General Outline of the Exercise

For the CARIBE WAVE 2024 Regional Exercise, two scenarios have been proposed for the participants: the Puerto Rico Trench Scenario and the Panamá Scenario. The participants in the Puerto Rico and Virgin Islands Region (Puerto Rico, the US Virgin Islands, and the British Virgin Islands) may use the Puerto Rico Trench Scenario as an agreement for their region.

The Puerto Rico Scenario will simulate a tsunami generated by an 8.7 Mw local earthquake located at 86.6 km North of Manatí (Puerto Rico) at a latitude of 19.28°N and longitude of 66.5°W.

For this CARIBE WAVE 2024 Communication Exercise, the scenario is based on tsunami observations related to the tsunami generated by a local earthquake at the Puerto Rico Trench.  For Puerto Rico and the Virgin Islands Region, a tsunami located at the North of Puerto Rico island is considered a local tsunami.  The tsunami scenario used for Puerto Rico and the Virgin Islands, based on this exercise, is as follows:

Origin Time15:00:00 UTC March 21, 2024
Latitude19.25º N
Longitude66.5º W
Depth20 km
Magnitude8.7 Mw

In a real situation, for an event like this one, a tsunami warning/advisory/watch, could last many more hours than those proposed in this exercise.  This exercise has been adapted to be concluded in a compressed time.

Exercise Purpose

The purpose of the exercise is to improve Tsunami Warning System effectiveness in the Caribbean and adjacent regions. The exercise provides an opportunity for emergency management organizations throughout the region 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 the Caribbean and adjacent regions, where tsunamis are infrequent but can be of very high impact. Every emergency management organization (EMO) is encouraged to participate.

Exercise Objectives

Each organization can develop its objectives for the exercise depending on its level of involvement in the scenario. The following are the exercise’s overarching objectives to exercise and evaluate operations of the CARIBE-EWS Tsunami Warning System.

  • Exercise and evaluate communications between the regional TSP and Members States/Territories.
    • Validate the issuance of tsunami products from the PTWC
    • Validate the receipt of tsunami products by CARIBE-EWS TWFPs and/or NTWCs.
  • Evaluate the tsunami procedures and programmes within Members States/Territories.
    • Validate readiness to respond to a tsunami.
    • Validate the operational readiness of the TWFPs/NTWCs and/or the National Disaster Management Office (NDMO).
    • Improve operational readiness. Before the exercise, ensure appropriate tools and response plan(s) have been developed, including public education materials
    • Validate that the dissemination of warnings and information/advice by TWFPs and NTWCs to relevant in-country agencies and the public is accurate and timely.
    • Evaluate the status of the implementation of the Tsunami Ready program.

Types of Exercises

Exercises stimulate the development, training, testing, and evaluation of Disaster Plans and Standard Operating Procedures (SOPs). Most countries in the region have participated in SOPs workshops in 2013, 2014, 2015 and 2017, and may consider using the materials and expertise acquired to help guide exercise preparation and conduct. Exercise participants may use their own past multi-hazard drills (e.g. flood, hurricane, tsunami, earthquake, etc.) as a framework to conduct CARIBE WAVE 23.

The exercises can be conducted at various scales of magnitude and sophistication.  The following are examples of types of exercises conducted by EMOs:

  • Orientation/Seminar:

An Orientation Exercise lays the groundwork for a comprehensive exercise programme. It is a planned event, developed to bring together individuals and officials with a role or interest in multi-hazard response planning, problem solving, development of SOPs, and resource integration and coordination. An Orientation Exercise will have a specific goal and written objectives and result in an agreed upon Plan of Action.

  • Drill:

The Drill is a planned activity that tests, develops, and/or maintains skills in a single or limited emergency response procedure. Drills generally involve operational response of single departments or agencies. Drills can involve internal notifications and/or field activities.

  • Tabletop Exercise:

The Tabletop Exercise is a planned activity in which local officials, key staff, and organizations with disaster management responsibilities are presented with simulated emergency situations. It is usually informal, in a conference room
environment, and is designed to elicit constructive discussion from participants. Participants will examine and attempt to resolve problems, based on plans and procedures, if they exist. Individuals are encouraged to discuss decisions in depth with an emphasis on slow-paced problem solving, rather than rapid, real time decisionmaking. A Tabletop Exercise should have specific goals, objectives, and a scenario narrative.

  • Functional Exercise:

A Functional Exercise is a planned activity designed to test and evaluate organizational capacities. It is also utilized to evaluate the capability of a community’s emergency management system by testing the Emergency Operations
Plan (EOP). It is based on a simulation of a realistic emergency that includes a description of the situation (narrative) with communications between players and simulators. The Functional Exercise gives the players (decision-makers) a fully simulated experience of being in a major disaster event. It should take place at the appropriate coordination location (i.e. emergency operations centre, emergency command centre, command post, master control centre, etc.) and involve all the appropriate members designated by the plan. Both internal and external agencies (government, private sector, and volunteer agencies) should be involved. It requires players, controllers, simulators, and evaluators. Message traffic will be simulated and inserted by the control team for player response/actions, under real time constraints. It may or may not include public evacuations. A Functional Exercise should have specific goals, objectives, and a scenario narrative.

  • Full-scale Exercise:

A Full-scale Exercise is the culmination of a progressive exercise programme that has grown with the capacity of the community to conduct exercises. A Full-Scale Exercise is a planned activity in a “challenging” environment that encompasses a majority of the emergency management functions. This type of exercise involves the actual mobilization and deployment of the appropriate personnel and resources needed to demonstrate operational capabilities. EOCs and other command centres are required to be activated. A Full-scale Exercise is the largest, costliest, and most complex exercise type. It may or may not include public evacuations.
