If you want to keep up with the National Weather Service’s Pacific Tsunami Warning Center advisories for the Caribbean Sea, you can monitor any warnings yourself.
The latest warning says that there was an earthquake of 6.9 magnitude in the South Sandwich Islands region. The statement says: “There is the small possibility of a local or regional tsunami that could affect coasts located usually no more than a few hundred kilometers from the earthquake epicenter. This statement applies to countries within the bordering Caribbean Sea…except for Puerto Rico and the Virgin Islands.”
It’s quite an interesting site, with maps of various regions. The site also gives information to help communities that are at risk to better prepare themselves for a tsunami.
The site also has an extensive FAQ section on tsunamis.
