Intergovernmental Coordination Group. As subsidiary bodies of the IOC of UNESCO, the ICG meets to promote, organize, and coordinate regional tsunami mitigation activities, including the issuance of timely tsunami warnings. To achieve this objective requires the participation, cooperation and contribution of many national and international seismic, sea level, communication, and dissemination facilities throughout the region. The ICG is comprised of Member States in the region. Currently, these are ICGs for tsunami warning and mitigation systems in the Pacific, Indian Ocean, Caribbean and adjacent regions, and the north-eastern Atlantic, the Mediterranean and connected seas.
