| Tsunami Warning Centres Overview |
When a major undersea earthquake occurs near the coast and at a shallow depth, there is a possibility that a destructive tsunami can be generated that will impact near-by coasts within minutes and that can also traverse across entire ocean basins to wreak havoc 1000’s of miles away and up to 24 hours later. To alert far-away coasts, internationally-coordinated tsunami early warning systems have been established to provide alerts to countries on regional-to-distant tsunamis.
The mission of a Tsunami Warning Centre (TWC) is to provide early tsunami warnings on potentially destructive tsunamis. It provides this information to emergency officials, and as appropriate, directly to the public.

| Pacific Tsunami Warning |
The Pacific Tsunami Warning and Mitigation System (TWS) is coordinated through the UNESCO IOC’s Intergovernmental Co-ordination Group for the Pacific Tsunami Warning and Mitigation System (ICG/PTWS). One of its most important activities is ensure the timely issuance of tsunami warnings and advisories. The Pacific TWS provides international warning advisories to countries that have officially designated Tsunami Warning Focal Points (TWFP). Its primary objective is to continuously detect and locate major earthquakes in the Pacific region, determine whether they have generated tsunamis, and provide timely and effective tsunami information and warnings to coastal communities in the Pacific to minimize the hazards of tsunamis, especially to human life and welfare.

| Caribbean Tsunami Watch |
In order to take steps to establish a coordinated early warning system for tsunamis and other coastal hazards, countries of the Caribbean region formed the Intergovernmental Coordination Group for the Tsunami and Other Coastal Hazards Warning System for the Caribbean Sea and Adjacent Regions (ICG/CARIBE-EWS) in 2006. At that time, it will realized that it would likely be some time before the required infrastructure could be put in place, training was complete, and the region able to fully provide warning services for itself.

| Indian Ocean Tsunami Watch |
Since April 2005, based on discussions that began at the United Nations World Conference on Disaster Reduction (WCDR) held in Kobe, Japan, 18-22 January 2005, the US NOAA Pacific Tsunami Warning Center (PTWC) in cooperation with the Japan Meteorological Agency (JMA) have been providing limited early warning services to the Indian Ocean region. This was an urgent outcome of the WCDR Regional/Thematic Special Session “Promotion of tsunami disaster mitigation in the Indian Ocean,” wherein the existing telecommunication tools and seismic and sea-level data were to be used by the Pacific Ocean centers (PTWC and JMA) to provide interim alerts until center(s) of the Indian Ocean region were able to issue their own “Tsunami Warnings.” Because of the availability of data, only Tsunami Watch Information advise is issued by the international centers.
