Can undersea cables detect earthquakes?

Undersea cables are not only crucial for internet traffic but also serve as a global network of sensors to monitor seismic activity and changes at the seabed. They have the potential to detect tectonic shifts early, aiding in earthquake and tsunami warnings.

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.

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