India’s Tsunami Early Warning System

Upgrading the Tsunami Early Warning System is crucial in the context of climate change, increasing marine hazards, and technological advancements.

Key Aspects of the Tsunami Early Warning System Upgrade

Advanced Sensors and Monitoring Systems

  • Deep-Ocean Sensors (DART): Pressure sensors on the ocean floor (Deep-ocean Assessment and Reporting of Tsunamis) that detect early tsunami waves.
  • Satellite Monitoring: Use of satellites (such as INSAT, Oceansat) to track changes on the ocean surface.
  • Seismic Sensors: Advanced seismographs for rapid detection of earthquake activity.
  • Upgrades: Expansion of sensor networks for real-time data transmission, higher sensitivity, and wider coverage.
  • Example: India has increased the number of DART buoys ....
