Undersea cables carry Internet traffic across continents. They are part of the critical information infrastructure of the modern world.

Scientists started using these cables as a global network of sensors that monitor seismic and other changes at the seabed previously beyond the reach of the scientific community.

As Wired indicated in the recent coverage Where there's cable, there's potential data.

Geoscientist Philippe Jousset said 'You can interrogate any fibre under the sea, covering all of the Earth'.

Undersea cables could be also used as early-earning tools for tsunami as they can detect any tectonic shifts on the seabed.
