Taking a lesson from last year's tsunami disaster, sensors are being planted in the seabed to record seismological changes, according to the Indian Space Research Organisation.

Over 2,50,000 people died in nine countries in the tsunami.

ISRO is taking up the study on tsunamis and changes in the seabed in coordination with the Geological Survey of India and oceanography and meteorological departments, ISRO chairman and Department of Space secretary G Madhavan [Images] Nair said in Vijayawada.

"Sensors would be planted in the seabed to study the data of sea waves and frequent changes in the seabed, which caused the tsunami. The sensors will have connections with satellites which in turn would give an idea of the changes of waves in the ocean," Nair, who was at Tenali in Guntur district on Wednesday to receive the 13th Dr Y Nayudamma memorial award, said.
