It was planned long before the earthquake-turned-tsunami event in Japan to test the readiness of 33 Caribbean countries in the region's first full-scale tsunami warning exercise. On Wednesday, March 23, a fictitious earthquake of 7.6 magnitude occurred off the coast of the U.S. Virgin Islands. Bulletins were issued by the West Coast/Alaska Tsunami Warning Center for Puerto Rico and the Virgin Island and by the Pacific Tsunami Warning Center in Ewa Beach, Hawaii for the rest of the area and the test was underway.

The Caribbean tsunami test, named Caribe Wave 11 did not involve communities but aimed to test the effectiveness of alert, monitoring and warning systems among all the emergency management organizations throughout the region. The test was designed to determine whether Caribbean countries are ready to respond in the event of a dangerous tsunami. Results will be reported in April.

"The earthquake and tsunami that have devastated Japan have shown how essential alert systems are," said Irina Bokova, UNESCO's director general.

The countries that attended the tsunami alert exercise are: Aruba, Antigua and Barbuda, Bahamas, Barbados, Belize, Bolivarian Republic of Venezuela, Brazil, Canada, Colombia, Costa Rica, Cuba, Dominican Republic, France (Martinique, Guadeloupe, St. Martin, Guyane), Grenada, Guatemala, Guyana, Haiti, Honduras, Jamaica, Mexico, Netherlands (Bonaire, Saba, Sint Eustatius, Curacao and Sint Marteen), Nicaragua, Panama, Peru, St. Lucia, St. Vincent and the Grenadines, Sri Lanka, Suriname, Trinidad and Tobago, United Kingdom (Anguilla, British Virgin Islands, Bermuda, Cayman Islands, Montserrat, Turks and Caicos), and the United States.

Over the past 500 years, there have been 75 tsunamis in the Caribbean, which is about 10 percent of the world total during that period, according to the National Oceanographic and Atmospheric Administration (NOAA).

Tsunamis caused by earthquakes, landslides or volcanoes have caused 3,5000 deaths in the region since the mid-1800s
