- The Indian National Centre for Ocean Information Services (INCOIS) has the mandate of detecting tsunamigenic earthquakes occurring in the Indian Ocean as well as in the Global Oceans within 10 minutes of the occurrence of the earthquake and disseminating the tsunami related advisories to the concerned authorities through email, fax, SMS, GTS and website.
- The India Tsunami Early Warning Centre (ITEWC) established at INCOIS Hyderabad, has the latest scientific techniques to provide early warnings for an impending tsunami to all countries in the Indian Ocean region.
- Intergovernmental Oceanographic Commission (IOC) of UNESCO has designated ITEWC as the Tsunami Service Provider (TSP) for the entire Indian Ocean Region.
- Since 2012, ITEWC is providing tsunami advisories and related services to about 25 countries.
- Indian Tsunami Early Warning System comprises a real-time seismic monitoring network of broadband seismic stations.
- INCOIS also has a real-time sea-level network with 7 tsunami buoys in the open ocean and 35 tide gauges at different locations on the coast to monitor the tsunami waves.
- In addition, INCOIS also takes the help of numerical model to assess the tsunami potential at different locations on the coast.
- ITEWC is also receiving data in real time from 350 seismic stations, 50 tsunami buoys and 300 tide gauges established in the Indian as well as the other oceans by other countries and international agencies.
- ESSO-INCOIS was established as an autonomous body in 1999 under the Ministry of Earth Sciences (MoES) and is a unit of the Earth System Science Organization (ESSO).
- It is situated in Hyderabad.
- ESSO- INCOIS is mandated to provide the best possible ocean information and advisory services to society, industry, government agencies and the scientific community through sustained ocean observations and constant improvements through systematic and focussed research.
