Earthquakes in Cuba
Cuba has catalogued 96 M4+ earthquakes since 2005 (ranked 81st of 187 countries), with the strongest reaching magnitude M7.0.
Cuba ranks 81st of 187 countries by catalogued seismic activity - a country with limited but non-zero seismic activity, averaging about 5 M4+ events a year alongside 6 significant M6+ earthquakes since 1900. The M6+ record here is thin - 6 events in all, so a single quake moves every figure on this page.

- of events are shallow (<70 km, the most damaging kind)
Average catalogued magnitude is 4.6 - most events are moderate M4-5 tremors that are felt but rarely cause damage. On the M4+ activity ladder Cyprus sits immediately above at 97 events and Eritrea sits immediately below at 93.

Observed impact record
What ComCat observed after earthquakes in Cuba
USGS recorded Modified Mercalli Intensity (MMI) for 5 events in this catalogued record; their average observed intensity was MMI 6.3. These are only events with an observation, not an estimate of future shaking or a safety rating.

What this shows Cuba's most active year for major earthquakes was 1917 (1 M6+ events). Major-quake counts are irregular, they track the episodic release of tectonic stress, not a smooth trend.
2 of 96 catalogued M4+ events since 2005 reached M6.0 or higher.
