This Strategy outlines key objectives for a continuously improving North-eastern Atlantic,

Mediterranean and connected seas Tsunami Warning System (NEAMTWS) to meet stakeholder requirements during the period 2021–2030. It will also contribute to the UN Decade of Ocean Science for Sustainable Development 2021–2030, in particular by responding to the needs of society for a “safe ocean where people are protected from ocean hazards. In particular, it will contribute to the UN Ocean Decade Tsunami Programme Research and Development Implementation Plan to be considered for endorsement by the IOC Assembly at its 32nd Session in 2023. In turn, the Strategy seeks to capitalise on the Ocean Decade societal benefits in order to further improve monitoring, detection and data-sharing among Member States and partners. The Strategy replaces the outdated NEAMTWS Implementation Plan (IOC Technical Series, 73;2007) and is supported by Annual Plans of Action that specify in more detail the measurable and time-bound actions planned by the Working Groups and Task Teams of the NEAMTWS Intergovernmental Coordination Group.
