Seafloor Cables Get Smarter
Tsunamis (海啸) are giant waves caused by Earthquakes, and they're often devastating (毁灭性 的), especially when they hit an area where a lot of people live. Because underwater earthquakes are hard to detect, tsunamis can happen with little or no warning. Now "smart" cables could help change that.
Hundreds of cables already crisscross (纵横交错) the ocean floor, carrying our internet and cellphone data. Scientists say when new cables are put on the seafloor, sensors could be added to them. The sensors would monitor seafloor motion, water temperature and pressure (压力), so that warnings could be sent as soon as an earthquake big enough to cause a tsunami to happen. Scientists could also study climate change by looking at changes in seafloor temperature.
Portugal and the South Pacific islands of New Caledonia and Vanuatu have signed deals to have the new "smart" cables installed. Scientists hope more countries will follow soon.
