3.8 Magnitude Earthquake Marks 2026’s First in Antigua

The Eastern Caribbean region experienced a seismic event on the first morning of the new year when a 3.8 magnitude earthquake struck near Antigua and Barbuda. According to precise measurements from the University of the West Indies Seismic Research Centre, the tremor originated at 6:24 a.m. local time, with its epicenter located northwest of Antigua at a depth of approximately 10 kilometers beneath the Earth’s surface.

The seismic activity was perceptible across multiple island territories, with residents from St. Kitts and Nevis to Montserrat reporting noticeable ground vibrations. Despite the widespread awareness of the earthquake, preliminary assessments indicate no structural damage to buildings or infrastructure across the affected islands. Local authorities have confirmed that no injuries or casualties resulted from the geological event.

Monitoring agencies have maintained vigilant observation of the region’s seismic activity following the initial tremor. The Eastern Caribbean region, situated within an active seismic zone, frequently experiences such geological events due to complex tectonic interactions between the Caribbean Plate and neighboring plates. The University of the West Indies Seismic Research Centre continues to track potential aftershocks while providing regular updates to regional emergency management organizations.
