Article describing the how’s and why’s of Tsunamis. Very informative for the curious among us.
Most of us in the United States call them “tidal waves,” but they have nothing to do with the tides. Experts call them Tsunamis (pronounced “sue-nah-mes”), a Japanese word meaning “harbor wave”. Pacific coast residents, many of whom live just a few miles from the ocean, are in danger if a tsunami occurs. But few people know how tsunamis are generated or even just what they are.
