Tsunamis can happen anywhere on the planet where there is a large enough and deep enough body of water.

Tsunami waves can travel thousands of miles across the oceans at speeds close to that of a jet plane. Out in the ocean they're hard to spot, you could be out on a boat and a tsunami wave could pass by and you wouldn't notice it. As the wave comes towards land and the sea gets shallower the wave slows down, the mass of water is compressed into a shorter distance from front to back and the wave builds in height.

The Boxing Day tsunami that caused so much devastation in South East Asia was caused when part of the ocean floor violently lifted upwards, basically an underwater earthquake. Because it was close to land the people had very little warning and the wave came to shore only a few minutes after the earthquake struck. Across the other side of the Indian Ocean people had time to react and move inland and to higher ground, as a result the death toll here was much less than it could have otherwise been.

Earthquakes are just one cause of tsunamis. Following the eruption of the Mount Saint Helen's volcano there was a massive tsunami wave that travelled across Spirit Lake. This was caused by an avalanche of debris from the volcano plunging into the lake and causing a wave 800 feet high (many times higher than the Boxing Day tsunami).

Fortunately the area affected was sparsely populated but when the wave hit the opposite side of the lake it stripped trees and vegetation for half a mile up the hillside.

A similar style event could happen at any time. One of the islands in the Canary Islands (off the coast of Africa) is unstable and a massive rock slide could crash down into the Atlantic Ocean, this could cause a tsunami bigger than anything ever before known and would strike the full length of the eastern coast of the US, up into to Canada, down to South America, and into parts of Europe.

The island has been like this for thousands and thousands of years, there's nothing to indicate the rocks are about to fall at any time now, if the worst did come to the worst the citizens of the US would have many hours notice and would have time to make their way to higher ground.

In the event of a meteorite hitting an ocean a tsunami could be triggered. It would take a sizeable metoerite and such events are few and far between.

These are some possibilities, they're unlikely but could happen. I couldn't give a figure but it would be thousands to one against such a thing happening.

It's very very rare and the chances are very unlikely but it could happen. There's the Mid-Atlantic Ridge out in the middle over the Atlantic Ocean but it's a diverging plate meaning that both sides of it are moving away from each other. But most tsunamis are caused by converging plates which means that the plates are moving towards each other and it causes the water to uplift more. That's why tsunamis commonly occur or tsunami warnings are commonly issued in places that are in the Pacific Ocean.

reality is right, perfect does not equivalent appropriate. attractiveness is interior the attention of the beholder and we each discover some thing perfect and unique related to the Earth. What i come across maximum perfect is discovering to cherish the failings we've on the 2d...discovering to love what you have. by way of fact in any 2d, it incredibly is long previous like that. occasion: organic failures, dropping a kinfolk member, etc. ailment occurs by way of fact if everyone grew to become into healthful, the Earth might over populate. Animals pray and kill to feed their youthful and themselves. We consume animals too. guy's sin? I doubt it. it incredibly is in simple terms the circle of existence. It is going for human beings, places and animals.
