A moderate seismic event measuring 3.8 on the Richter scale struck the Eastern Caribbean region early Tuesday morning, as confirmed by the University of the West Indies Seismic Research Centre. The tremor originated at precisely 7:33 a.m. local time, with its hypocentre positioned 17 kilometres beneath the Earth’s surface. Seismologists pinpointed the epicentre approximately 79 kilometres southeast of St John’s, the capital city of Antigua and Barbuda.
The earthquake’s impact radiated across multiple territories, registering 73 kilometres northeast of Point-à-Pitre in Guadeloupe and 112 kilometres east of Brades, Montserrat. Despite the quake’s significant depth and moderate intensity, preliminary assessments indicate no immediate structural damage or casualties across the affected islands.
The Seismic Research Centre issued a technical note clarifying that initial measurements were automatically generated by sophisticated monitoring systems. Scientists emphasized that these preliminary readings remain subject to potential revision as seismologists conduct comprehensive analysis of seismic waveforms and geological data. The center maintains continuous monitoring of aftershock potential, though historical patterns suggest minimal likelihood of significant follow-up activity for quakes of this magnitude.
Regional emergency response teams reported standard post-earthquake protocols were activated, with comprehensive infrastructure checks conducted across vulnerable areas. The Caribbean Disaster Emergency Management Agency confirmed readiness to provide support if necessary, though no assistance requests were received.
