34. WHAT DOES TSUNAMI MEAN Tsunami is a Japanese word with the English translation, "harbor wave ." Represented by two characters, the top character, "tsu," means harbor, while the bottom character, "nami," means "wave." In the past, tsunamis were sometimes referred to as "tidal waves" by the general public, and as "seismic sea waves" by the scientific community . The term "tidal wave" is a misnomer; although a tsunami's impact upon a coastline is dependent upon the tidal level at the time a tsunami strikes, tsunamis are unrelated to the tides. Tides result from the imbalanced, extraterrestrial, gravitational influences of the moon, sun, and planets. The term "seismic sea wave" is also misleading. "Seismic" implies an earthquake-related generation mechanism, but a tsunami can also be caused by a nonseismic event, such as a landslide or meteorite impact.
35. A tsunami (pronounced tsoo-nah-mee ) is a wave train, or series of waves, generated in a body of water by an impulsive disturbance that vertically displaces the water column. Earthquakes, landslides, volcanic eruptions, explosions, and even the impact of cosmic bodies, such as meteorites, can generate tsunamis. Tsunamis can savagely attack coastlines, causing devastating property damage and loss of life. What is a tsunami?

39. Sumatra Feature: Pictures and video from the 2004 tsunami highlighted the vast difference between tsunamis and wind generated waves . Because tsunamis have very long wavelengths they come ashore more like a long lasting flood wave rather than the breaking surf usually seen at the beach. This diagram illustrates the difference between tsunamis and wind waves when they come ashore. Next
