Important Days in November 2026<\/a><\/strong><\/p>\nGlobal Frameworks for Tsunami Risk Reduction<\/b><\/h2>\n
International cooperation is essential because tsunamis can cross national boundaries and affect several countries within a short period.<\/span><\/p>\n\n- Sendai Framework for Disaster Risk Reduction (2015\u20132030)<\/b><\/li>\n<\/ol>\n
\n- Adopted at the Third UN World Conference on Disaster Risk Reduction in Sendai, Japan, in 2015.<\/span><\/li>\n
- Provides a global framework to prevent new disaster risks and reduce existing risks.<\/span><\/li>\n
- Emphasises understanding disaster risk, strengthening disaster risk governance, investing in resilience and enhancing preparedness for effective response and recovery.<\/span><\/li>\n
- Its implementation is particularly relevant to strengthening tsunami preparedness and reducing the vulnerability of coastal communities.<\/span><\/li>\n<\/ul>\n
\n- Early Warnings for All (EW4All) Initiative<\/b><\/li>\n<\/ol>\n
\n- Launched by the United Nations in 2022.<\/span><\/li>\n
- Aims to ensure that everyone on Earth is protected by multi-hazard early warning systems.<\/span><\/li>\n
- Focuses on four pillars: disaster risk knowledge, detection and forecasting, warning dissemination and communication, and preparedness to respond.<\/span><\/li>\n
- Highlights the importance of making warnings accessible and ensuring that people know how to act on them.<\/span><\/li>\n<\/ul>\n
\n- UNESCO-IOC Tsunami Ready Programme<\/b><\/li>\n<\/ol>\n
\n- Developed by the Intergovernmental Oceanographic Commission (IOC) of UNESCO to improve tsunami preparedness at the community level.<\/span><\/li>\n
- Promotes cooperation among government agencies, scientists, local authorities and communities.<\/span><\/li>\n
- Uses 12 indicators covering tsunami risk assessment, preparedness and response.<\/span><\/li>\n
- Encourages communities to develop evacuation maps, display warning information, conduct awareness activities and organise regular evacuation exercises.<\/span><\/li>\n<\/ul>\n
The programme provides a voluntary, performance-based recognition framework for communities that demonstrate the required level of preparedness.\u00a0<\/span><\/p>\nIndia\u2019s Tsunami Preparedness<\/b><\/h2>\n
India has a long coastline and several coastal regions exposed to tsunami hazards, particularly those facing the Indian Ocean. The Indian Ocean tsunami of 26 December 2004 caused extensive loss of life and damage across the region, including in India. It highlighted the need for a dedicated tsunami early warning system.<\/span><\/p>\nIndian Tsunami Early Warning System (ITEWS)<\/b><\/p>\n\n- Following the 2004 tsunami, the Government of India established the Indian Tsunami Early Warning Centre (ITEWC) at the Indian National Centre for Ocean Information Services (INCOIS), Hyderabad, under the Ministry of Earth Sciences.<\/span><\/li>\n
- The centre became operational on 15 October 2007 and functions round the clock.<\/span><\/li>\n
- It monitors potential tsunami-generating earthquakes and sea-level changes to issue timely advisories to authorities and vulnerable communities.<\/span><\/li>\n<\/ul>\n
Major components of the system include:<\/b><\/p>\n\n- Seismic stations to detect earthquakes and determine their location and magnitude.<\/span><\/li>\n
- Bottom Pressure Recorders (BPRs) to detect changes in water pressure associated with tsunami waves.<\/span><\/li>\n
- Tide gauges to monitor sea-level changes along the coast.<\/span><\/li>\n
- Numerical models, coastal vulnerability assessments and inundation maps to support tsunami forecasting and evacuation planning.<\/span><\/li>\n
- Communication systems to disseminate warnings and advisories to relevant authorities.<\/span><\/li>\n<\/ul>\n
The centre is also part of the Indian Ocean Tsunami Warning and Mitigation System coordinated by UNESCO-IOC.\u00a0<\/span><\/p>\nChallenges in Tsunami Preparedness<\/b><\/h2>\n
Despite improvements in monitoring and warning technologies, several challenges affect effective tsunami risk reduction.<\/span><\/p>\n\n- Limited public awareness:<\/b> People in coastal areas may not recognise natural warning signs or know the correct evacuation procedures.<\/span><\/li>\n
- Last-mile communication gaps: <\/b>Warnings may not reach remote coastal settlements, fishing communities and tourists in time or in a language they understand.<\/span><\/li>\n
- High coastal exposure: <\/b>Population growth, tourism, ports and infrastructure development in low-lying coastal areas increase the potential impact of tsunamis.<\/span><\/li>\n
- Inadequate evacuation infrastructure:<\/b> Lack of clearly marked routes, safe shelters and accessible evacuation facilities can delay movement to safety.<\/span><\/li>\n
- Vulnerable groups:<\/b> Children, older persons, persons with disabilities and people unfamiliar with local geography may require additional support during evacuation.<\/span><\/li>\n
- Cross-border coordination:<\/b> Tsunamis can affect multiple countries, making timely information-sharing and regional cooperation essential.<\/span><\/li>\n<\/ul>\n
Way Forward<\/strong><\/h2>\n\n- Strengthen community preparedness:<\/b> Conduct regular evacuation drills, public awareness campaigns and school-based preparedness activities.<\/span><\/li>\n
- Improve last-mile warning systems: <\/b>Use multiple communication channels, including mobile alerts, sirens, radio and local networks, to ensure timely dissemination of warnings.<\/span><\/li>\n
- Promote risk-informed coastal planning:<\/b> Use hazard maps and coastal vulnerability assessments to guide infrastructure development and land-use planning.<\/span><\/li>\n
- Ensure inclusive evacuation planning: <\/b>Provide accessible evacuation routes, warning messages and assistance for people who may need additional support.<\/span><\/li>\n
- Strengthen regional cooperation: <\/b>Improve data-sharing, scientific collaboration and coordination among countries bordering the Indian Ocean.<\/span><\/li>\n
- Expand Tsunami Ready communities: <\/b>Encourage local authorities and coastal communities to adopt the UNESCO-IOC preparedness indicators and participate in regular exercises.<\/span><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
