Climatologist Dale Destin Urges Tsunami Readiness After Powerful Earthquake Near Antigua

Climatologist Dale Destin is urging greater tsunami awareness and preparedness across Antigua and Barbuda following Saturday’s strong earthquake, which rattled the country and served as a reminder of the region’s vulnerability to seismic hazards.

The earthquake struck at approximately 10:50 a.m. on May 16 and measured magnitude 6.1 according to the United States Geological Survey (USGS), while the University of the West Indies Seismic Research Centre recorded it at magnitude 6.4.

The tremor was felt widely across the Northeastern Caribbean and ranks among the strongest earthquakes recorded near Antigua and Barbuda in modern history.

Although there were no immediate reports of deaths or major structural damage, videos circulating on social media showed products falling from shelves in businesses and supermarkets as residents reacted in alarm.

In an analysis following the event, Destin warned that while Saturday’s earthquake did not generate a tsunami, the incident should reinforce the need for public readiness.

He noted that stronger earthquakes in the region have historically produced destructive consequences and said preparedness remains critical.

Destin explained that Antigua and Barbuda sits within a tectonically active region where the Atlantic Plate is forced beneath the Caribbean Plate, making earthquakes and volcanic activity a natural part of the Eastern Caribbean landscape.

Historical records show the region has experienced several major earthquakes, including the devastating 1843 Antigua–Guadeloupe earthquake and the magnitude 7.5 earthquake northwest of Antigua in 1974.

He also highlighted the importance of recognising natural warning signs associated with potential tsunami threats, including prolonged shaking, sudden sea retreat and unusual ocean activity. Residents in coastal areas were encouraged to move inland or seek higher ground immediately if such signs occur.

Destin stressed that awareness and timely action remain among the strongest safeguards against future disasters. The recent earthquake, he said, should serve not only as a moment of reflection but as a wake-up call for greater preparedness nationwide.
