Earthquakes in Cuba — March 2026
5 earthquakes were recorded in Cuba during March 2026, an average of 0.2 per day.
5 reached magnitude 4 or above and 2 reached magnitude 5 or above. The average focal depth was 10 km.
The month's largest event in Cuba was a magnitude 5.8 earthquake near Maisí, Cuba on 17 March 2026 at 04:28 UTC. A magnitude 5.8 earthquake radiates roughly 7,558 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, and up from the 1 recorded the previous 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 3 in the magnitude 4 range, 2 in the magnitude 5 range.
Activity peaked on 17 March, when 2 events were recorded.
The month's largest events were M5.8 near Maisí, Cuba on 17 March at 12 km; M5.0 near Maisí, Cuba on 06 March at 10 km; M4.7 near Maisí, Cuba on 17 March at 10 km.
That is 82% above the 3 events Cuba averages per month across the 4 months on record.
