Earthquakes in the Cayman Islands

No events have been recorded in the Cayman Islands in the past 30 days, of which 13 reached magnitude 4 or above, the point at which shaking becomes widely noticeable. Activity here is almost entirely crustal, which means shaking at the surface is strong relative to the magnitudes involved.

13 earthquakes have been recorded in the Cayman Islands in our catalogue, 0 of them in the past 30 days.

The average magnitude is 4.7 and the average focal depth 10 km. 13 events reached magnitude 4 or above and 3 reached magnitude 5 or above.

The strongest earthquake recorded in the Cayman Islands in this period was a magnitude 7.6 event near George Town, Cayman Islands on 08 February 2025, at a depth of 10 km. A magnitude 7.6 earthquake radiates roughly 3.8 million tons of TNT equivalent in seismic energy.

Locations recording the most events include George Town (10), East End (2), Bodden Town (1).

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 10 in the magnitude 4 range, 2 in the magnitude 5 range, 1 in the magnitude 7 range.

The busiest single day was 09 February 2025, with 3 recorded events.

1 of these events carry a USGS link to NOAA tsunami information. That link flag does not mean a tsunami occurred or that a warning was issued.
