Originally deployed to record re-entry signals of the OSIRIS-REx return capsule, a T-shaped fiber optic cable draped across ...

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 down ...

Celeste Labedz heard a sound like thunder roll across the ice. She was standing on Alaska’s Taku Glacier, a vast field of snow-smothered ice between towering mountains, when the icequake began: a ...

Each hair-thin glass fiber in a buried fiber optic cable contains tiny internal flaws -- and that's a good thing for scientists looking for new ways to collect seismic data in places from a busy urban ...

Fiber-optic cables that constitute a global undersea telecommunications network could one day help scientists study offshore earthquakes and the geologic structures hidden deep beneath the ocean ...

EU researchers are exploring how undersea communication cables can double-up as environmental and seismic sensors—a potential game-changer for early warning systems. Subscribe to our newsletter for ...

Distributed acoustic sensing uses the tiny internal flaws in a long optical fiber as thousands of seismic sensors. An instrument called an interrogator at one end of the fiber sends laser pulses down ...

Integrating fiber-optic seismic arrays on the Moon offers a robust approach to studying lunar geology, leveraging advanced DAS technology for detailed insights.
