A 7.6 magnitude earthquake in the Caribbean Sea triggered a tsunami advisory for Puerto Rico and the Virgin Islands, with authorities urging residents to avoid coastal areas. The National Tsunami Warning Center canceled the advisory later in the evening, although strong currents could persist. While Cuba may face tsunami waves of up to 3 meters, no tsunami threats were issued for the U.S. mainland.
A significant earthquake measuring 7.6 magnitude struck the Caribbean Sea on Saturday, approximately 130 miles southwest of Georgetown, Cayman Island, around 6:30 p.m. as reported by the U.S. Geological Survey (USGS). This quake prompted a temporary tsunami threat advisement for Puerto Rico and the Virgin Islands, leading officials to recommend that residents avoid beaches and coastal areas due to potential sea level hazards and flooding risks.
The regions surrounding the Caribbean are known to be seismically active, situated near the tectonic boundary between the North American and Caribbean plates. The recent earthquake was a result of strike-slip faulting in the shallow crust, characterized by lateral movement along a steeply dipping structure. Such geological phenomena necessitate vigilance regarding subsequent tsunami threats, as demonstrated by this event.
In summary, the notable earthquake in the Caribbean Sea raised initial tsunami concerns for nearby territories, prompting precautionary measures. Although advisories have since been lifted, the potential for strong currents remains, necessitating continued caution in affected areas. The geological activity underscored the ongoing seismic risks in this region, reinforcing the importance of preparedness and awareness.
