Earthquakes in Uganda
Uganda has catalogued 73 M4+ earthquakes since 2005 (ranked 89th of 187 countries), with the strongest reaching magnitude M6.6.
Uganda ranks 89th 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
Uganda is moderately seismically active, above the global median, with 73 M4+ earthquakes logged since 2005 and 5 major M6+ events since 1900, the strongest reaching magnitude 6.6.
- 1912
- busiest year (1 major events)
- 17 km
- average recorded event depth

- 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 Greenland sits immediately above at 77 events and Bosnia and Herzegovina sits immediately below at 69.

Observed impact record
What ComCat observed after earthquakes in Uganda
USGS recorded Modified Mercalli Intensity (MMI) for 4 events in this catalogued record; their average observed intensity was MMI 7.6. These are only events with an observation, not an estimate of future shaking or a safety rating.

Where Uganda sits in the catalog
Rank 89th of 187 tracked countries (52th percentile by M4+ count since 2005). On the M4+ activity ladder Greenland sits immediately above at 77 events and Bosnia and Herzegovina sits immediately below at 69.
- Greenland - next more active (77 M4+)
- Bosnia and Herzegovina - next less active (69 M4+)

What this shows Uganda's most active year for major earthquakes was 1912 (1 M6+ events). Major-quake counts are irregular, they track the episodic release of tectonic stress, not a smooth trend.
0 of 73 catalogued M4+ events since 2005 reached M6.0 or higher.
