what is tsunami????

A tsunami is a very large wave, often caused by an earthquake, that flows onto the land and destroys things.

SEA WAVE

 any other answer

 Tsunami is a series of water waves caused by the displacement of a large volume of a body of water. Tsunamis are generated when the earthquakes occur beneath the sea, the water above the sea is displaced from its equilibrium position. It cause a series of waves. When large areas of the sea floor rises that results in large waves, a tsunami is created.

A tsunami is a serie of water waves caused by the displacement of a large volume of water mainly by earthquakes, volcanic erruptions and other underwater explosions. Tsunamis can be very disastrous to people living near the coast.

.

it is a natural disaster in which a huge wave sweeps down the land..

It is a natural disaster caused by the earthquake occurs inside the earth's surface and the magnitude over 8 is very dangerous.

Tsunamiare large, powerfulwater waves caused by sudden displacement of large volume of water in the sea / ocean. Although relatively infrequent, violent volcanic eruptions represent also impulsive disturbances, which can displace a great volume of water and generate extremely destructive tsunami waves in the immediate source area. According to this mechanism, waves may be generated by the sudden displacement of water caused by a volcanic explosion, by a volcano 's slope failure, or more likely by a phreatomagmatic explosion and collapse/engulfment of the volcanic magmatic chambers. One of the largest and most destructive tsunamis ever recorded was generated in August 26, 1883 after the explosion and collapse of the volcano of Krakatoa (Krakatau), in Indonesia. This explosion generated waves that reached 135 feet, destroyed coastal towns and villages along the Sunda Strait in both the islands of Java and Sumatra, killing 36, 417 people. It is also believed that the destruction of the Minoan civilization in Greece was caused in 1490 B.C. by the explosion/collapse of the volcano of Santorin in the Aegean Sea.
