The Indian Ministry of Science & Technology and Earth Sciences has launched the National Tsunami Early Warning System that has been set up at the Indian National Centre for Ocean lnformation Services (INCOIS), Hyderabad (India).
The Ministry of Earth Sciences (MoES) has established the warning system at a cost of INR 125 crore with the collaboration of Department of Science and Technology (DST), Department of Space (DOS) and the Council of Scientific and Industrial Research (CSIR). The Early Warning Centre receives real-time Seismic data from the national seismic network of the lndian Meteorological Department (IMD) and other International seismic networks. The Indian Tsunami Early Warning System comprises a real-time network of seismic stations, Bottom Pressure Recorders (BPR) and tide gauges to detect tsunamigenic earthquakes and to monitor tsunamis. The system detects all earthquake events of more than 6 Magnitude occurring in the Indian Ocean in the less than 20 minutes of occurrence. BPRs installed in the Deep Ocean are the key sensors to confirm the triggering of a Tsunami. The National Institute of Ocean Technology (NIOT) has installed 4 BPRs in the Bay of Bengal and the 2 BPRs in Arabian Sea. In addition, NIOT and Survey of India (SOI) have installed 30 Tide Gauges to monitor the progress of tsunami waves. A state-of-the-art early warning centre is established at INCOlS with all the necessary computational and communication infrastructure that enables reception of real-time data from all the sensors, analysis of the data, generation and dissemination of tsunami advisories following a standard operating procedure.
