Tsunami

One of the most dreaded natural phenomenon's that has caused lot of damage in the recent times is Tsunami (Chopra, 2001). Tsunami happens when their huge volume of water has been displaced from a water body, due to which there are series of waves in a large ocean. Earthquakes and volcanic eruptions that erupt underwater are one of the prime reasons Tsunami happens. There are some other reasons as well that might cause these series of water waves like impact of a meteorite and some other disturbances. Waves of Tsunami are different from some other normal sea waves as they overall length of the waves is on the higher side.

Impact of Tsunami

The overall impact of the Tsunami is mostly felt in the coastal areas, but there are chances that they might affect the whole coastal region due to the aftereffect of the strong waves. They can sometimes eradicate the entire basis of the ocean. The 2004 Tsunami which is also referred as Indian Ocean Tsunami was one of the most devastating as almost 250,000 people were killed due to it. Obviously coastal areas such as Sri Lanka, Indonesia and Japan are some of the most areas that are affected by Tsunami.

Warnings of Tsunami

The warning systems are there as far as prediction of the Tsunamis is concerned and they have achieved moderate level of success. There are people who observe the drawbacks but they are primary warning and sometimes people who are observing the drawbacks have to react quickly to save their lives. Unfortunately, it is really difficult to know the timing and the magnitude of the Tsunami as even the magnitude of the Earthquake is not really easy to determine. But there are some automated systems that are there to make sure that there can still be some sign of Tsunami. One of the most commonly used resource is that of Bottom Pressure Sensors, as they can monitor the pressure of the water.

Regions most Affected by Tsunami

Looking at some of the regions that are most affected by the Tsunami, it can be seen that technologically advanced country such as Japan might do well to make sure that they stay one ahead and it can be seen that they have used Bottom Pressure Sensors to good affect. But regions like Sri Lanka and Indonesia are lagging behind in the technology due to which these calamities have affected these areas the most. So there is this need of international funding in these area's so they can equate themselves the technology.

Economic Cost of Tsunami

The economic costs of these technologies might be quite hard for these economies specially for Sri Lanka, as they have been most affected by these natural ...
