Caribe Wave 2022 (March 10)

The exercise guidelines, other related materials and links for registration and evaluation are available at

Who organizes CARIBE WAVE 22?

A CARIBE EWS CARIBE WAVE task team is responsible for the overall conduct of the exercise. The NOAA/UNESCO IOC International Tsunami Information Center Caribbean Office serves as exercise coordinator with the Caribbean Tsunami Information Center. Regional emergency management stakeholders (CEPREDENAC [Coordination Centre for the Prevention of Natural Disasters in Central America], CDEMA [Caribbean Disaster Emergency Management Agency], and EMIZA [French Inter-Ministerial for the Antilles Estate Major Zone]) also contribute to the successful conduct of the exercise.


What is the purpose of CARIBE WAVE 2022?

The purpose of this exercise is to validate and advance tsunami preparedness efforts in the Caribbean and Adjacent Regions.

When is CARIBE WAVE 2022?

The annual Tsunami Regional Exercise, CARIBE WAVE 2022, will take place on March 10, 2022, starting at 1400 UTC. You can register here.

Which scenario will be used for CARIBE WAVE 2022?

Two different scenarios will be simulated for CARIBE WAVE 2022. Each participating country will select the scenario that best fits their objectives. The first scenario simulates a tsunami generated by a magnitude 8.0 earthquake located on the Western Muertos Trough. The second scenario simulates a magnitude 8.3 earthquake and tsunami along the North Panama Deformed Belt.

Why should I participate in this exercise each year?

High levels of vulnerability and risk to life and livelihoods from tsunamis along the coasts of the Caribbean and Adjacent Regions should provide a strong incentive for countries and local jurisdictions to prepare for a tsunami and participate in this exercise. Given the pandemic, emergency response plans have been adapted and this is a good opportunity to review and test these new procedures.

What communication systems are tested in this exercise?

The communications between the Pacific Tsunami Warning Center (PTWC) and the Tsunami Warning Focal Points (TWFPs) and National Tsunami Warning Centres (NTWC) will be tested. Each country and territory decide if and how messages are disseminated within its area of responsibility.

Which agencies participate in this exercise?

Each one of the 48 countries and territories that are members of CARIBE EWS decide on the level of participation and coordinate the corresponding activities within their jurisdiction. All officially designated CARIBE EWS National Tsunami Warning Focal Points and Warning Centers will receive products from the PTWC.

How does the COVID-19 pandemic affect the exercise?

COVID-19 safety measures will still be in effect and need to be considered during planning. Participation by the public does not need to be in person, but activities like checking emergency plan/tsunami route/supplies can be encouraged.
