Question

Define tsunami with causes and effects?

Answer 1

Tsunami means harbour wave in Japanese. The shock waves from an earthquake often create giant waves. They tower up when they reach land, destroying whole village and towns.

Answer 2

You can follow the link here, you can always use wikipedia or google scholar for your work

Answer 3

TSUNAMI

- Japanese term meaning wave (“nami”) in a harbour (“tsu”). A series of traveling waves of extremely long length and period, usually generated by disturbances associated with earthquakes occurring below or near the ocean floor.

CAUSES

"A tsunami can be generated when converging or destructive plate boundaries abruptly move and vertically displace the overlying water. It is very unlikely that they can form at divergent (constructive) or conservative plate boundaries. This is because constructive or conservative boundaries do not generally disturb the vertical displacement of the water column. Subduction zone related earthquakes generate the majority of all tsunamis. ..."

EFFECTS

"As far back as 1480 B.C. history records destruction by tsunami-huge ocean waves-with loss of life and property. Today population pressures on coastal areas bring more and more communities and installations under this threat. Tsunami warning systems employing advanced technological instrumentation require public education and confidence in government agencies for effectiveness. ..."

Answer 4

A big sea wave not to be used for surfing.

Answer 5

tsunami means harbour waves in japanese.A tsunami  is a series of waves created when a body of water, such as an ocean, is rapidly displaced. Earthquakes, mass movements above or below water, some volcanic eruptions and other underwater explosions, landslides, underwater earthquakes, large asteroid impacts and testing with nuclear weapons at sea all have the potential to generate a tsunami. The effects of a tsunami can be devastating due to the immense volumes of water and energy involved. Since meteorites are small, they will not generate a tsunami.

The Greek historian Thucydides was the first to relate tsunamis to submarine quakes, but understanding of the nature of tsunamis remained slim until the 20th century and is the subject of ongoing research.

Many early geological, geographic, oceanographic etc; texts refer to "Seismic sea waves" - these are now referred to as "tsunami."

Some meteorological storm conditions - deep depressions causing cyclones, hurricanes; can generate a storm surge which can be several metres above normal tide levels. This is due to the low atmospheric pressure within the centre of the depression. As these storm surges come ashore the surge can resemble a tsunami, inundating vast areas of land. These are not tsunami. Such a storm surge inundated Burma or, Myanmar in May 2008.
