Earthquakes in Croatia
Croatia has catalogued 65 M4+ earthquakes since 2005 (ranked 93rd of 187 countries), with the strongest reaching magnitude M6.4.
Croatia ranks 93rd of 187 countries by catalogued seismic activity - a country with limited but non-zero seismic activity, averaging about 3 M4+ events a year alongside 5 significant M6+ earthquakes since 1900. The M6+ record here is thin - 5 events in all, so a single quake moves every figure on this page.

The verdict
Croatia is moderately seismically active, above the global median, with 65 M4+ earthquakes logged since 2005 and 5 major M6+ events since 1900, the strongest reaching magnitude 6.4.

- of events are shallow (<70 km, the most damaging kind)
Average catalogued magnitude is 4.4 - most events are moderate M4-5 tremors that are felt but rarely cause damage. On the M4+ activity ladder Barbados sits immediately above at 66 events and Bangladesh sits immediately below at 64.

What this shows Croatia's most active year for major earthquakes was 1962 (2 M6+ events). Major-quake counts are irregular, they track the episodic release of tectonic stress, not a smooth trend.
1 of 65 catalogued M4+ events since 2005 reached M6.0 or higher.
