. You will never be able to create a network using ...

In California, seismometers are often separated by 20 or more miles even in the most hazardous areas. Fiber-optic sensors may help fill those data gaps.

Their work showed how unused fiber-optic cable could serve as a highly sensitive earthquake sensor. This is one of the first case studies to employ a large regional network as a seismic sensor.

Using "Curie" - Google's 10,000-kilometer-long underwater fiber-optic cable connecting Los Angeles, California and Valparaiso, Chile - researchers have demonstrated a novel method for detecting ...

They’re conducting experiments now with lit fibers, while also planning fiber-optic monitoring of seismic events in a geothermal area south of Southern California’s Salton Sea, in the Brawley seismic ...

Instead of taking seismic measurements at a single point, like a seismometer does, DAS is more like a miles-long string that forms one giant earthquake sensor.

Lipovsky says the fiber optic cables have allowed the team to observe waves that echo off of converging seismic plates with higher precision. He says they can detect these waves at a distance of ...

A 100-kilometer fiber optic cable used in the system can effectively replace a linear array of thousands of conventional seismic sensors.
