Plan & Prepare Tsunamis
 - Information provided by
The U.S. Virgin Islands, along with the rest of the Caribbean, is considered a region with high levels of vulnerability and threat for tsunamis. Tsunamis are enormous waves caused by an underground disturbance such as an earthquake. They can move hundreds of miles per hour, and hit land with waves topping 100 feet in height.

Since 1842 at more than 3,500 people have lost their lives to tsunamis in the Caribbean. In recent years, there has been an explosive population growth and influx of tourists along the Caribbean coasts increasing the tsunami vulnerability of the region. Other events, such as the earthquakes and tsunamis in the Indian Ocean (2004), Samoa (2009, Haiti and Chile (2010) and Japan (2011), attest to the importance of proper planning for tsunami response.

All-Hazards Warning System
As part of VITEMA's continuing efforts to ensure that the Virgin Islands is prepared for any emergency, including tsunamis, special warning sirens are being installed throughout the territory. 
Understanding the difference between the terms that identify a tsunami hazard: advisory, watch and warning. For a detailed explanation of these terms, see
Plan to act quickly.
If you are in coastal waters and notice a dramatic recession of water from the shoreline you should heed nature's warning that a tsunami is approaching.
Move inland immediately and do not return to the flooded and damaged areas until officials say it is safe to do so.
