Internet cables that crisscross the sea-floor could be use to detect earthquakes and tsunamis or monitor how climate change alters ocean currents. Cable-based sensors could identify the “epicentral area” of an earthquake in the same way as land-based seismometers, the researchers suggest, Because installing permanent sensors to monitor the ocean floor is very costly, only a few exist globally, the scientists say. What is your take on using sea cables to detect earthquakes?
