A 7.6-magnitude earthquake slammed the Caribbean Sea — prompting several tsunami warnings, which were later canceled, weather officials say.

The earthquake began Saturday night about 130 miles south-southwest of George Town, the capital of the Cayman Islands, according to the U.S. Geological Survey. A tsunami threat was initially forecast for 20 countries and islands, including the Bahamas, Belize, the Cayman Islands, Cuba, Haiti, Jamaica and Turks and Caicos.

The U.S. National Tsunami Warning Center had issued an advisory for Puerto Rico and the U.S. Virgin Islands, though it was later retracted.

The Caribbean has seen aftershocks, smaller earthquakes, since the 7.6-magnitude quake, said Ana Torres-Vazquez, a meteorologist at NWS Miami. The aftershocks haven’t caused any reported damage.

The sea has also had no tsunami activity, and South Florida was not impacted, Torres-Vazquez added.
