Components & Working:
A Tsunami Warning Centre operating on 24×7 basis.
A network of land-based seismic stations for earthquake detection.
A network of 12 Bottom Pressure Recorders (that could detect and measure a change in water level of 1 cm at water depths of up to 6 km of water).
A network of tsunami buoy system it measures the change in height of the water column then this water column height is communicated and then relayed via satellite to the tsunami warning center.
Real-time observational network for upper ocean parameters and surface met-ocean parameters.
A network of 50 real time tide gauges, radar- based coastal monitoring stations and current meter moorings to monitor progress of tsunami and storm surges .
The EWS receives real-time Seismic data from the National Seismic Network the system detects all earthquake events of more than 6 Magnitude occurring in the Ocean . BPRs installed in the Deep Ocean and Buoys are the key sensors to confirm the triggering of Tsunami through INSAT end-to-end communication takes place and disseminate alerts to MHA by satellite- based virtual private network (VPN DMS). This network enables early warning center to disseminate warnings to the MHA, as well as to the State Emergency Operations Centers.
