There isn't an underground nuke detonated in the world that goes unnoticed with all the equipment laying at the bottom over every ocean, everywhere. You thought they were just laying f-o cable around the world, did you?

For the most part yes. And no, I don't believe that we cover every region of the worlds oceans with bomb detecting sensors.

Every time fiber optic cable is laid on the ocean's floor, or even repaired 'maintained', etc., there are more than 10 different things going on that have nothing to do with people talking over a cable. And, rest assured, the Korean peninsula has been a priority for a long, long, long time.
