A powerful 7.7 magnitude earthquake struck Tuesday in the Caribbean Sea, between Cuba and Jamaica, according to the United States Geological Survey.
New York Times reporter Carol Rosenberg tweeted that the "earth is literally shaking here" at the press room at Guantanamo Bay in Cuba.
Rosenberg was at Camp Justice at Guantanamo Bay in Cuba covering a 9/11 pretrial hearing.
The earthquake was centered 125 kilometers northwest of Lucea, Jamaica, the USGS said. It's not immediately clear if there are damage or injuries. The earthquake was centered only about 10 kilometers (6 miles) beneath the surface.
The USGS initially estimated the earthquake was a 7.3 magnitude, before upgrading it to 7.7.
The earthquake was so powerful that some people in Miami said they felt their building shake, CBS Miami reported.
The National Weather Service for San Juan, Puerto Rico said there was no tsunami threat for Puerto Rico and the U.S. Virgin Islands.
