Detecting Tsunamis
Undersea Internet cables aren’t just for transferring data between continents, at least if researchers from the National Oceanic and Atmospheric Administration are right. Reports Engadget:
While they haven’t moved beyond computer models just yet, the group has apparently found that voltmeters attached to the end of an undersea cable are able to detect the small electric field stirred up by tsunamis, which measure around 500 millivolts.
Now that’s cool.
