UNESCO’s Call for Enhanced Tsunami Preparedness

The 2024 international conference in Banda Aceh marked 20 years since the catastrophic 2004 Indian Ocean tsunami. In response, the United Nations Educational, Scientific and Cultural Organization (UNESCO) has emphasised the urgent need for improved global tsunami preparedness. The conference brought together experts and policymakers to discuss strategies for achieving 100 tsunami-ready coastal communities by 2030.

Global Tsunami Preparedness Progress

Since the 2004 disaster, which resulted in over 227,000 deaths, UNESCO has led initiatives to enhance tsunami preparedness. The Tsunami Ready programme has benefitted more than 30 countries. These efforts have established critical early warning systems. However, the increasing coastal population, projected to reach 1 billion by 2050, necessitates further action.

Challenges Ahead

Despite progress, important challenges remain. Currently, 700 million people live in tsunami-prone areas. Local tsunamis occur in the Pacific every 1-2 years. The Mediterranean faces a near 100% chance of a tsunami in the next three decades. These statistics highlight the need for sustained investment in tsunami preparedness.

Three-Step Warning Process

UNESCO’s effective tsunami warning system relies on a three-step process: 1. Detection – Utilising advanced monitoring systems like seismic sensors and deep-ocean buoys to swiftly identify disturbances. 2. Warning – Forecasting wave propagation and potential impacts, followed by immediate alerts. 3. Dissemination – Ensuring rapid communication to vulnerable populations through sirens, radio, and smartphones. This approach is critical for timely response and minimising casualties.

Recent Developments and Initiatives

The conference acknowledged new Tsunami Ready communities, including 26 in India and 12 in Indonesia. Real-time drills conducted near Banda Aceh tested community preparedness. These exercises reinforced the necessity of effective warning systems and community readiness. UNESCO aims to provide tsunami confirmation within 10 minutes or less for high-risk coastlines by 2030. This commitment marks the organisation’s dedication to safeguarding lives and reducing disaster impacts.

Investment and Commitment

UNESCO’s Director-General, Audrey Azoulay, stressed the importance of continued investments by Member States. Strengthening tsunami preparedness requires collective action from governments and civil society. The Banda Aceh Statement reflects a global commitment to enhancing tsunami warning and mitigation systems.
