Earthquakes in Antigua and Barbuda

No events have been recorded in Antigua and Barbuda in the past 30 days, though the great majority are too small to be felt at the surface. Activity here is almost entirely crustal, which means shaking at the surface is strong relative to the magnitudes involved.

4 earthquakes have been recorded in Antigua and Barbuda in our catalogue, 0 of them in the past 30 days.

The average magnitude is 5.2 and the average focal depth 46 km. 4 events reached magnitude 4 or above and 2 reached magnitude 5 or above.

The strongest earthquake recorded in Antigua and Barbuda in this period was a magnitude 6.1 event near Codrington, Antigua and Barbuda on 16 May 2026, at a depth of 63 km. A magnitude 6.1 earthquake radiates roughly 21,301 tons of TNT equivalent in seismic energy.

Locations recording the most events include Codrington (4).

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 4 range, 2 in the magnitude 6 range.

The busiest single day was 16 May 2026, with 2 recorded events.

No event in this record carries a USGS link to NOAA tsunami information.
