what should be done to know about the tsunamis approaching to strike India?

Sir, around a hundred and thirty years ago, on 27.8.1883, the tsunami waves generated as a result of the eruption of Krakatau Volcano situated to the south of Sumatra Island, struck the countries around the Indian Ocean, including India, one hour after striking the southern part of the Andaman Islands.

Similarly, on 26.12.2004, the tsunami waves generated as a result of the occurrence earthquake in the north eastern region of the Sumatra Islands also struck the countries around the Indian Ocean, including India, one hour after striking the southern part of the Andaman Islands.

Nobody can expect that a similar incident which has already happened twice will not repeat itself in future.

This is because under sea earthquakes are a regular feature in the region of the Sumatra Islands where there are a number of volcanoes.

This proves the possibility of the generation of more tsunamis in region of the Sumatra Islands, which may strike India.

So, the question arises as to what should be done to know about the tsunamis approaching to strike India?

The tsunamis which approach the countries around the Indian Ocean, including India will be known one hour before if surveillance cameras can be installed in the Light House situated in the southern coastal area of the Great Nicobar Island which is at the extreme south end of Andaman Islands and the shore is monitored.

On the basis of this, people living in the coastal areas of countries surrounding the Indian Ocean can be saved from the danger of tsunami by alerting them one hour before and instructing them to move to safer places.
