The country has approved setting up a tsunami warning system in the Indian Ocean at a cost of Rs 125 crore, a former official of the Ocean Development Department said in Hyderabad Friday.
India has decided to set up the Indian Ocean Global Ocean Observation System connecting all seismic stations to share tsunami related information, former secretary of the department Dr Harsh K Gupta said.
Pointing out that it was essential to record occurence of a tsunami, Gupta told an international seminar on 'Natural Hazards - Disaster Mitigation' that sensors would be planted at the bottom of the Indian Ocean by September 2007.
Meanwhile, National Remote Sensing Agency Director Dr R R Navalgund, speaking on the 'Role of Remote Sensing in Disaster Management', said three satellites would be launched in next two-three years.
'Cartosat-2', to be launched early next year, would provide data at one metre spatial resolution. The second, 'Ocean Sat-2', will have two payloads, including ocean colour monitor, useful for fisheries, and scattrometre, which would provide data of wind vector over ocean surfaces, he said.
The third, 'Ri-Sat' or radar imaging satellite, would carry a c-band synthetic aperture radar providing information on inundated areas, he added.
