a tsunami is a series of gigantic waves. The word "tsunami" is made up of two Japanese words: "tsu" (which means harbor) and "nami" (which means wave). When a tsunami forms far out at sea, it is often barely noticeable. When tsunami waves form near a shore, however, the results can be devastating for people and buildings near the shoreline.
