Answer 1

tsunami is a series of waves when a body of water, such as an ocean is rapidly displaced on a massive scale. Earthquakes, mass movements above or below water, volcanic eruptions and other underwater explosions, and large meteorite impacts all have the potential to generate a tsunami. The effects of a tsunami can range from unnoticeable to devastating.

The term tsunami comes from the Japanese language meaning harbour ("tsu", 津) and wave ("nami", 波). Although in Japanese tsunami is used for both the singular and plural, in English tsunamis is often used as the plural. The term was created by fishermen who returned to port to find the area surrounding their harbour devastated, although they had not been aware of any wave in the open water. A tsunami has a much smaller amplitude (wave heights) offshore, and a very long wavelength (often hundreds of kilometres long), which is why they generally pass unnoticed at sea, forming only a passing "hump" in the ocean.

Tsunamis have been historically referred to as tidal waves because as they approach land, they take on the characteristics of a violent onrushing tide rather than the sort of cresting waves that are formed by wind action upon the ocean (with which people are more familiar). However, since they are not actually related to tides the term is considered misleading (even though not all tsunami occurred in harbours) and its usage discouraged by oceanographers.

Answer 2

tsunami means big. the earthquake occurring in the oceans is the main cause for it's occurrence.the tsunami, which occur ed in 2006, is also due to the same reason. it is mainly bcoz of the earthquake in the islands which spread in to the waters. the earthquake usually causes earth tremors. when it occurs in waters it causes the water to rise up n results in very high tides which we saw in the form of tsunami.
almost all the coastal areas are badly affected. i don't have the statistics. but as far as i knew, tamilnadu is the most worstly affected. a memoir was also built there for those who died in the tsunami.

Answer 5

tsunami means harbor wave,or something close to that..
causes?
undersea quakes...undersea land slides...the displaced "slide" creates a wave from the bottom of the ocean...it has a huge wave length..[wave propagation from physics would help explain] and that energy/wave length only intensifies when the wave approaches shallower water....as in a harbor, seashore, beach .....
