The month's largest event in Antigua and Barbuda was a magnitude 6.1 earthquake near Codrington, Antigua and Barbuda on 16 May 2026 at 14:50 UTC. A magnitude 6.1 earthquake radiates roughly 21,301 tons of TNT equivalent in seismic energy.

That is well above the Antigua and Barbuda monthly average of 1 events over the period we cover — an unusually active month.

100% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 0% deep-focus (over 300 km). Almost everything here is crustal. That is characteristic of transform faulting or continental deformation rather than subduction — and it means shaking at the surface is strong for the magnitudes involved.

By band, the catalogue holds 2 in the magnitude 6 range.

Activity peaked on 16 May, when 2 events were recorded.

The month's largest events were M6.1 near Codrington, Antigua and Barbuda on 16 May at 63 km; M6.0 near Codrington, Antigua and Barbuda on 16 May at 30 km.
