For your safety, if you feel a very strong earthquake, observe a sudden rise or fall in sea level or a tsunami warning is issued:

Protect yourself. During an earthquake find the safest place: drop, cover and hold. When the strong ground shaking ends, a drastic change in sea level occurs or a warning is issued, activate your emergency plan immediately.

Move immediately inland or to a high place out of the danger zone. Although not all earthquakes cause tsunamis, generate tsunamis, a strong local earthquake should be taken as a tsunami warning.

Go on foot if at all possible. You may find traffic jams or roads that have been blocked.

Go to the Assembly Point (A). The official assembly points are marked with an “A” on the map. They have been designated by the Emergency Management authorities, as they are located outside the flooding area, are accessible to the community and have the capacity to host the expected amount of people. You may go to other places as long as they are out of the flooding area.

What should you know and do in case of a tsunami?
A Tsunami is a series of waves generated by a large impulsive displacement of water due to an undersea earthquake, volcanic eruption, landslide or meteorite impact . In deep waters they can travel as fast as 500 miles per hour, equivalent to the speed of a commercial jet. When the tsunami approaches the coast, its speed decreases drastically as well as the distance between the waves, causing it’s height to increase up to dozens of feet.
Puerto Rico has been affected by tsunamis in the past and could be affected again at any moment. In 1867 , an earthquake of magnitude 7.3 with its epicenter in the Virgin Islands generated a tsunami with wave heights of approximately 20 feet in the Virgin Islands and up to 5 feet in eastern Puerto Rico. In 1918 , an earthquake of magnitude 7.3 with its epicenter in Mona Canyon generated a tsunami that reached 20 feet in western Puerto Rico. In 1946 the water receded in western Puerto Rico as a result of a tsunami generated by an earthquake in the Dominican Republic.
In 2003, research was undertaken to evaluate all the potential faults in the region and their capacity to generate tsunamis. Based on these findings, tsunami inundation maps were created, showing, for the worst case scenario, the furthest inland a tsunami could reach in case of a local earthquake. These maps were used as the basis for this evacuation map.
For both local, regional and distant tsunamis, remember to:
Watch out for changes in sea level. Sometimes, the arrival of a tsunami is preceded by a sudden change of sea level. This is the natural warning sign of a tsunami, and should be taken as such immediately.
Remain alert for an emergency. A tsunami protocol exists for Puerto Rico. Information, advisory, warning and “all clear” messages will be issued depending on the situation.
Don’t be deceived. A wave could be very small in one coastal area and extremely large a few kilometers away.
Don’t be curious. You should never get close to the beach to watch a tsunami. When the tsunami is so close that you can see the waves, it will be too late to get out of its way.
Stay away from potentially hazardous areas. A tsunami is not one wave, but a series of waves with several minutes between them. Stay away from potentially hazardous areas until the competent authorities have issued an “all clear” message.
All tsunamis can be destructive. Tsunamis carry everything they find in their path, both when flooding and when receding.
Cooperate with the authorities. During a tsunami emergency, the local emergency management authorities are trying to save lives. Cooperate with them.
Be prepared. Have emergency items at hand. These should include a first aid kit, flashlight, radio, batteries, canned food, distilled water, important documents, etc.
