Tsunami mean:
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.

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
What is Tsunami?
Tsunami are large, powerful waves caused by sudden displacement of large quantities of water in the sea / ocean. Common causes for the displacement of large quantities of water are: earth quakes, volcanic activity and landslides.
They can also be caused by detonation of nuclear devices under water, or by the impact of an asteroid As the wave of a tsunami moves into shallower water, it gets much higher, so they can be very big and very destructive when they hit coastal areas.
Sometimes (but not always) the water will recede dramatically just before a tsunami strikes a coastal region - if you see the sea suddenly pull back, going further out than a normal low tide in a very short time then you really want to get out of there as quickly as possible and seek safety!
