Hyderabad: The Indian Tsunami Early Warning System (ITEWS) wing of the city-based Indian National Centre for Ocean Information Services (INCOIS) is developing the 3D GIS map (Geographical Information System) for Machilipatnam to take the early warning system to the next level of sophistication.

The mapping will enable the government to identify the potential victims of a tsunami by name, address and contact number. This will help the disaster relief forces and volunteers to warn the likely victims without loss of precious time after a tsunami hits the coast at a given location.

INCOIS had developed similar project for Cuddalore and Nagapattinam in Tamil Nadu. Similar map is currently under preparation for Puducherry as well. India’s tsunami early warning system is constantly evolving new strategies like the 3D GIS. The GPS back-up is provided by another city-based organisation, the National Geophysical Research Institute (NGRI).

The state-of-the-art ITEWS operates round-the-clock at the city-based Indian National Centre for Ocean Information Services (INCOIS), which works under the Union Ministry of Earth Sciences.

Stating this at a workshop held on the occasion of 10th anniversary of the tsunami which occurred on December 26, 2004, the Union Minister for Science & Technology and Earth Sciences, Harsh Vardhan, released the 'SOP (Standard Operating Procedure) Training Manual drafted by the ITWES.

In his address to the workshop, the Minister pointed out that India has never issued a false alarm so far in the past seven years since ITWES came became fully operational. Countries like Japan issue alarms to their citizens and many times, they turn out to be false, he said.

The SOP manual divided the tsunami alerts into four categories based on their intensity: namely, 'Warning' (highest intensity), 'Alert', 'Watch' and 'Threat Passed' (lowest intensity).

Dr Harsh Vardhan also inaugurated the Staff Residential Complex on the INCOIS premises. The Minister along with MoS Sujana Chowdary later inspected other activities of the INCOIS wings during their visit.
