UPSC Editorial Analysis: India’s Tsunami Preparedness
Kartavya Desk Staff
*General Studies-3; Topic: Disaster and disaster management.*
Introduction
• The 2004 Indian Ocean tsunami (killing over 2.3 lakh people in 14 countries) was a watershed moment in disaster management.
• For India, it highlighted the urgent need for preparedness and early warning systems.
• The result was the Indian Tsunami Early Warning System (TEWS), making India a global model for technological excellence and regional cooperation.
Indian Tsunami Early Warning System (TEWS) – Key Features
• Genesis and Institutional Setup
• Post-2004, India set up the Indian Tsunami Early Warning Centre (ITEWC) under INCOIS, Hyderabad. Fully operational since 2007, it is central to India’s disaster response strategy.

• Core Technological Components
• Seismic Sensors → detect undersea earthquakes. DART Buoys → measure ocean pressure for tsunami wave detection. Wave Rider Buoys → track wave behaviour. Tide Gauges → confirm abnormal sea-level rise. Satellite Communication Systems → enable rapid transmission of data and alerts.

India’s Global Role in Tsunami Preparedness
• International Collaboration
• Shares data with global seismic networks and collaborates with Pacific Tsunami Warning Center and Japan Meteorological Agency. Indigenous innovations like DART buoys enhance reliability.

• Indigenous innovations like DART buoys enhance reliability.
• Regional Support
• As a UNESCO Regional Tsunami Service Provider, India provides advisories to 25 Indian Ocean Rim countries. Its successful forecasts during events like the 2012 Banda Aceh earthquake proved its efficiency.

• Global Comparison
• Japan – most advanced TEWS due to high seismic activity. US (NOAA) – monitors Pacific and Atlantic coasts. Indonesia & Chile – focus on high seismic zones. Australia & New Zealand – ensure safety in the Indian and Pacific Oceans.

Challenges Ahead
• Evolving Threats – Tsunamis from Makran coast or plate tail realignments need more study.
• Non-seismic causes – Landslides, meteorite impacts, even nuclear tests pose new risks.
• Precursors underutilized – Ocean withdrawal, animal behavior, unusual sounds/odors could aid early response.
• Public Awareness Gaps – Last-mile connectivity, community drills, and citizen participation remain weak.
• Climate Change – Rising sea levels and coastal vulnerabilities demand integrated adaptation strategies.
Way Forward
• Research & Development Invest in understanding non-seismic tsunami triggers. Develop AI-driven predictive models.
