A powerful earthquake measuring 7.6 on the Richter scale struck the Caribbean Sea on Saturday evening, prompting immediate tsunami warnings across several regions, including Puerto Rico and the Virgin Islands. The earthquake occurred at 6:23 PM ET, approximately 209 kilometers southwest of George Town, Cayman Islands, according to the United States Geological Survey (USGS).
The tremor's shallow depth of about 10 kilometers contributed to the intensity of the shock felt throughout the region. Various emergency management authorities, including the U.S. Tsunami Warning Center, quickly issued alerts for potential tsunami waves hitting coastal areas of Central America and the Caribbean.
Significant variations were anticipated along the coasts of Mexico and Central America, with predictions of waves ranging from one to three meters. The governor of Quintana Roo, Mara Lezama, confirmed on social media platforms about the seismic activity being felt across her state, but assured the public of no immediate threats or damage reported yet. "We have activated Civil Protection protocols to monitor the situation continuously," she said, emphasizing the preparedness of local agencies.
The satellite-based monitoring service SkyAlert stated following the earthquake, their assessment indicated no vertical displacement of the seafloor, which is often associated with substantial tsunami risks. Consequently, the likelihood of dangerous waves was significantly decreased. Official communications confirmed, "While fluctuations and strong currents were anticipated, they did not pose serious threats to the general population across Mexican coasts," cited the bulletin released by the Navy's Tsunami Alert Center (CAT-Semar).
By 9 PM ET, minor sea level fluctuations began as expected, but later assessments led the National Tsunami Warning Center to lift tsunami warnings after confirming there was no destructive tsunami generated. Reports indicated only minimal impacts were felt around the Caribbean, as no significant structural damages or casualties were documented.
The seismic event, which local authorities referred to as one of the most substantial they have encountered since 2021, is noteworthy not only for its local intensity but also for occurring after 1,276 days without significant earthquakes globally reaching magnitude 8 or above.
Historically, the region's geological activity raises concerns due to the susceptibility of various islands and coastal areas to seismic events and their potential consequences. The last comparable tremor was recorded at 7.2 magnitude, which struck Haiti back in 2021, resulting in significant human and material costs.
Following the earthquake on February 8, local and international aid agencies have remained vigilant, preparing for the aftermath and reinforcing disaster response strategies. Evacuation protocols were reiterated among communities, especially along vulnerable coastal areas, to promote public safety during potential aftershocks and fluctuations.
This situation has drawn attention to the geological instability of the region, reminding us of the natural disasters' unpredictability and serving as a prompt for emergency preparedness among the local population.
Overall, this seismic event serves as another stark reminder of the Caribbean's volatile tectonic nature and highlights the importance of preparedness for residents living along coastal areas.
