"We are in talks with Indonesia and Australia to integrate our tsunami warning systems," Earth Sciences Minister Prithviraj Chavan said at a function to release the guidelines for Management of Tsunamis formulated by the National Disaster Management Authority.
Launched three years back, the Indian Tsunami Warning System provides advisories to concerned government departments and to vulnerable communities of an impending disaster.
The system comprises a real-time network of seismic stations, bottom pressure recorders (BPR), tide gauges and 24x7 operational tsunami warning centre to detect tsunamigenic earthquakes and to monitor tsunamis.
Indian scientists and engineers are currently evaluating the Indonesian Tsunami Warning System and exploring ways on how to integrate the two, Shailesh Nayak, Secretary, Ministry of Earth Sciences told PTI.
The Australian system was in an advanced stage of being set up and Indian scientists had held consultations with them.
The system has a dedicated tsunami warning centre operating on 24x7 basis for generation of timely advisories.
It also has a network of land-based seismic stations for earthquake detection and estimation of focal parameters in the two known tsunamigenic zones for real-time communication to the early warning centre.
The system has a network of bottom pressure recorders capable of detecting and measuring a change in water level of 1 cm at water depths of up to 6 km to detect and monitor tsunami around these two tsunamigenic zones.
A network of real time tide gauges, radar-based coastal monitoring stations and current meter moorings have also been set up to monitor progress of tsunami and storm surges.
The Indian and Indonesian warning systems were set up in the aftermath of the devastating tsunami that hit the region in December 2004.
