Tsunami in India

 Tsunami in India

On 26th December, 2004 an earthquake and a tsunami occurred in Indian Ocean which had a devastating effect on India. More than 11,000 people died due to Tsunami in India and more than 5,000 people went missing. Southeastern coast and the Andaman and Nicobar Islands are the worst hit areas by tsunami.

Tsunami in India in 2004 caused severe devastation particularly in Nicobar Islands. The saltwater intrusion after the tsunami destroyed farmlands and fresh water sources. Tsunami in India caused damage to communication lines, and many roads and railways were washed out.

Tsunami is travelling ocean waves in a series which are extremely long length. Tsunami occurs primarily by the disturbances of earthquakes in the ocean. Tsunamis can cause damage to the life and property that exists near the ocean. The 2004 Tsunami in India caused severe damage to the sea coasts. All earthquakes do not cause tsunamis. An earthquake that occurs underneath or near the ocean mostly causes tsunamis. In Pacific Ocean there is frequent occurrence of destructive tsunamis as there will be large earthquakes.

The most effected people in general due to tsunami are fishermen as in 2004 tsunami in India. Fishermen lost their shipping vessels, boat, fishing equipment etc. If at all a tsunami in India occurs in future, fishermen would suffer the most, because these are poor and belong to low castes in Indian society. They lose their primary source of income.

The Indian government spent nearly Rs. 29 million to develop a tsunami warning system in India. It has made agreement with the United States to work along with them to alert the scientists about the possible tsunamis in Indian Ocean. Indian Ocean system will not be dependent on the Pacific warning system.

There is little that anything can do to prevent natural calamities like the tsunami in India. But loss of life and property can be reduced with proper planning. For this everyone should have an awareness of the physical nature and phenomenon of the calamity. Tsunamis hazard are to be planned by identifying the most vulnerable areas.

Recently India has tested the UN backed tsunami warning system. Earlier than 2004, there were no warning systems in Indian Ocean that send alerts for possible tsunami. But now a large network of seismographic centers, coast and deep ocean stations, national warning centers are working in Indian Ocean to detect tsunamis and pass warnings. When there is an earthquake in Indian Ocean, data is sent to the Pacific Tsunami Warning Center which is based at Hawaii. These receive earthquake information, new bulletins, telegrams etc. These two centers work to determine the severity of the earthquake and check whether these can produce tsunamis. Earthquakes that occur on land will not cause tsunamis and all the earthquakes that occur in the sea do not cause tsunamis. Tsunamis occur depending on the location and nature of the earthquake. The information about tsunami is sent to the national agencies in the Indian Ocean and they in turn alert their population.

Warning centers of Tsunami in India send warning to the people through radio, television, SMS or email. In small villages the warnings are given over loud-speakers, megaphones etc. In India many NGO groups and communities are involved to teach and coordinate about what should be done in situations of tsunami warnings. Signs of earthquakes or tsunamis should be observed carefully. Earth shakes, sea recedes etc are the warnings of tsunamis.
