Many of the world’s largest and most devastating earthquakes strike beneath the ocean, where the lack of sensors makes quick warnings difficult. Most monitoring stations are on land. “If we have a big ...

The same fiber optic networks that provide internet can simultaneously act as earthquake sensors, as demonstrated in a new study. In California, thousands of miles of fiber optic cables crisscross the ...

Scientists have demonstrated a new fiber-optic sensing method that detects strain and displacement by reading interference patterns directly in the electrical spectrum of a photodetected signal. The ...

Since the first fiber optic cables rolled out in the 1970s, they've become a major part of everything from medical devices to high-speed internet and cable TV. But as it turns out, one group of marine ...

SAN JUAN ISLAND — As dawn broke over San Juan Island, a team of scientists stood on the deck of a barge and unspooled over a mile of fiber-optic cable into the frigid waters of the Salish Sea. Working ...

The moon may soon get a high-tech seismic sensing system — and it could be as simple as rolling out cables across the lunar surface. Two recent studies suggest that fiber-optic cables laid directly on ...
