Voting is Your POWERResearchers are repurposing the planet’s vast network of fiber-optic cables to detect underground vibrations and map Earth’s interior in real time.
Pulses of laser light can register tiny disturbances in the glass fibres allowing scientists to monitor earthquakes, volcanic systems, and even the boundary between crust and mantle.
Projects in Istanbul and Athens have already produced street-level seismic risk maps, while U.S. teams are imaging deep fault lines and geothermal reservoirs.
With 4 billion kilometres of cable laid across cities and oceans, this method could radically expand subsurface monitoring—transforming our understanding of Earth’s hidden architecture #earth #news
