General Outline

For the CARIBE WAVE 2018 Exercise, three scenarios have been proposed for the participants: the Barbados Scenario, Colombia Scenario and Puerto Rico Scenario.  In the first scenario the tsunami is generated by an earthquake on the Southeast of Barbados, in the second scenario the tsunami is generated by and earthquake in North of Colombia and the third scenario is a tsunami generated by an earthquake West of Puerto Rico. The participants may choose the scenario they want to participate according to the needs of their region or agency. The Puerto Rico and the (U.S. and British) Virgin Islands will use the Puerto Rico Scenario as agreed with the PRSN.  The participant guides (o.02f\ficial manual and PRSN Guidebook) are the basic tools for participation in the CARIBE WAVE 2018 Exercise.

For this CARIBE WAVE 2018 exercise, the scenario is based on earthquakes and tsunamis that occurred in Puerto Rico on October of 1918.  This earthquake had estimated magnitudes between M 7.3 and produced a tsunami with height of 6.1 m (20 ft) on the western coast of Puerto Rico.  For Puerto Rico and Virgin Islands an earthquake with epicenter at the Mona Canyon, west coast of Puerto Rico, is considered a local earthquake. The earthquake scenario used for Puerto Rico and Virgin Islands, based on this exercise, is as follows:

The tsunami models were computed using the Rapid Inundation Forecasting of Tsunamis (RIFT) model to generate expected impacts throughout the region.  The models indicate that a several meters high tsunami will occur affecting both Puerto Rico and the Virgin Islands.

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

Earthquake Scenario

For this CARIBE WAVE 2018 exercise, the scenario is based on earthquakes and tsunamis that occurred in Puerto Rico on October of 1918. This earthquake had estimated magnitudes between M 7.3 and produced a tsunami with height of 6.1 m (20 ft) on the western coast of Puerto Rico. For Puerto Rico and Virgin Islands an earthquake with epicenter at the Mona Canyon, west coast of Puerto Rico, is considered a local earthquake. The earthquake scenario used for Puerto Rico and Virgin Islands, based on this exercise, is as follows:

Earthquake:  Puerto Rico Scenario

Origin Time: 14:00 UTC, March 15, 2018 (10:00 AM Puerto Rico Local Time)

Hypocenter: Latitude: 18.30°N and Longitude: 67.8°W

Depth:           10 km

Magnitude:   7.6 Mw

Location:     West of Rincón, Puerto Rico

The Shake Map for the Puerto Rico Scenario and the Prompt Assessment of Global Earthquakes for Response (PAGER) of the US Geological Survey are available in the IOC Participant Handbook.

 

The Puerto Rico and the (U.S. and British) Virgin Islands participants will use the Puerto Rico Scenario as agreed with the PRSN and should refer to the CARIBE WAVE 2018 PRSN Response Guidebook for the Puerto Rico and Virgin Islands Region.

CARIBE WAVE helps prove that the evacuation plan for a tsunami in your town is a viable one and covers all the necessities during and after an emergency.

The TsunamiReady program was created by the NWS-NOAA to help communities be better prepared to save lives and reduce the damage caused by the occurrence of a tsunami.

Tsunami Scenario

For this CARIBE WAVE 2018 exercise, the scenario is based on earthquakes and tsunamis that occurred in Puerto Rico on October of 1918.  This earthquake had estimated magnitudes between M 7.3 and produced a tsunami with height of 6.1 m (20 ft) on the western coast of Puerto Rico.  For Puerto Rico and Virgin Islands an earthquake with epicenter at the Mona Canyon, west coast of Puerto Rico, is considered a local earthquake.  The earthquake scenario used for Puerto Rico and Virgin Islands, based on this exercise, is as follows:

 

Tsunami generated by a great earthquake of magnitude 7.6 Mw with epicenter in the West of Rincón (latitude 18.30 ° N and longitude 67.8 ° W), at 10:00 am (Puerto Rico Local Time) on March 15, 2018.

 

Participants of Puerto Rico, US Virgin Islands and British Virgin Islands should refer to the information on this webpage based on the PTWC domestic products and the CARIBE WAVE 2018 PRSN Response Guidebook for the Puerto Rico and Virgin Islands Region.  The initial alert is disseminated at 10:06 AM (local time in Puerto Rico) as indicated in Table 1, Exercise Time Table for Puerto Rico and Virgin Islands for the Puerto Rico Scenario.

 

The initial dummy messages will be disseminated over all their standard broadcast channels.  The dummy messages are issued to test communications with Tsunami Warning Focal Points and National Tsunami Warning Centers, and to start the CARIBE WAVE 2018 exercise.  All messages will be sent to the recipients on the special email list used to transmit real messages in real time.

Exercise Purpose

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 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.
  1.  Validate the issuance of tsunami products from the PTWC
  2.  Validate the receipt of tsunami products by CARIBE EWS Tsunami Warning Focal Points (TWFPs) and/or National Tsunami Warning Centers NTWCs)
  • To evaluate the use of PTWC CARIBE EWS products.
  1. Validate readiness to respond to tsunami.
  2. Validate the operational readiness of the TWFPs/ NTWCs and/or the National Disaster Management Office (NDMO).
  3. Improve operational readiness. Before the exercise, ensure appropriate tools and response plan(s) have been developed, including public education materials.
  4. 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.
  5. Evaluate the status of the implementation of the pilot CARIBE EWS Tsunami Ready recognition program.

Types of Exercises

 

The exercise should be carried out such that communications and decision making at various organizational levels are exercised and conducted without alarming the general public. Offices of Emergency Management (OEM) are, however, encouraged to exercise down to the level of testing local notification systems such as the Emergency Alert System (EAS), sirens, or loudspeakers.

Exercises stimulate the development, training, testing, and evaluation of Disaster Plans and Standard Operating Procedures (SOP). Most countries in the region have participated in SOP workshops in 2013 and 2014, and should use the materials and expertise acquired to help guide exercise preparation and conduct. Annex A gives an overview of SOPs. Exercise participants may use their own past multi-hazard drills (e.g. flood, hurricane, tsunami, earthquake, etc.) as a framework to conduct CARIBE WAVE 18.

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

  1. Orientation Exercise (Seminar):

An Orientation Exercise lays the groundwork for a comprehensive exercise program. 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 standard operational procedures (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.

 

  1. 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.

 

  1. 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 the 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 emphasis on slow-paced problem solving, rather than rapid, real time decision-making. A Tabletop Exercise should have specific goals, objectives, and a scenario narrative (see Annex B for a Sample Tabletop Exercise Outline).

 

  1. 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 situation 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 center, emergency command center, command post, master control center, 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.

 

  1. Full-scale Exercise:

A Full-scale Exercise is the culmination of a progressive exercise program 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 centers 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.
