Editorial Analysis: India as a Global Leader in Tsunami Disaster Management

*General Studies-3; Topic: Disaster and disaster management.*

Introduction

• The tsunami of December 26, 2004, which claimed over 230,000 lives across 14 countries, was a turning point in global disaster management.

• For India, this tragedy underscored the urgent need for robust preparedness measures, leading to the establishment of the Indian Tsunami Early Warning System (TEWS).

• Today, India stands as a global leader in tsunami disaster management, with a state-of-the-art warning system that is a model for international cooperation and technological excellence.

Key Features of the Indian Tsunami Early Warning System (TEWS)

• Genesis and Institutional Framework Following the 2004 Indian Ocean tsunami, the Government of India established the Indian Tsunami Early Warning Centre (ITEWC) under the Indian National Centre for Ocean Information Services (INCOIS) in Hyderabad. Operational since 2007, the centre is now central to India’s disaster preparedness and response capabilities.

• Technological Components Seismic Sensors: A network of stations monitors tectonic activity in the Indian Ocean and beyond, providing real-time data on undersea earthquakes. Deep-Ocean Pressure Recorders (DART): These measure changes in ocean pressure that indicate tsunami waves. Wave Rider Buoys: Installed in strategic locations, they track wave parameters to refine tsunami predictions. Tide Gauges: These measure sea-level changes to confirm tsunami events. Satellite Communication Systems: Critical for transmitting data and disseminating alerts swiftly.

India’s Global Role in Tsunami Preparedness

• International Collaboration India’s TEWS integrates data from global seismic networks and collaborates with agencies such as the Pacific Tsunami Warning Center and Japan Meteorological Agency (JMA). Indigenous innovations like the Deep-Ocean Assessment and Reporting of Tsunamis (DART) buoys are pivotal in real-time ocean pressure monitoring.

Challenges and Areas for Improvement

• Evolving Threats Beyond Plate Boundaries: While tsunamis are primarily associated with tectonic plate boundaries, events in the Pacific suggest that they can occur at plate tails due to realignments. The Indian Ocean’s Makran and Sumatra sources require continuous study. Non-Seismic Causes: Tsunamis caused by landslides, meteorite impacts, or nuclear explosions pose unique challenges for prediction.
