Submarine data cables could help detect earthquakes and tsunamis in the future. An indication of this was seen in 2020.

At the time, one of Google's fiber optic models detected strange activity by checking for distortions in light pulses along the cable.


The researchers' intention is to use the resource to make the ocean seismic monitoring process cheaper.

For Zhongwen Zhan, assistant professor of geophysics at the California Institute of Technology, it would be great to be able to take advantage of the telecommunications cables that are already in operation as sensors.

In the future, in addition to detecting these anomalies, the cables may also issue early warnings to people on the coast about the approach of earthquakes.

Another advantage is that they will be able to support studies on the functioning of earthquakes on the seabed.

Google was also excited to be able to collaborate with the efforts. In a statement, the company stated that it is excited about the possibility of using its submarine cable infrastructure for social benefit.
