Produced by the Intergovernmental Oceanographic Commission of UNESCO (update Feb 2020).
The UNESCO Intergovernmental Oceanographic Commission (IOC) has been mandated to facilitate the coordination of the international tsunami warning and mitigation system. The 1st system was established in the Pacific in 1965 in response to the M9.5 Chile earthquake and tsunami (Intergovernmental Coordination Group for the
Pacific Tsunami Warning and Mitigation System). After the 2004 Indian Ocean tsunami, the IOC established systems in 2005 for the
Indian Ocean,
Caribbean, and
NE Atlantic and Mediterranean. The systems are owned and operations by IOC Member States, with Regional Tsunami Service Providers providing threat information and guidance to Member States. Member States of each region meet regularly to review progress and coordinate activities resulting in improvements of the services.
