How tsunamis work

You're standing on a beach, and suddenly the ocean pulls back fast, leaving fish flopping on wet sand and boats stranded on the harbor floor. It looks like the sea is taking a deep breath—and for anyone who knows what that means, it's the only warning they'll get before a tsunami strikes. In this video, we explore the incredible science behind tsunamis to find out what makes them so different from the normal wind-driven waves we see every day. We'll dive down to the seafloor to see how shifting tectonic plates displace the entire water column, creating a wave so strange that it warns you by disappearing, and so stealthy it can cross an entire ocean unnoticed.
