CaribWave17 Logo

A number of CDEMA's Participating States are participating in today's CARIB WAVE 17 Caribbean Tsunami Exercise.


The exercise will simulate a major earthquake and tsunami generated by a hypothetical magnitude 7.9 earthquake located off the Caribbean coast of Costa Rica, a Magnitude 8.2 earthquake located along the southeastern coast of Cuba and a Magnitude 8.5 earthquake along the Northern Lesser Antilles. National Disaster Offices throughout CDEMA's Participating States will undertake various activities ranging from table top, simple orientation to full scale exercises. The purpose of the #CARIBWAVE17 exercise is to evaluate local tsunami response plans, increase tsunami preparedness, and improve coordination throughout the region.
