With a sharp and advance forecasting of a possible tsunami, the scientists of Hyderabad's Indian Tsunami Early Warning Centre (ITEWC) alerted the 28 countries.
Dr Satish Shenoi, director, Indian National Centre for Ocean Information Services (INCOIS) said, "There were minor tsunami waves following the earthquake but they subsided within minutes. We withdrew the alert once we were sure that there was no possibility of any tsunami."
According to sources, scientists in Hyderabad’s INCOIS and Chennai’s National Institute of Ocean Technology, who developed the tsunami buoys and bottom pressure recorders, detected the changes in sea surface and bottom temperature, pressure, wind speed and direction for the first time on Wednesday.
The team, without wasting any time, informed ITEWC about their findings and ITEWC issued the tsunami warnings, though it did not hit the world.
