Tsunami threat issued after 7.7 magnitude earthquake strikes near Jamaica

A tsunami threat message was issued Tuesday after a 7.7 magnitude earthquake struck near Jamaica and Cuba, CNN reports.

The International Tsunami Information Center said Tuesday "hazardous tsunami waves are forecast for some coasts," per Reuters, and CNN writes there was a "threat of tsunami waves reaching 0.3 to 1 meter (about 1 to 3 feet) above tide level for the coasts of Jamaica, Belize, Cuba, Honduras, Mexico and the Cayman Islands."

The earthquake, which struck shortly after 2:00 p.m. Eastern, was felt in Miami and caused "very strong to severe shaking in far western Jamaica," The Weather Channel reports, citing the U.S. Geological Survey. The Associated Press also reports it could be felt "strongly" in Santiago, where a witness said, "We were all sitting and we felt the chairs move. We heard the noise of everything moving around."

There have not been reports of any casualties, and according to the National Tsunami Warning Center, there is no tsunami threat for the eastern United States or the Gulf of Mexico. The Washington Post reports, though, this "appeared to be one of the biggest [earthquakes] on record in the Caribbean, and the largest since 1946."
