A tsunami wave is also formed due to disturbances that can displace the water column creating a rise or fall in the level of the ocean above.
Tsunami is commonly referred to as a sea monster. Tsunami waves cut across the sea with a tremendous speed. Once it reaches the land, it sucks most of the water out of the harbor, back to the sea.
Then it comes back with an amazing speed and the waves may rise more than 100 feet tall and flatten whole villages.
Often before a tsunami hits, there is a giant vacuum effect, and water is sucked from harbors and beaches of the coastal areas.
People are able to see the bare sea bottom littered with collapsed fish and stranded boats.
This is usually the first symptom of tsunami Tsunamis are referred to as tidal waves because they come towards land. However, tidal waves of the tsunami are very violent.
Tsunami may be a series of waves called a series generated in Associate in Nursing passing body of water by a full of life or abrupt disturbance that vertically displaced a water column.
It can be generated by any disturbance that displaces a large mass of water such as an earthquake, landslide, volcanic eruptions, explosions, or meteor impact.
They can submerge the whole coastlines, villages, etc, causing devastating damage to property and life. They can be generated when the sea floor abruptly deforms and vertically displaces the overlying water.

Tsunamis are common throughout Japanese history. Till now, 195 events in Japan have been recorded. In the Nineteen Fifties, it completely was discovered that larger wave will be caused by landslides, explosive volcanic action, and impact events when they contact water.
The tsunami caused by these mechanisms, generally affect the small area in the sea and disperse quickly. This kind of tsunami hardly affects the coastlines that are at a distance from the source; however, an extremely large landslide could generate a “mega-tsunami” that might have ocean-wide impacts.
While it is not possible to prevent a tsunami, in some particularly tsunami-prone countries some measures have been taken to reduce the damage caused on shore. Japan has enforced an intensive programme of building wave walls of up to four.5 high before of inhabited coastal areas
In deep water, a tsunami can travel at 700 km per hour. But in shallow water, near the coast, it gets slower and water mass rises up to 50 meters. A tsunami is very much destructive. It can destroy coasts of land, uproot trees, and wipe out towns.
Our country got affected by tsunami three times in the history. Last time it was in December 2004. It was caused by an underwater earthquake of magnitude 9.3 Richter scale. The epicenter of the quake is said to be Sumatra island of Indonesia. It has been the deadliest tsunami in recorded history.
In Indonesia, Sri Lanka, Thailand and Hong Kong, thousands of people lost their lives and up to five million people have been displaced by the tsunami that affected large areas of Asia.
Three million out of those affected are in Indonesia alone and another one million in Sri Lanka. The rest were spread between India, Maldives and other nations hit by tsunami waves.
The man has achieved a lot through science and technology. But there is still something beyond his control. This is nature. Tsunami is yet another reminder that man has not been able to conquer nature.
