Earthquakes in Cuba — June 2026

4 earthquakes were recorded in Cuba during June 2026, an average of 0.1 per day.

4 reached magnitude 4 or above and 2 reached magnitude 5 or above. The average focal depth was 24 km.

The month's largest event in Cuba was a magnitude 6.4 earthquake near Mantua, Cuba on 08 June 2026 at 18:00 UTC. A magnitude 6.4 earthquake radiates roughly 60,036 tons of TNT equivalent in seismic energy.

That is well above the Cuba monthly average of 3 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 4 range, 2 in the magnitude 6 range.

Activity peaked on 08 June, when 2 events were recorded.

The month's largest events were M6.4 near Mantua, Cuba on 08 June at 33 km; M6.1 near Mantua, Cuba on 08 June at 26 km; M4.9 near Mantua, Cuba on 15 June at 20 km.

That is 45% above the 3 events Cuba averages per month across the 4 months on record.

This month also holds the strongest earthquake recorded in Cuba in our entire catalogue.
