An earthquake with a magnitude of 7.6 struck the Caribbean Sea on Saturday, prompting tsunami advisories in several regions. The US Geological Survey (USGS) reported the earthquake at 6:23 p.m. ET, with its epicenter located 129 miles southwest of Georgetown, Cayman Islands. In response to the seismic activity, the US National Tsunami Warning Center (NWTC) issued a tsunami threat for Puerto Rico and the Virgin Islands, which was later canceled. However, advisories remained in effect for Cuba, Honduras, and the Cayman Islands.
The NWTC's decision to issue tsunami alerts was based on the potential threat posed by the earthquake's significant magnitude. While the advisory for Puerto Rico and the Virgin Islands was eventually lifted, authorities continued to caution other areas in the Caribbean. The potential for tsunami waves raised concerns among residents and officials in Cuba, Honduras, and the Cayman Islands.
In Cuba, tsunami waves ranging from 1 to 3 meters above tide level were considered possible. Meanwhile, in Honduras and the Cayman Islands, the anticipated wave heights were estimated between 30 centimeters to 1 meter above tide level. These waves were expected to arrive between 8 p.m. ET and 10:30 p.m. ET on Saturday, prompting local authorities to remain vigilant and prepared for any developments.
The USGS's report highlighted the geographical proximity of the earthquake's epicenter to the Cayman Islands, emphasizing the need for continued monitoring of seismic activity in the region. The NWTC's prompt response in issuing and adjusting tsunami advisories underscored the importance of readiness in managing potential natural disasters.
