Fibre-optic cables laid under the sun for communication systems that form a global telecommunications network can help monitor landfall as well as assess hidden geologic structures. A new study claimed this. The study, published in the journal Science, reported that during an experiment, researchers found fiber-optic cables spread over a stretch of 20 kilometers under the sea, equivalent to 10,000 earthquake monitoring stations.

According to media reports, researchers from the University of California at Berkeley, US, used these cables to assess the devastation caused by the 3.5 magnitude earthquake and the underwater earthquake during their four-day experiment. To detect this, he used a technique in which light can be detected through a device and also to detect earthquake waves. Also, it can also know how backscatter electrons work when the cable is stretched due to the earthquake.

Let us tell you that the researchers measured the changes on every two meters of the cable and converted the 20 km section into 10,000 individual seismic sensors. Researchers said, 'Through this technique, such fault systems have also been identified, which were not detected till now. Apart from this, it can also be used to observe tides and storms. Researchers have given this technique called 'Distributed Acoustic Sensing'. It was previously used for testing with a fiber-optic cable on land, but now it can also be used to get data of activities under the sea in areas where limited stations for earthquake monitoring are in number.
