Question

What is Tsunami and what was the cause and consequences?

Answer 1

A Tsunami is a wave caused by an undersea earthquake. It is sometimes called a tidal wave, because when it comes ashore it resembles a tidal bore, which is a wave that can travel up a river mouth as the tide comes in. Some Tsunamis are very large and cause massive flooding and death and destruction on coastal areas.

Answer 2

Tsunamis are huge waves of water caused by earthquakes under the ocean. the energy from the earthquake displaces the water and creates a huge fast moving wave. When the wave comes ashore it destroys everything in its path. You should look up the wikipedia.org entry on tsunamis for more information.

Answer 3

an underwater movement of the sea floor ,like a tremor or earth quacke that sets a wave in to motion

A super Tsunami is set of by a mass of land sliding into the water ,like is expected from the philipines, that will set a wave into motion 25 meters high that can cross the ocean and for example hit the east coast of America wiping the coastline clean of everything (25 meters high)

Answer 4

Tsunami is "a series of traveling ocean waves of extremely long length"

Tsunamis are "generated by disturbances associated primarily with earthquakes occurring below or near the ocean floor. Underwater volcanic eruptions and landslides can also generate tsunamis. In the deep ocean, their length from wave crest to wave crest may be a hundred miles or more but with a wave height of only a few feet or less. They cannot be felt aboard ships nor can they be seen from the air in the open ocean. In deep water, the waves may reach speeds exceeding 500 miles per hour.

Tsunamis are a threat to life and property to anyone living near the ocean."
