India will now know about natural calamities like tsunami and earthquake in advance. India is working on a big plan for this. Under this, a smart sensor is being made, which will develop an underwater tsunami and earthquake early warning system with a 275 km long cable in the Indian Ocean. According to the Times of India report, if this system is successful, it will change the way of detecting seismic activity, submarine landslides and deep sea danger.
According to the report, this plan is currently in the stage of request for proposal. Hyderabad's Indian National Ocean Information Service Center (INCOIS) is working on this. INCOIS Director TM Balakrishnan Nair says that currently this area is monitored by tsunami buoys, but the data is sent to the Indian Tsunami Early Warning Center in INCOIS. Nair says that maintaining the buoys is challenging, so this system will be more reliable.
How will the smart sensor work?
The underwater sensor-equipped communication cable will be laid from the Andaman Islands to the seismically active Andaman-Nicobar subduction zone in the Indian Ocean at a depth of 2,500 metres. The cable will have a set of sensors comprising bottom pressure recorders, seismometers, tilt meters and hydrophones to monitor seismic activity, undersea landslides and sudden pressure changes. A coastal station will also be built in the Andaman Islands and the communication cable will connect to a data processing centre in Hyderabad for alerts.
