Strengthening Coastal Resilience: India’s Preparedness for Tsunami Disaster Risk Mitigation

As the global community observes World Tsunami Awareness Day on November 5, 2026, the theme 'Be Tsunami Ready: Resilience starts with you' shifts the focus from purely structural mitigation to individual and community-level preparedness. For a country like India, with a vast coastline spanning over 7,500 kilometers, the risk posed by the subduction zones in the Indian Ocean—specifically the Makran and Andaman-Sumatra trenches—necessitates a proactive disaster management strategy.

While the Indian Tsunami Early Warning Centre (ITEWC) has established a world-class monitoring network capable of disseminating warnings within minutes, the 'last-mile' connectivity remains the most significant challenge in disaster risk reduction (DRR). The 2026 observance underscores that early warning systems are only as effective as the community's ability to interpret and act upon them. Institutional preparedness, including the implementation of the Tsunami Ready recognition programme initiated by the Intergovernmental Oceanographic Commission (IOC-UNESCO), is essential for ensuring that coastal habitations are equipped with evacuation plans, signages, and regular drills.

Furthermore, the integration of traditional knowledge with modern technology is becoming paramount. As urban coastal clusters expand due to rapid development and industrialization, the risk profile of these regions changes significantly. Policymakers must focus on hazard-resilient infrastructure (such as bio-shields like mangroves) and the enforcement of Coastal Regulation Zone (CRZ) norms to mitigate the impact of surge events. The current emphasis on 'resilience starting with you' implies a shift toward decentralized disaster governance, where local bodies and NGOs play an active role in awareness campaigns, ensuring that the marginalized populations—often the most vulnerable to geophysical shocks—are not left behind in the event of a disaster.
