While the tsunami warnings were issued for U.S. territories Puerto Rico and the Virgin Islands, there is no threat to the U.S. Atlantic or Gulf Coast.

Despite the cancellation of tsunami alerts, the scientific community insists that seismic activity in the Caribbean will continue to be a risk factor.

The powerful quake, which struck 10 km below the Earth's surface, prompted the National Weather Service (NWS) Tsunami Warning System to issue tsunami alerts for coastal regions of the Cayman Islands, Jamaica, Cuba, Mexico, Honduras, Bahamas, San Andres and Providencia, Belize, Haiti, Costa Rica, Panama, Nicaragua, and Guatemala.
