Poll published in Science Magazine showed that underwater internet cables be able to detect earthquakes. The discovery could revolutionize natural phenomenon detection by expanding the monitoring network and reducing the cost of sensors. The study was conducted by the UK National Physical Laboratory (NPL) in partnership with Google, the University of Edinburgh, the British Geological Survey and the Italian National Institute of Meteorological Research.

Installation of stationary sensors for control earthquakes in the ocean has a high value and little exists in the world. The vast majority of sensors earthquakes are on the ground. However, there are hundreds of fiber optic cables used to connect to Internet installed at the bottom of the ocean. More than 400 submarine cables have been laid in the world with a length of about 1.3 million kilometers.

NPL researcher Giuseppe Marra explained that small fluctuations in temperature, pressure and vibrations can very little change the speed at which light travels inside cables. Thus, by using instruments capable of detecting these variations, it is possible to detect natural phenomena. The research team was able to detect earthquakes and other “ocean signals” (such as waves and currents) using instruments installed on a 5,680 km submarine cable that connects Southport, England, to Halifax, Canada.
“If we apply this technique to a large number of cables, we can turn this underwater infrastructure into a large number of detectors for earthquakesocean currents and more,” Marra said.
Brian Bapti, another researcher of the study, commented on these other phenomena. “[…] there is the possibility of measuring other phenomena, such as underwater volcanoes and tsunamis,” Bapti concluded.
