Tsunami is a series of strong ocean waves that sends surges of water, sometimes reaching height of many meters. This natural disaster occurs due to the volcanic eruptions in the oceans beds. Earthquakes and landslides are also responsible for tsunamis. Tsunami can create devastating impact near the coastline areas. Tsunamis caused by the earthquakes or volcanic eruptions underneath the seas are likely to be predicted.
Greek historian Thucydides investigated in his book History of the Peloponnesian War’ about the causes of tsunami. He was the first to claim that ocean earthquakes must be the cause of tsunami.
The disaster caused by waves generated because of earthquake and whose main point is beneath the water is called ‘tsunami’. The term ‘tsunami’, is also referred as tidal waves. Tsunami is a series of ocean waves with very long wavelength. It produces strong waves of water that moves landwards. The inland movement of water is much greater and lasts for a longer period, giving an impact of an extreme high tide.
On 9th July 1958, the biggest tsunami wave thus far recorded in history took place in a bay located in Lituya Bay along Alaska coast. After quake, a massive mass of rock fell into the bay waters from a nearby cliff. Its impact produced a wave that reached height of 524 meters. It is regarded as the biggest tsunami wave in history.
These destructive waves can also be produced in waters of lakes or bays. As the waves, approach the coast, its largeness increases. However, its size is quite low in deep-sea areas. Tsunami waves generating in bays or lakes do not travel long distances. They may not prove as destructive as the waves generated in the oceanic waters. Tsunami can travel in all directions from its main point. In December 2004, a series of tsunami waves were experienced in India. However, its origin was located in Indonesia. As many as two lakh people lost their lives as the waves travelled thousands of kilometers in countries like Indonesia, Thailand, Malaysia, India, Bangladesh, Sri Lanka and Maldives.
Tsunamis mainly occur in the Pacific Ocean. There are more possibilities that they take place where there are large water bodies. Open bays and coastlines next to very deep water may shape the tsunami further into a step-like wave. Countries where tsunamis are commonly expected take preventive measures to reduce the damages caused onshore. To protect populated coastal areas many tsunami walls of up to fifteen feet are constructed in Japan. Special channels are built to redirect tsunami water safely. However, their efficiency has been challenged because often waters over top the barriers.

The three different views within India about the type of relationship India should have with the United States of America are :
- Indian analysts who see international politics largely in terms of military power are fearful of growing closeness between India and the US. They prefer that India should maintain its distance from the US and should focus upon increasing its own comprehensive national power.
- Other analysts see the growing convergence of interests between the US and India as a historic opportunity for India. They suggest a strategy that would allow India to make advantage of US hegemony and the mutual convergences to establish the best possible option for itself.
- Some other groups of analysts would advocates that India should take a lead in establishing a coalition of countries from the developing world. Over the time, this coalition would become more powerful and may succeed in weaning the hegemon away from its dominating ways. Hence, the India-US relations are too complex to be manged by a single strategy.
