Magnitude 7.6 Earthquake Triggers Tsunami Advisory in Caribbean Sea

A magnitude 7.6 earthquake near the Cayman Islands triggered a temporary tsunami advisory for Puerto Rico and the Virgin Islands. NOAA warned of potential tsunami waves for Cuba, and though the advisory was lifted, caution was advised due to strong currents. No damage was reported in the aftermath of the tremor.

On Saturday, a significant earthquake with a preliminary magnitude of 7.6 occurred in the Caribbean Sea, approximately 130 miles southwest of Georgetown, Cayman Islands. According to the U.S. Geological Survey (USGS), the seismic event transpired at approximately 6:30 p.m. local time. This earthquake prompted a temporary tsunami advisory for Puerto Rico and the Virgin Islands, urging residents to avoid coastal areas due to potential sea level hazards and flooding risks.

The U.S. National Tsunami Warning Center (NTWC) lifted the tsunami advisory around 8:15 p.m., although they cautioned that “strong and unusual currents may continue. Be careful near the water and use caution,” as stated on the platform X. Additionally, the National Oceanic and Atmospheric Administration (NOAA) indicated that Cuba might experience tsunami waves ranging between 1 to 3 meters above the tidal level, encouraging the local government to urge the evacuation of beachfront areas.

NOAA highlighted that actual wave amplitudes could differ from forecasted levels due to inherent uncertainties and local geographical features. The NTWC confirmed that there was no tsunami alert for the U.S. mainland following the earthquake. The USGS explained that the earthquake resulted from strike-slip faulting at the boundary between the North America and Caribbean tectonic plates, with potential rupture mechanisms identified.

In summary, a notable earthquake of magnitude 7.6 struck near the Cayman Islands, triggering a temporary tsunami advisory for Puerto Rico and the Virgin Islands, which was subsequently canceled. NOAA issued warnings for potential tsunami waves along the coasts of Cuba, while no damage was reported post-event. Authorities continue to advise caution around coastal areas due to residual currents.
