Tsunami: The Water Destruction

History Of Tsunami
In 479 BC, when Persian soldiers precedes to Greek city of Potidoaea. The tide retreated much farther than usual, leaving a convenient invasion ward but this wasn't distract of luck. Before they'd crossed the halfway, the water returned in a wave higher than anyone had ever seen, drowning the attackers. The Potidaeance believed they have been saved by the Wrath of Posiden. But what really saved them was likely the same phenomena on that had destroyed countless others; A Tsunami.

What is Tsunami?
Tsunami is a Japanese word, means; Harbor Waves. Although Tsunami are commonly known as the tidal waves. But they are in related to tidal activity caused by the gravitational forces of the Sun and Moon. In many way the Tsunami is dislarger version of regular waves. They have Trough & Crest and consist not of a moving water but the movement of energy through water.

The Formation
The difference is in where the energy comes from? For a natural Ocean waves, it comes from wind because this effects only surface. This waves are limited in size and speed but Tsunami is caused by energy originated by underwater form Volcanic Irruption, a Submarine Landslide or most commonly An Earthquake on Ocean floor. It is caused when Tectonic plates from the Earth surface slip, releasing a massive amount of energy into the water. This energy travels up the surface, displeasing water and raising it above the normal sea level. But the gravity pulls it down which makes the energy repel outwards horizontally. Thus the Tsunami is born moving it over 500 miles/hr.

When its apart from shore, a Tsunami can be barely detectable, since it moves through entire depth of the water. But when it reaches in shallow water, something called Wave Shoaling occurs. Because there is less water to move through , there is massive amount of energy is compressed. The wave speed slows down while its height rises as much as 100ft (30.48 meters).

It's Destruction
The word Tsunami, the Japanese means harbor waves comes from the fact that it only seems to be appear near the coast. If the Trough of the Tsunami reaches towards first, the water will see farther than the normal before the wave hits, which can be misleadingly dangerous. A Tsunami not only drown people near the coast but level buildings and trees from mile elements and more specially in low living areas. As if that wasn't enough the water then retreax dragging with the newly created Debra and anything or anyone unfortunate enough to be caught it path.

Recent Tsunami
In 2004, the Indian Ocean's Tsunami was one of the deadliest natural disaster in history. Killing over 200 thousands of people throughout South Asia.
So how can we protect ourselves against the destructive forces of nature. People in some areas having attempt to stop Tsunami with Sea walls, flood gates and channels to divert the water but these are not always effective. In 2011, a Tsunami surpassed the fluid walls protecting Japanese Fukushima powerplant causing a nuclear disaster in addition to claiming over 1800 lives.

Many scientists and policy maker are instead focusing in early detection, maintaining underwater pressure and Seismic activity and establishing global communication networks for quickly distributing alerts.

When the nature is too powerful to stop, the safest cause is to get out of it's way.
