A magnitude-7.6 earthquake shook the Caribbean, prompting evacuations along coastlines in several islands due to tsunami concerns. Authorities advised moving inland, with projections of waves reaching up to 1 meter. No alerts were issued for the U.S. mainland, but advisories were in place for Puerto Rico and the U.S. Virgin Islands.
On February 8, 2025, a strong magnitude-7.6 earthquake struck the Caribbean Sea, southwest of the Cayman Islands, at approximately 6:23 PM local time. The quake was recorded at a depth of 10 kilometers, with an epicenter located around 130 miles south-southwest of George Town. In response, local authorities advised residents along coastal areas to move inland as a precaution against potential tsunami waves, which were estimated to reach up to 1 meter in height.
The U.S. National Tsunami Warning Center indicated that although there was no tsunami alert for the U.S. mainland, advisories were issued for Puerto Rico and the U.S. Virgin Islands. Hazard Management Cayman Islands specifically called on residents near the coastline to seek higher ground. Conversely, Puerto Rico’s Governor Jenniffer González Colón stated she was in contact with emergency agencies, yet did not deem it necessary for residents to vacate coastal areas.
In addition, the government of the Dominican Republic recommended coastal residents move to higher elevations exceeding 20 meters and at least 2 kilometers inland while instructing vessels to avoid the sea temporarily. The Cuban government similarly encouraged individuals to evacuate beachfront locations. Honduran officials confirmed no immediate damages were reported but advised the public to avoid beaches for safety.
The National Oceanic and Atmospheric Administration later stated that various coastal regions could expect tsunami waves ranging from 1 to 3 meters above normal tide levels, particularly in Cuba, with lesser heights anticipated for Honduras and the Cayman Islands. The NOAA cautioned that actual wave amplitudes may vary due to local topography and forecasting uncertainties.
Understanding the seismic activity in the Caribbean is essential as this region experiences frequent tectonic shifts due to the interaction of the Caribbean and North American plates. Earthquakes of significant magnitudes can pose threats not only in terms of ground shaking but also in the form of induced tsunamis that can lead to coastal hazards. This context is vital for evaluating the responses of government authorities and preparedness for future seismic events.
In summary, the magnitude-7.6 earthquake that struck the Caribbean prompted precautionary measures across multiple islands. Authorities emphasized the need for coastal evacuations and monitoring of tsunami threats, particularly in Puerto Rico, Dominican Republic, Cuba, and Honduras. The situation highlights the importance of proactive emergency preparedness in seismically active regions.
