what cause tsunami?

Answer 1

A tsunami is a series of waves created 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, landslides, large meteorite impacts and testing with nuclear weapons at sea all have the potential to generate a tsunami.

A tsunami can be generated when the plate boundaries abruptly deform and vertically displace the overlying water. Such large vertical movements of the Earth’s crust can occur at plate boundaries. Subduction earthquakes are particularly effective in generating tsunami.

Answer 2

Tsunami is caused by the landslide which landed in the ocean and cause big wave called Mega Tsunami. it's more powerful & take away watever comes on it's way. Another is caused by earthquick under the ocean.

Answer 3

Usually an earth quake or earth tremors under the sea, on occassion a meteor that hits the earth will 'splash' creating a big wave, sometimes volcanos cause tremors or else displaced debris from the volcano that falls into the sea will create a tsunami

Answer 4

A tsunami can be generated by any disturbance that displaces a large mass of water, such as an earthquake, landslide or meteor impact.

Answer 5

Earthquakes on the ocean floor cause a huge wave to form and it builds up height as it reaches the shore. If there is a fault or if its near a plate boundry its more likely to have an earthquake on the surrounding shores.

Answer 6

Earthquakes, Volcanoes, Large Landslides and even Asteroid Impacts. Any thing that is large enough to produce the force required to set things in motion.

Answer 7

Earthquakes.

Answer 8

An earthquake on the ocean floor.

Answer 9

plate shifting in the ocean that causes a shock wave and a big wave to start.

Answer 10

earthquakes onshore. A Meteor impact is also possoble but very rare.
