On a Saturday morning, a 6.5-magnitude earthquake rattled waters northeast of the twin-island nation of Antigua and Barbuda, leaving residents across both islands reeling from a jolt of fear, momentary confusion, and eventual relief when no severe harm was reported. The Seismic Research Centre (SRC) based at the University of the West Indies documented the event, noting the tremor struck at 10:50 a.m. local time at a depth of 31 kilometers beneath the ocean surface.
Preliminary positioning data places the earthquake’s epicenter at 17.39 degrees north latitude and 61.18 degrees west longitude, roughly 80 kilometers from St. John’s, the capital of Antigua. The epicenter is also approximately 132 kilometers from Brades, the administrative center of Montserrat, and 132 kilometers north-northeast of Guadeloupe’s largest city, Pointe-à-Pitre. The SRC emphasized that this initial location was calculated automatically by machine algorithms, and will remain provisional until expert analysts complete a full manual review of the collected seismic data.
In the hours immediately after the quake, there were no confirmed reports of human casualties or widespread structural damage, even as residents across dozens of communities reported feeling strong, sustained shaking across the islands. A resident living on Old Parham Road reported that household and store items tumbled from shelves during the shaking, with other communities including Yorks, Powells, Liberta, and New Winthorpes also recording intense tremors that were impossible to miss.
Social media posts from local residents captured a range of experiences. One user described the quake as “super strong,” while another characterized it as “very big and heavy and long.” Many locals said they experienced moments of disorientation when the shaking first started; one woman, who was showering when the quake hit, shared online that she initially assumed her husband was playing a practical joke to startle her.
Other accounts detailed scattered scenes of panic in public spaces. One commenter reported that customers and staff rushed out of a hardware store on Old Parham Road as the shaking grew more intense, with many fearing the building could sustain structural damage. In the immediate aftermath of the tremor, questions about road conditions and neighborhood safety spread rapidly across local social media platforms, as residents sought updates to confirm loved ones were unharmed and infrastructure remained intact. For many, the lack of major harm prompted relief: one resident wrote online “Thank God for your grace and mercy towards us.”
The eastern Caribbean is no stranger to seismic activity. The entire region sits along the complex boundary between the Caribbean tectonic plate and the North American tectonic plate, creating constant geological stress that regularly produces tremors felt across multiple island nations in the area.
