The Fifth Session of the ICG/CARIBE EWS held in Managua, Nicaragua, 15–17 March 2010 decided to conduct a joint CARIBE Wave 2011 and LANTEX 2011 exercise.  This was the inaugural regional exercise and variations have been conducted since 2011 with the regional tsunami exercise has now become an annual event on the tsunami preparedness calendar within the Caribbean and its adjacent regions.

Events, such as the 2004 Indian Ocean, 2009 Samoa, 2010 Haiti and Chile, and the 2011 Japan earthquakes and tsunamis, attest to the importance of proper planning for tsunami response. The purpose of the exercise is to improve Tsunami Warning System effectiveness along the Caribbean coasts. The exercise provides an opportunity for emergency management organizations throughout the Caribbean to exercise their operational lines of communications, review their tsunami response procedures, and promote tsunami preparedness. Regular exercising of response plans is critical to maintain readiness for an emergency. This is particularly true for tsunamis, which are infrequent but high impact events. Every Caribbean emergency management organization (EMO) is encouraged to participate. 

Regional organisations including the ICG/CARIBE-EWS and its Secretariat, CTIC, CTWP, the Coordination Centre for Prevention of Natural Disasters in Central America (CEPREDENAC), CDEMA, NOAA, and the U.S. National Tsunami Hazard Mitigation Program (NTHMP), EMIZ Antilles  contribute to planning and execution of the exercise.
