Map and Directions to ITIC


Located in Honolulu, the International Tsunami Information Centre (ITIC) was established Resolution IV-6 in November 1965 by the Intergovernmental Oceanographic Commission (IOC) of the United Nations Educational, Scientific and Cultural Organization (UNESCO). It is hosted by the US National Oceanic and Atmospheric Administration National Weater Service, who provides the Director and office staff in Honolulu, Hawaii.  Since 1998, Chileʻs Naval Hydrographic and Oceanographic Service (Servicio Hidrográfico y Oceanográfico de la Armada de Chile) has provided the Associate Director.  ITICʻs mandate and functions in support of Member States of the Intergovernmeantl Coordination Group for the Pacific Tsunami Warning and Mitigation System (ICG/PTWS, formerly ITSU) were approved by IOC Resolution X-23 (1977).  ITIC maintains and develops relationships with scientific research and academic organizations, civil defense agencies, and the general public in order to carry out its mission to mitigate the hazards associated with tsunamis by improving tsunami preparedness for all Pacific Ocean nations.  ITIC is also assisting in the development and implementation of tsunami warning and mitigation systems globally (IOC Resolutions XXIII-12, 13, and 14 (Indian, Caribbean, and Mediterranean respectively,2005).

The ITIC's responsibilities include:

  • monitoring the international tsunami warning activities in the Pacific and other oceans and recommending improvements in communications, data networks, acquisition and processing, tsunami forecasting methods, and information dissemination;
  • bringing to Member and non-member States information on tsunami warning systems, on the affairs of IOC and ITIC, and on how to become active participants in the ICG/PTWS;
  • assisting Member States in the establishment of national and regional warning systems, and the reduction of tsunami risk through comprehensive mitigation programmes;
  • acting as a clearinghouse for the development of educational and preparedness materials, event data collection, and the fostering research and its application to prevent loss of life
