Caribe Wave 2021

Caribe Wave 2021

CARIBE WAVE is the annual tsunami exercise of the Intergovernmental Oceanographic Commission (IOC) of the United Nations Educational, Scientific, and Cultural Organization (UNESCO). In 2021, the exercise will be conducted on 11 March, 10th year of the Tohoku, Japan earthquake and tsunami. It is coordinated together with the U.S. National Oceanic and Atmospheric Administration (NOAA) and the Caribbean 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]). The purpose of this exercise each year is to advance tsunami preparedness efforts in the Caribbean and Adjacent Regions.

When is CARIBE WAVE 2021?

The annual Tsunami Regional Exercise, Caribe Wave 2021, will take place on March 11, 2021, starting at 1400 UTC. You can register here.

Which scenario will be used for CARIBE WAVE 2021?

In Caribe Wave 2021 two different scenarios will be simulated. Each participating country will select the scenario that fits their objectives. The first scenario simulates a tsunami generated by a magnitude 8.0 earthquake located on the Enriquillo-Plantain Garden Fault Zone in Jamaica. The second scenario simulates a magnitude 8.5 earthquake and tsunami along the subduction zone in the Northern Lesser Antilles.

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 decides 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.

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.
