Earthquakes in Cuba

No events have been recorded in Cuba in the past 30 days, and 6 of the events on record reached magnitude 5 or above — the level at which damage becomes a genuine concern for vulnerable construction. Activity here is almost entirely crustal, which means shaking at the surface is strong relative to the magnitudes involved.

11 earthquakes have been recorded in Cuba in our catalogue, 0 of them in the past 30 days.

The average magnitude is 5.2 and the average focal depth 16 km. 11 events reached magnitude 4 or above and 6 reached magnitude 5 or above.

The strongest earthquake recorded in Cuba in this period was a magnitude 6.4 event near Mantua, Cuba on 08 June 2026, at a depth of 33 km. A magnitude 6.4 earthquake radiates roughly 60,036 tons of TNT equivalent in seismic energy.

Locations recording the most events include Maisí (6), Mantua (4), Guamá (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 5 in the magnitude 4 range, 4 in the magnitude 5 range, 2 in the magnitude 6 range.

The busiest single day was 17 March 2026, with 2 recorded events.

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