Learning lessons from the tsunami of December 2004, India Monday unveiled an early tsunami warning system, the first of its kind in the world, which will sound an alert 13 minutes after an undersea earthquake in two potential source regions.
Set up at the Indian National Centre for Ocean Information Services (INCOIS) at Jeedimetla on the city outskirts, the centre is equipped to warn in real-time if sub-duction zone related earthquakes in Andaman-Nicobar-Sumatra island arc and the Makran sub-duction zone north of the Arabian Sea can trigger tsunamis.
Science and Technology and Earth Sciences Minister Kapil Sibal Monday inaugurated the centre, built indigenously in two years at a cost of Rs.1.25 billion with the involvement of 14 different organisations and 150 scientists.
An early tsunami warning can help the 400 million people living in India's coastal to save themselves. The information can also be shared with neighbouring countries.
Sibal said efforts were being made to reduce the warning time to six minutes and thus extend the time-line for alert and evacuation in the areas likely to be hit by tsunami. The earth sciences ministry has established the centre in collaboration with the department of science and technology, the department of space and the Council Of Scientific and Industrial Research (CSIR).
P.S. Goel, secretary, ministry of earth sciences, said the centre comprised a real-time network of seismic stations, bottom pressure recorders (BPR) and tide gauges to detect tsunami-genic earthquakes and to monitor tsunamis.
