The Tohoku earthquake caused a tsunami. A tsunami—Japanese for “harbor wave”—is a series of powerful waves caused by the displacement of a large body of water. Most tsunamis, like the one that formed off Tohoku, are triggered by underwater tectonic activity, such as earthquakes and volcanic eruptions.
