Powerful 7.6-Magnitude Earthquake Strikes Caribbean, Tsunami Threat Eases
SAN JUAN, Puerto Rico – A Tsunami Advisory was briefly issued for Puerto Rico and nearby islands on Saturday evening after a massive 7.6-magnitude earthquake struck between Honduras and the Cayman Islands in the Caribbean Sea.
Authorities initially warned of potential sea-level fluctuations and strong ocean currents that could endanger boaters and beachgoers. However, no significant damage was reported in the immediate aftermath of the quake.
Earthquake Impact & Tsunami Advisory
According to the U.S. Geological Survey (USGS), the earthquake's epicenter was located more than 100 miles southwest of George Town, Cayman Islands. The U.S. National Tsunami Warning Center (NTWC) confirmed that the largest water rise—1.2 inches—was recorded at Isla Mujeres, a Mexican island off the Yucatán coast. While the water increase was minimal, the NTWC classified it as a tsunami event.
Shaking Felt Across Multiple Countries
The earthquake triggered light tremors across parts of the Caribbean, including the Yucatán Peninsula, Nicaragua, Honduras, and even southern Cuba. Emergency agencies in Central America and the Caribbean confirmed that no injuries were reported in the immediate aftermath.
Caribbean’s Seismic Activity & Fault Lines
The Cayman Trough, a major tectonic boundary between the North American and Caribbean plates, is responsible for the region's seismic activity. While aftershocks can continue for months or even years, they are generally weaker than the initial earthquake.
Unlike regions along the Pacific Ring of Fire, the Caribbean experiences fewer tsunamis because its fault lines typically do not displace large volumes of seawater. The University of the West Indies has recorded only ten significant earthquake-generated tsunamis in the last 500 years.
History of Major Caribbean Earthquakes
The Caribbean region is no stranger to devastating earthquakes:
- Haiti, 2021 (7.2-Magnitude): Widespread infrastructure damage, though Port-au-Prince was largely spared.
- Haiti, 2010 (7.0-Magnitude): Over 200,000 deaths due to the shallow depth and proximity to the capital.
- Jamaica, 2020 (7.7-Magnitude): Shaking was felt from Central America to South Florida, but no major damage was reported.
Final Thoughts
While the Caribbean remains seismically active, preparedness and early warning systems continue to minimize casualties. Scientists urge vigilance, as earthquakes and aftershocks can still pose risks to coastal communities.
