Tsunami : “Then he heard a distant rumble - louder than thunder.
Regions with a high risk of Tsunamis may use Tsunami warning systems now available to detect Tsunamis and warn the general populace before the waves reach the coasts. In some communities on the West coast of the United States, which is prone to Pacific Ocean Tsunamis, warning signs advise people where to run in the event of an incoming Tsunami. Computer models can roughly predict Tsunami arrival and impact based on information about the event that triggered it and the shape of the sea floor and the coastal landmass. One of the early warnings comes from nearby animals. Many animals sense danger and flee to higher ground before the water arrives. Monitoring their behaviour closely could provide advance warnings of earthquakes, Tsunamis etc.
In 2011, Earthquake Research Committee of Japanese Government announced that Tsunami forecasts would be started to alert the public in advance about the approaching Tsunamis in near future. This would comprise Tsunamic height, attack area and probability of occurrence within 100 years. Such forecasts should be soon activated in the Indian sub-continent also. The Intergovernmental Oceanographic Commission, UNESCO is working out strategies for this area.
Coastal areas of India are sitting on a ‘Tsunami-bomb’. Awareness and robust measures are the needs of the hour.
